1.3 GENERAL INFORMATION

— Printed 603.95.827 – 1 Ed. - Base 02/2014

1.3 GENERAL INFORMATION

Refer to NEW DAILY Bodybuilders instructions (Print number 603.95.791).

1.4 TYPES OF POWER TAKE-OFF (PTO)

Only one PTO can be fitted for each type of power take-off.

Power take-off to the gearbox


The power take-off from the gearbox can be electromechanical or electro-pneumatic (Market retro-fit).

There are two PTO management methods, to be defined with IVECO: management with own control unit or with EM.

Power take-off to the transmission


Power take-off to the engine


”Transfer case output shaft PTO” power take-off

To define with IVECO.

”Transmission output shaft PTO” power take-off

To define with IVECO.

"Electro-pneumatic" power take-off (PTO2)

1.5 PTO MANAGEMENT

▶ Operations which do not comply with the instructions specified by IVECO or carried out by nonqualified personnel can cause severe damage to on-board systems, affect driving safety, reliab-ility and good operation of the vehicle and cause considerable damage which is not covered bywarranty.

The power take-offs are managed directly by the Expansion Module (EM) control unit in Figure 1. The EM is able to manage twodifferent PTOs.

Power take-off PTO1 can be fitted solely and exclusively on the gearbox.


1.5 PTO MANAGEMENT7

— Printed 603.95.827 – 1 Ed. - Base 02/2014

126269 Figure 1

EM CONTROL UNIT (located in the central section of the dashboard)

Different parameters can be configured for each PTO by IVECO Customer Service:

● Engagement restrictions,● disengagement conditions,● control on engine (engine rpm request of maximum torque limit configuration or maximum rpm limit configuration).

Note The control parameter on the engine cannot be configured for a CNG engine.

Activation of the PTO

A button in the middle of the dashboard in the driver’s cab engages and disengages the PTO1 (Figure 2). This is a rocker button.

A warning light on the button indicates the status of PTO1:

● warning light off (a): PTO1 disengaged;● warning light fixed on (b): PTO1 engaged;● Flashing warning light: transient stage from (a) → (b) or from (b) → (a) in which the EM searches, respectively, to engage or

disengage PTO1.

Since the EM can control up to two PTOs, up to two PTO controls (one button for PTO1 and one switch for PTO2) can be in-cluded. The switch for PTO2 is a stable switch and is the responsibility of the Bodybuilder.


1.5 PTO MANAGEMENT

— Printed 603.95.827 – 1 Ed. - Base 02/2014

The Bodybuilder must also see to the connections between PTO2 and the Bodybuilder connectors. For a more detailed descrip-tion, refer to Chapter 1.6 "Wiring Diagram" ( ➠ Page 15).

209820 Figure 2

If the PTO1 button is faulty, a new one can be purchased directly through IVECO.

Standard PTO configuration supplied as default by IVECO

IVECO supplies the EM control unit as a standard with just PTO1 configured, the wiring and PTO button. Power take-off PTO1can be fitted solely and exclusively on the gearbox.

PTO1 on Manual Gearbox

PTO engage

The purpose of this action is to prepare equipment for work.

During execution of the operating sequence the driver is assisted to prevent steering errors.

The correct operations to be carried out are:

1. stop the motion of the vehicle;2. check/engage neutral gear if the operation is set with the vehicle at a standstill or engage the gear that the equipment must

operate in;3. depress the clutch pedal4. press and release the button on the dashboard that controls engagement of the power take-off (see Figure 2);5. the indicator light starts to flash until the PTO is correctly engaged;6. at this point the clutch can be released.

If there is "Engagement Restriction" (see paragraph "Engagement restriction" ( ➠ Page 10)) the PTO is not engaged. An error mes-sage appears on the instrument panel to advise the driver. The error is displayed at each subsequent attempt to engage PTO aslong as the cause(s) of the restriction remains. When the cause of the restriction has been eliminated PTO can be engaged by fol-lowing the procedure described above.


1.5 PTO MANAGEMENT9

— Printed 603.95.827 – 1 Ed. - Base 02/2014

Disengagement of the PTO


1. stop the operation of the equipment and press the clutch pedal;2. press the button which controls power take-off engagement (see Figure 2);3. the indicator light starts to flash until it switches OFF completely when the PTO is correctly disengaged;4. at this point the clutch can be released.

If there is "Shut-off Condition" (disengagement condition, see Paragraph "PTO disengagement" ( ➠ Page 10)) the PTO is disen-gaged automatically. If no torque is applied, the PTO is disengaged. An error message appears on the instrument panel to advise thedriver. When the cause of the disengagement condition has been eliminated PTO can be engaged by following the procedure de-scribed above and keeping it switched on.

▶ The power take off can be switched off only when no torque is applied to it (either engine ortransmission).

PTO1 on Automatic Gearbox

PTO engage

The purpose of this action is to prepare equipment for work.

During execution of the operating sequence the driver is assisted to prevent steering errors.


1. stop the motion of the vehicle;2. check the gearbox is in neutral / engage neutral;3. press the button on the dashboard that controls engagement of the power take-off (see Figure 2);4. the indicator light starts to flash until the PTO is correctly engaged;

Disengagement of the PTO


1. stop the operation of the equipment;2. press the button which controls power take-off disengagement (see Figure 2);3. the indicator light starts to flash until it switches OFF completely when the PTO is correctly disengaged;4. at this point the vehicle can be moved.

▶ The power take off can be switched off only when no torque is applied to it (either engine ortransmission).

PTO operation when errors are present (Degraded Mode)

"Degraded Mode" allows the driver to progress the PTO operation despite an error being present.

The system enters Degraded Mode only if at least one disengagement condition has previously been configured.

The errors that start Degraded Mode are:

● a missing CAN message:● an engagement signal in which the value is outside of the permitted range.


1.5 PTO MANAGEMENT

— Printed 603.95.827 – 1 Ed. - Base 02/2014

In this mode, the error detected is displayed on the instrument panel. When the error message appears the driver must pressthe MODE button. A message will then be displayed on the instrument panel inviting the driver to decide whether they wish tocontinue to operate the PTO under their own command or terminate the operation, automatically disengaging the PTO.

If no instruction is given within the Degraded_Mode_Timeout period (20 seconds), the PTO operation is interrupted automatically.

PTO customized configuration

Depending on foreseen vehicle use Bodybuilders are required to contact IVECO Customer Service, for carrying out the necessaryExpansion Module control unit programming for operation of a PTO.

Keeping to the following instructions the Bodybuilder will be able to organise system configuration in advance.

If special adjustments are necessary, the Bodybuilder can programme them, for each individual power take off, by contactingIVECO Customer Service.

Except for express warnings, the following instructions apply to each individual power take-off.

Engagement restrictions

Engagement restrictions are used if the user wishes to impede engagement of the PTO to check (or not) the set conditions. Therestriction conditions are considered as such only if they have a temporary duration of a few seconds or more. When this time haselapsed the EM control unit detects the presence of the restriction. A warning message will be displayed and engagement will nottake place.

The table below provides a list of all possible engagement restrictions. The user chooses which restrictions to enter for their ownapplication from those indicated.

1.5 PTO MANAGEMENT11

— Printed 603.95.827 – 1 Ed. - Base 02/2014

Disengagement conditions

The disengagement conditions are those in which the PTO switches itself off automatically. The disengagement conditions are con-sidered as such only if they have a temporary duration of a few seconds or more. When this time has elapsed the EM control unitdetects the presence of the disengagement condition. A warning message will be displayed on the instrument panel and the PTOwill automatically disengage.

Note The automatic disengagement by the EM depends on the PTO load. In some situations, when the warning message is displayed inthe instrument panel, the PTO is not switched off automatically. In this case it is necessary to:

a) with a manual transmission

• with the vehicle stationary, operate the clutch

• with the vehicle moving, put gear into neutral

b) with an automatic transmission

• with the vehicle moving, put gear into neutral

The table below contains the list of possible disengagement conditions; The user chooses which to enter for their own applicationfrom those indicated.

1.5 PTO MANAGEMENT

— Printed 603.95.827 – 1 Ed. - Base 02/2014

Checks on the engine

When the PTO is engaged the following checks on the engine are connected:

● RPM request (not available on CNG engines);● configuration of maximum RPM limit (not available on CNG engines);● configuration of maximum torque limit (a limit at lower torque values than necessary to support idling should not be set for

CNG engines, otherwise the engine will cut out).

Note During the "rpm request" check the engine speed cannot be changed using the Cruise Control and/or the accelerator pedal.

Engine control ends when the PTO is released.

The parameter PTO[x]_SwActCfg (x = 1, 2 represents the PTO involved) defines whether to associate the control on theengine with the pressure of the button for PTO engagement:

Table 5Parameter Configuration

PTO[x]_SwActCfgNo control requested

Engine control requested as soon as the PTO engagement button is pressed

▶ When the aforementioned parameter is set and when there are engagement restrictions, theengine control is applied for a certain period of time (a few seconds) until the EM control unit nolonger detects the restriction.


The parameter PTO[x]_FbkActCfg (x = 1, 2 refers to the PTO involved) defines whether to associate the engine control tothe successful engagement of the PTO, therefore only after the engine has sent a positive feedback to the EM.

Table 6Parameter Configuration

PTO[x]_FbkActCfgNo control requested

Engine control requested only after the PTO has been successfully engaged.



1.5 PTO MANAGEMENT13

— Printed 603.95.827 – 1 Ed. - Base 02/2014

Parameters can only be set for PTO2

Engagement Timeout

If power take-off PTO2 requires a greater engagement time than two seconds, it is possible to act on the Engagement Timeoutparameter PTO[x]_ERtimeout (x = 2, represents the PTO involved) that stabilises the time level outside of which an engage-ment restriction condition (if configured) is considered as such.

The EM control unit assesses the outcome of the PTO2 engagement and, if engagement has not been successful, displays any En-gagement Timeout errors only once the "Engagement Timeout" time has elapsed.

Note The PTO[x]_ERtimeout parameter can be set by IVECO Customer Service.

Disengagement Timeout

If power take-off PTO2 requires a greater disengagement time than two seconds, it is possible to act on the Engagement Timeoutparameter PTO[x]_SCtimeout (x = 2, represents the PTO involved) that stabilises the time level outside of which an engage-ment restriction condition (if configured) is considered as such.

The EM control unit assesses the outcome of the PTO2 disengagement and, if disengagement has not been successful, displays anyDisengagement Timeout errors only once the Disengagement Timeout.

Therefore, the EM control unit will detect the presence of the disengagement condition only once the Disengagement Timeouttime has elapsed. Within 10 seconds a warning message will be displayed on the Instrument Panel and the PTO will automaticallydisengage.

Note The PTO[x]_SCtimeout parameter can be set by IVECO Customer Service.

3.3 CANOpen

This chapter covers:

● a short overview of the main concepts and abbreviations used.● a breakdown of CANOpen communication objects used in the Expansion Module.

Knowledge of the standards referred to below is assumed.

The Expansion Module CANOpen network operates in accordance with the following standards:

● CiA DS- 301 V4.02 (Application Layer and Communication Profile)● CiA DR- 303-3 V1.2 (Indicator Specification)● CiA DS- 306 V1.3: (Electronic data sheet specification for CANopen)● CiA DS- 402 V2.0 (Device Profile for Drives and Motion Control)● CIA DS 413-1 V2.0 (Device profile for truck gateways - Part 1: General definitions and default communic-

ation objects)

Note Further information can be obtained from the official CAN in Automation association website www.can-cia.org.

CANOpen communication

CANOpen is a higher-layer protocol based on the CAN serial bus system. CANOpen requires the hardware of a connecteddevice to include a CAN receiver (CAN-transceiver) and a CAN controller as established by ISO 11898.

Communication profile CANOpen, CiA DS-301 includes both cyclic communication and event-oriented communication thatmakes it possible to minimise the bus load, maintaining ultra-short reaction times. It is possible to achieve high communicationperformance at relatively low speeds, thus reducing problems linked with EMC and wiring costs.

The physical medium of CANOpen is a differential pair bus line with common return compliant with ISO 11898. Bus length is lim-ited by communication speed (Baudrate) as follows:

Table 3Baudrate Maximum length of the bus

1 Mbit/s 25 m

500 kbit/s 100 m

250 kbit/s 250 m

125 kbit/s 500 m

100 kbit/s 1000 m

50 kbit/s 1000 m

Note THE NEW DAILY (MY 2014) supports 250 kbit/s. Slower Baudrate can be developed by IVECO upon the specific request by theClient.

Object dictionary (OD)

The central concept of CANOpen is based on the use of an Object Dictionary that collects data on the communication and applic-ation. Each object in the dictionary can be addressed using a 16-bit index and an 8-bit sub-index.

The arrangement of the Object Dictionary is as follows:

Table 4Index (hexadecimal) Subject

0000 Not used

0001-001F Static Data Types

0020-003F Complex Data Types

0040-005F Manufacturer Specific Data Types

0060-007F Device Profile Specific Static Data Types

0080-009F Device Profile Specific Complex Data Types

00A0-0FFF Reserved for future uses

1000-1FFF Communication Profile Area

2000-5FFF Manufacturer Specific Profile Area


3.3 CANOpen7

— Printed 603.95.827 – 1 Ed. - Base 02/2014

Index (hexadecimal) Subject

6000-9FFF Standardised Device Profile Area

A000-FFFF Reserved for future uses

As you can see from the table, four segments can be distinguished in the OD:

● addresses lower than 1000 specify Data Types;● indexes between 1000 and 1FFF describe the Communication Profile Area, which contains communication parameters

common to all devices● indexes between 2000 and 5FFF include the Manufacturer Specific Profile Area, used by the manufacturers to extend

the basic set of the device functions;● indexes between 6000 and 9FFF address the Standardised Device Profile Area, which describes all aspects relating to a

specific devise category. All devices of the same type must behave in the same manner.

More detailed descriptions of individual Data Types are given below:

● static Data Types are defined standard types such as Boolean logic, integers, floating points, strings etc. These objects arecommon to all devices and cannot therefore be read or written;

● Complex Data Types are predefined structures, consisting of standard data types common to all devices● Manufacturer Data Types are predefined structures, consisting of standard data types but differ from complex data types

because they relate to a specific device● Device Profiles can define further Data Types specific to their devices. In particular, static data types are defined by profiles

included between indexes 0060 and 007F, while complex data types fall between 0080 and 009F.

The object dictionary is made up of six columns as follows:

Index Object Name Type Attribute M/O

where:

● Index indicates a position in the dictionary;● Object indicates the symbolic name of the object (e.g. DOMAIN, VAR, ARRAY, RECORD)● Name contains a textual description;● Type indicates the data type (e.g. BOOLEAN, UNSIGNED8, SIGNED16);● Attribute indicates the type of access from the bus to the device (e.g. Read/Write, ReadOnly, WriteOnly);● M/O stands for Mandatory or Optional.

Two mechanisms are available for accessing the above data and these are described below.

3.3 CANOpen

Communication model

Although the CAN is multi-master type, the implementation of CANOpen requires a hierarchical master-slave type structuresin order to simplify system configuration and network management. This means that despite the continued existence of a CANfield- bus in which each node remains a master to all intents and purposes at Physical Layer and Data Link Layer, the link with theApplication Layer requires the selection of an Application Master for each of the services provided. The same node may be themaster for various functions, or there may be many different masters. It is also possible to change the master, even at each systemcycle, according to the programmed master section algorithm (for example: the master for this service must be the node currentlywith the lowest ID amongst the Active Error nodes. It does not go without saying, and is actually unlikely, that the same station willalways satisfy the required characteristics at each cycle, either because it may become faulty and enter active Passive Error statusor because another node with a lower ID may start operating correctly began, switching to Active Error node. In any case, thishierarchy is fully transparent to lower layers.

Each master can have up two 127 slaves: Each node is identified by means of a unique 7 bit address (ID), within a range from 1 to127.

Note In the IVECO application, only one master and a single slave are used.

COB-ID communication objects

The CANOpen exchanges information via Communication Objects (COB): the CANOpen communication model specifies thevarious COBs, the communication services and the possible data transmission trigger modes. Each COB (communication object) isidentified unequivocally by an identifier that is part of the COB. The CAN 2.0A specification supports up to 2048 COBs, identifiedby means of 11 or 29 bit long identifiers.

Synchronous and asynchronous message transmission is supported. The former indicate that it is possible to acquire and implementinformation in a coordinated manner throughout the network. The predefined Communication Objects that are dedicated to thismessage type are known as Sync Message and Time Stamp Message. Conversely, asynchronous messages may be sent at any timebecause they do not need to respect any predefined synchronisation within the entire network.

The following table shows the predefined identifier CANOpen allocation system.

1) The OD index for Tx and Rx PDOs depends on a number of actuation objects in the actuation group. Each additional actuation objectbegins with a description with an offset of 40 hex. For example: OD index for the first actuation object begins with TPDOs with 1800 hex


3.3 CANOpen9

— Printed 603.95.827 – 1 Ed. - Base 02/2014

and RPDOs with 1400 hex, each additional actuation object begins with an offset of 40 hex -> 1840 hex and 1440 hex for the secondactuation object, etc.2) These COB-IDs are pre-set.

Network control objects (NMT, SYNC etc.) have the highest priority, followed by the PDOs and then by the SDOs; the priorityis established in "AND wired mode" on the bus layers at the time of transmission of the identifier (Carrier Sense Multiple Access /Collision Detection) in which the lower layer (dominant) takes precedence over the higher layer (recessive).

Service Data Objects (SDO)

The Service Data Objects (SDO) allow access to the OD objects of all nodes, which can be configured in this way. Because thecommunication does not take place in real time, the priority of the SDOs is less than that of the PDOs, but of peer-to-peer type(not multicast). Each device can support more than a single SDO (a single SDO is the default).

The COB-IDs for SDO communication are:

● from master to slave: 600h + Node-ID;● from slave to master: 580h + Node-ID.

Process Data Objects (PDO)

Data are exchanged in real time through Process Data Objects (PDO). PDOs correspond to objects in the OD of a device and areresponsible for the interface with application objects.

Each Process Data Object is mapped exactly on one CAN frame so that they can be changed quickly without problems: The directconsequence is that the amount of data that can be transmitted via a PDO cannot exceed 8 bytes.

Transmitted PDOs are termed Transmit-PDO (T_PDO), while received PDOs are termed Receive-PDO (R_PDO).

Transmission mode

PDOs our cent from one device (PRODUCER) to another device (CONSUMER), or to many other devices (broadcasting),without a confirmation request. Each node in the network can listen to the message and decide individually whether to accept it ornot by means of Acceptance Filtering.

For each typical CANOpen node, it is possible to define up to four Receive PDOs (from the Application Master to the device) andfour Transmit PDOs (from the device to the Application Master). THE NEW DAILY (MY 2014) supports up to 30 TPDO and upto 20 RPDO. In particular, the transmission of Process Data Objects by a slave node may be triggered by means of certain localevents that affect the node or by means of a remote request from the master.

Synchronization of the device is made possible by a specific synchronization object, the SYNC Object (see Paragraph: PredefinedCommunication Objects), sent out periodically.

The transmission modes can be: synchronous or asynchronous.

The following figure 1 shows the principle of synchronism and asynchronism: Synchronous PDOs are sent within a predefinedtime window, immediately behind the SYNC Object, while asynchronous PDOs do not have any relationship with this window andtherefore with the SYNC Object.

Predefined communication objects

Predefined communication objects are sub-divided into three categories:

● SYNC Object● Time Stamp Object● Emergency Object

These perform an important role even though their implementation is optional.

SYNC Object

The SYNC is sent periodically to all application devices (SYNC Slave) from the synchronisation device (SYNC Master). This scansthe basic network clock and the time elapsing between one SYNC object and another is defined by the standard parameter Com-munication Cycle Period, that may be written through a configuration algorithm during the node built-up process. A jitter time mayoccur during transmission, corresponding approximately to latency due to some other message sent immediately before the SYNC.

To ensure fast access to the bus, the priority attached to the SYNC Object is very high: Nodes that work in synchronous manner,use the SYNC to adjust their timing with that of the synchronization device. The relative details depend on the individual slave.

Time Stamp Object

The Time Stamp Object is not supported by the Expansion Module of the NEW DAILY (MY 2014).

Emergency Object

Emergency Objects are sent by a device that becomes aware of an internal error situation, to all other devices, with the highestpossible priority. A single emergency object may be transmitted for each error event in order not to block the traffic due to notify-ing of the same fault more than once.

Network management (NMT service)

Network management is carried out on the nodes and follows a master-slave structure. NMT imposes the use of one master at atime during start-up/execution.

NMT services allow the nodes to be initialised, started, monitored, reset or stopped.

Note If the device connected to the CANOpen network does not follow the instructions given in the paragraph below, the applicationshould be agreed with IVECO.

Figure 2 shows the status diagram of a CANOpen node. Table 8 lists all the NMT services available for controlling status steps.

126276 Figure 2

Status diagram of a CANOpen node

Note Only SDO communication is possible in Pre-Operational status, whereas PDO is blocked.

PDO communication also takes place in Operational status.

The default setting is such that the EM of the NEW DAILY (MY 2014) automatically launches the NMT Operational status afterK15.

(9), (10), (11) Reset_Node command (CS = 129)

(12), (13), (14) Reset_Communication command (CS = 130)

As specified in the CANOpen Communication Profile, four main statuses are defined:

● Initialisation or Boot-up;● Pre-Operational;● Operational;● Stopped.

Initialisation status (or Boot-up) is automatically reached after ignition and also after a reset command (node or communication).Once initialisation is complete, the node enters Pre-Operational mode independently.

In Pre-Operational status, it is possible to carry out parameterisation and ID allocation. SDO communication and emergency mes-sages are also permitted. The device may also be switched in Operational status.

In operational status, the node is able to communicate actively and the use of all types of CAN messages is permitted. The devicecan carry out the movement specified for the application.

At any moment during operation, the NMT master can force the device to stopped status.

The NMT services perform the following functions:

● Start Remote Node:Command for changing over from Pre-Operational status to Operational. The actuation is able to send and receive processdata only in Operational status.

● Stop Remote Node:Command for changing from Pre-Operational to Stopped or from Operational to Stopped. In Stopped status, the node canonly process NMT commands.

● Enter Pre Operational:command for changing from Operational to Stopped or Pre-Operational. In Pre-Operational status, the node cannot processPDOs. It may, however, be parameterised or controlled by means of SDOs. This means that it is also possible to set referencevalues.

● Reset Node:command for changing from Operational, Pre-Operational or Stopped to Initialisation. After the Reset Node command, allobjects (1000 hex - 9FFF hex) are reset.

● Reset Communication:command for changing from Operational, Pre-Operational or Stopped to Initialisation. After the Reset Communication com-mand, all communication objects (1000 hex - 1FFF hex) are reset this to their original status.

Note The NMT is described in detail in the CANOpen standard "CiA DS-301 V4.01 (Application Layer and Communication Profile)".

Heartbeat

CANOpen offers two alternatives for guaranteeing network operation:

● Node Guarding;● Automatic transmission of a Heartbeat message by network nodes.

Only the Heartbeat message is implemented in the Expansion Module.

A node uses the Heartbeat to automatically transmit its communication status at regular intervals as evidence of its communicationcapability. The period between two Heartbeat messages can be configured by IVECO Customer Service on request of the User.

IVECO instructions for vehicle CANOpen network and CANOpen communication

Note At the time of the key OFF/key ON transition, the Bodybuilder control unit which interfaces with the Expansion Modulevia the CANOpen should be connected to the connected and should start communicating as quickly as possible(within a maximum time of 2 seconds).

Note The Bodybuilder should fit two 120 Ohm termination resistances on their wiring for the CANOpen network between BB_CAN_Hand BB_CAN_L in order to allow communication between their control unit and the Expansion Module. The terminations must beinserted on both ends of the network.

The Bodybuilder device should never be physically disconnected from the CANOpen network after the key ON.

If these instructions are not followed, the correct CANOpen communication by the Expansion Module cannot be guaranteed.

CANOpen objects and CAN messages available for the Bodybuilder

Using CANOpen the Bodybuilder can have vehicle information through:

● CANOpen objects (DSP 413-3 and DSP 413-5 objects and Producer specific objects);● CAN messages via gateway on CANOpen (objects DSP 413-6).

The CAN messages are enabled at IVECO Customer Service facilities. Different communication settings are available. For informa-tion, see the website www.ibb.iveco.com.

No specific application is needed by Engineering.

Listed below are all the CANOpen objects available for the Bodybuilder.

For details of each object, refer to the following standards:

● CiA DS- 413-3 V2.2 (Device profile for truck gateways Part 3: Other than brake and running gear devices);● CiA DS- 413-5 V1.0.2 (Device profile for truck gateways Part 5: Superstructure objects);● CiA DS- 413-6 V1.0.2 (Device profile for truck gateways Part 6: Framework for J1939-based networks).

For resolutions, ranges and offsets of the various objects, refer to standard ISO11992-3.

For the composition of CAN messages by CiA DS 413-6 refer to standard SAEJ1939-71.

Description of functions settable by the Bodybuilder

This paragraph describes the functions and properties of the operating modes available with the Expansion Module CANOpenmode.

Note A specific application from Engineering is needed to enable the following items. The requests should be sent to IVECO CustomerService (office: Workshop Methods and Diagnostics).

The CANOpen function is able to manage several operating modes, each of which satisfies given applications:

● PTO engagement/release request;● PTO engagement/release enablement;● Engine control requests:

■ Torque Mode, which is only for the torque limit (the torque control is not carried out),■ Engine Mode, which carries out the rpm check (this mode is not available on CNG engines),■ Limit Mode, which carries out the check applying the maximum rpm limit (this mode is not available on CNG engines),■ Speed Mode, which carries out the speed check (this mode is not available on CNG engines).

PTO engagement/release request

It is possible to request PTO engagement and release from the CANOpen. The request is coded as follows:

● 00b = PTO not requested;● 01b = PTO requested;● 10b = Error;● 11b = Not available.

In this way it is possible to obtain different PTO engagement/release requests from:

1. button on the dashboard:■ PTO 1 switch status,■ PTO 2 switch status;

2. CANOpen (via CANOpen DSP413-3):■ First clutch dependent PTO switch (object 6136H),■ Second clutch dependent PTO switch (object 6137H),■ Clutch independent PTO switch (object 6138H),■ First engine mounted PTO switch (object 6139H),■ Second engine mounted PTO switch (object 613AH),■ Transmission output shaft PTO switch (object 61A3H),■ Transfer case output shaft PTO switch (object 61A4H).

If PTO engagement or release is requested by means of the button or CANOpen, the system behaves as follows:

Table 15

No request (11b) OFF ON OFF


3.3 CANOpen

— Printed 603.95.827 – 1 Ed. - Base 02/2014

Note The engagement/disengagement requests from the CANOpen take priority over the requests made using the button. If you wish touse the button only, the value 3 (11b) must be assigned to the CANOpen request or not available.

Note If the PTO is engaged via the CANOpen, Engagement Restriction is present and this restriction must be removed and the controlset from the CANOpen; later on it is possible to make a new request. If the restriction is removed but the control not reset, the PTOremains switched off.

Feedback

Feedback is a signal that indicates whether the PTO is actually engaged. The feedback status on the type of PTO used is sent viaCANOpen (DSP413-3):

● First clutch dependent PTO feedback (object 612EH),● Second clutch dependent PTO feedback (object 612FH),● Clutch independent PTO feedback (object 6130H),● First engine mounted PTO feedback (object 6131H),● Second engine mounted PTO feedback (object 6132H),● Transmission output shaft PTO feedback (object 61A0H),● Transfer case output shaft PTO feedback (object 61A1H),● At least one PTO engaged (subject 61A2H).

PTO engagement/release enablement

PTO engagement/for release enablement allows the user to be able to agree on enablement or not after making a request fromthe button on the dashboard or via CANOpen.

The engage/disengage consent procedure is as follows:

1. when user decides to engage (release) the PTO, they make a request from a switch (button for PTO1 and switches forPTO2) or from CANOpen;

2. once the Expansion Module receives the engagement (release) request, it asks the user for enablement to engage (release)the PTO. This takes place by setting one or more (according to the type of PTO) of the following CANOpen objects (61A5H,61A6H, 61A7H, 61A8H, 61A9H, 61AAH, 61ABH) to a value of 1:■ object(s) = 1 → enablement request,■ • object(s) = 0 → no request

3. the user can now decide if to give or deny consent for the required operation (engage or disengage). The user’s responsetakes place by setting one or more of the following CANOpen objects (61ACH, 61ADH, 61AEH, 61AFH, 61B0H, 61B1H,61B2H). If the subject is set at 0 the consumer denies the enablement and the PTO is not engaged. Conversely, if the subjectis set at 1, the EM interprets this value as a go ahead for engagement:■ object(s) = 1 → enablement agreed,■ object(s) = 0 → enablement denied;

4. according to type of enablement received by the user, the Expansion Module acts accordingly:■ enablement received = 1 → the PTO will be engaged (released),■ enablement received = 0 → no operation will be carried out and PTO status will remain unchanged.

If the user does not send any type of enablement to the Expansion Module within a given time period, no operation will be carriedout and PTO status will remain unchanged. The default value of the timeout on engagement or release is equal to 3 seconds.

The following figure shows the sequence for the PTO enablement/release procedure.

Note In order to use this function, IVECO Customer Service must enable the parameter:

PTO[x]_ISOconsentBBcfg

in which, for each type of PTO installed, consent via CANOpen is enabled

Note If the enablement is removed with the PTO engaged, the EM switches off.

For requesting enablement from the Expansion Module to the user are:

● First clutch dependent PTO engagement consent (object 61A5H);● Second clutch dependent PTO engagement consent (object 61A6H);● Clutch independent PTO engagement consent (object 61A7H);● First engine mounted PTO engagement consent (object 61A8H);● Second engine mounted PTO engagement consent (object 61A9H);

— Printed 603.95.827 – 1 Ed. - Base 02/2014

● Transmission output shaft PTO engagement consent (object 61AAH);● Transfer case output shaft PTO engagement consent (object 61ABH).

Objects to be used for the user’s response to the enablement request are:

● First clutch dependent PTO engagement consent - By Bodybuilder (object 61ACH);● Second clutch dependent PTO engagement consent - By Bodybuilder (object 61ADH);● Clutch independent PTO engagement consent - By Bodybuilder (object 61AEH);● First engine mounted PTO engagement consent - By Bodybuilder (object 61AFH);● Second engine mounted PTO engagement consent - By Bodybuilder (object 61B0H);● Transmission output shaft PTO engagement consent - By Bodybuilder (object 61B1H)● Transfer case output shaft PTO engagement consent - By Bodybuilder (object 61B2H).

Engine control requests

The engine may be controlled in different ways by means of the CANOpen module:

● RPM request (not available on CNG engines);● configuration of maximum RPM limit (not available on CNG engines);● torque request (not available on CNG engines);● maximum vehicle speed configuration (not available on CNG engines).

Engine control ends when the PTO is released.

For management of the engine control requests either via CANOpen or using the button, refer to paragraph: "Multiple requestmanagement / priorities".

Note A specific application from Engineering is needed to enable these functions.


Restrictions on engine control

It is possible to associate two types of restriction for each engine control request:

● Request restrictions (RR):Before servicing the request, the EM evaluates any request restrictions. If no restrictions have been configured, or if the re-strictions have been exceeded, the EM services the request. Otherwise the requests will not be applied to the engine.

● Shutoff conditions (RS):Once the control has been applied to the engine, the EM assesses any shutoff (stop) conditions. The conditions are evaluatedfor as long as the engine control is active. If the shutoff condition has occurred, the engine control is interrupted.

If more than one condition is enabled for a certain engine request, the request may be serviced if and only if all configured condi-tions are exceeded.

Request restriction conditions are treated as such only if their time duration is greater than or equal to a time defined by para-meter EEC_[service]_RRtimeout (parameter configurable by IVECO Customer Service).

Engine control stop requests are treated as such only if their time duration is greater than or equal to a time defined by parameterEEC_[service]_RStimeout (parameter configurable by IVECO Customer Service).

In the event of multiple control requests, refer to paragraph: "Multiple request management / priorities".

For each type of engine control request, the same set of conditions is always available for both restriction requests (RR) andshutoff requests (RS).

A full list of possible conditions to be activated is given in the following table.

Table 16List of possible conditions on restriction requests/shutoff requests

Condition ID condition

Service brake pressed RR/RS 01

Service brake not pressed RR/RS 02

Clutch pedal pressed RR/RS 05

Clutch pedal not pressed RR/RS 06

Gear not in neutral (*) RR/RS 07

Reverse RR/RS 08

Idling RPM RR/RS 17

Max engine rpm RR/RS 18

(*) only for automatic gearbox

Note No condition is enabled by default.

RPM request/maximum rpm limit

An rpm request may be made by adjusting the CANOpen object:

● Requested engine speed (object 614AH).

The maximum rpm limit may be configured by adjusting the CANOpen object:

● Requested engine speed upper limit (object 6140H).

Note If the PTO is not stationary, the rpm control is not carried out.

Note A specific application from Engineering is needed to enable these functions. The requests should be sent to IVECO Customer Ser-vice (office: Workshop Methods and Diagnostics).

The results of controls on individual restrictions are shown in the following objects:

● Maximum rpm limit: Engine speed control upper limit allowed (object 6337H);● RPM request: Engine speed control allowed (6339H).

Values assumed by the objects are coded as follows:

● 00b = Control not allowed;● 01b = Control allowed;● 10b = Error;● 11b = Not available.

All active requests are considered valid. For their management, refer to the paragraph: "Multiple request management / priorities".

Maximum torque limit request

It is possible to perform a maximum torque limit request acting on a CANOpen object only if no rpm or maximum limit request isalready present.

● Engine torque limit request (subject 6144H).

The request is expressed as a percentage, i.e. between 0 and 100%

Note This function is not applicable to CNG engines.

Note A specific application from Engineering is needed to enable these functions. The requests should be sent to IVECO Customer Ser-vice (Workshop Methods and Diagnostics office).

Maximum vehicle speed configuration

It is possible to make a torque request acting on the CANOpen object:

● Requested vehicle speed limit (object 6146H).

Note This function is not applicable to CNG engines.

Note A specific application from Engineering is needed to enable these functions. The requests should be sent to IVECO Customer Ser-vice (office: Workshop Methods and Diagnostics)

● Vehicle speed limit control allowed (633CH).




Multiple request management/Priorities

The following strategy will be followed in the event of multiple engine control requests:

● button-linked engine control requests take priority over requests carried out from CANOpen;● RPM control takes priority over torque control;● if priorities are equal (rpm requests from CANOpen), the minimum value of the two requests (rpm request and rpm limit) is

accepted.

Note If the PTO is not stationary, the rpm control is not carried out.

Wiring Diagram

For effective and correct use by Bodybuilder, IVECO has arranged specific connection points to be used for the added systems.

Such points have been provided to rule out any additions to or adaptations of the basic design in order to ensure operational integ-rity and thus maintenance of the warranty.
