1 Application and Scope

The P63x differential protection devices are designed for the fast and selective short-circuit protection of transformers, motors and generators and of other two-, three- orfour-winding end arrangements.

The MiCOM P63x range features fast three-stage differential protection by applying atripping characteristic with two knee points and two high value settable differentialcurrent thresholds to enable rapid tripping in conjunction with inrush, overfluxing andthrough-stabilization. Amplitude and vector group matching is made by just entering thenominal values of each transformer end and the associated current transformers.A new (optional) overreaching current measuring circuit monitoring function will preventunwanted tripping by differential protection for faults in the CT's secondary circuit.

When considering 1 circuit breaker arrangements and ring busbar arrangements it isalso possible to define a virtual end, where phase currents and the residual current fromtwo freely-selectable ends may be added geometrically (vector sum).

A phase reversal function is available for applications in pumped storage power stations.

In a device type where protection functions are available more than once they may eachbe freely assigned to individual winding ends.

Moreover there are numerous backup protection and automatic control functionsavailable.

The relevant protection parameters can be stored in four independent parametersubsets in order to adapt the protection device to different operating and power systemmanagement conditions.

General functionsGeneral functions are complete function groups, which may be individually configured orcancelled, depending on the application (e.g. included in or excluded from the devicesconfiguration).An exception is the MA I N function, which is always visible.

A function is selected by a mouse click in the support software:

Unused or cancelled function groups are hidden to the user, thus simplifying the menu.

Communication functions and measured value functions may also be configured orexcluded.

This concept provides a wide choice of functions and makes wide-ranging application ofthe protection device possible, with just one model version. On the other hand simpleand clear parameter settings and adaptations to each protection scheme can be made.The powerful programmable logic provided by the protection device also makes itpossible to accommodate special applications.

DesignThe MiCOM P631, P632, P633 and P634 protection devices are modular in design.The plug-in modules are housed in a robust aluminum case and electricallyinterconnected via one analog p/c board and one digital p/c board.

Inputs and outputsThe nominal current and voltage values of the measuring inputs on the P63x can be setwith the function parameters.

The nominal voltage range of the optical coupler inputs is 24 to 250 V DC. As an optionbinary signal input modules with a higher operate threshold are available.

The auxiliary voltage input for the power supply is also designed for an extended range.

The nominal voltage ranges are 48 to 250 V DC and 100 to 230 V AC. A 24 VDCversion is also available.

All output relays can be utilized for signaling and command purposes.

The optional PT 100 input is lead-compensated, balanced and linearized for PT 100resistance thermometers as per IEC 751.

The optional 0 to 20 mA input provides open-circuit and overload monitoring, zerosuppression defined by a setting, plus the option of linearizing the input variable via20 adjustable interpolation points.

Two selectable measured values (cyclically updated measured operating data andstored measured fault data) can be output as a burden-independent direct current viathe two optional 0 to 20 mA outputs. The characteristics are defined via 3 adjustableinterpolation points allowing a minimum output current (4 mA, for example) for slave-sideopen-circuit monitoring, knee-point definition for fine scaling, and a limitation to lowernominal currents (10 mA, for example). Where sufficient output relays are available,a selectable measured value can be output in BCD-coded form by contacts.

The following equation is used to calculate the specifications of a current transformer forthe offset maximum primary current:

( ) ( ) ' max1,iopnominomsat IkRRInRRV ++=

with:Vsat: saturation voltage (IEC knee point)

I'1,max: non-offset maximum primary current, converted to the secondary side

Inom: rated secondary current

n: rated overcurrent factor

k: over-dimensioning factorRnom: rated burden

Rop actual connected operating burden

Ri internal burden

The specifications of a current transformer can then be calculated for the minimumrequired saturation voltage Vsat as follows:

( ) ' max1,iopsat IkRRV +

As an alternative, the specifications of a current transformer can also be calculated forthe minimum required rated overcurrent factor n by specifying a rated power P

Theoretically, the specifications of the current transformer could be calculated for lack ofsaturation by inserting instead of the required over-dimensioning factor k its maximumvalue:

k Tmax +1 1

with: : system angular frequencyT1: system time constant

7/15/2019 Vol1 P632-635

40/605



However, this is not necessary. Instead, it is sufficient to calculate the over-dimensioning factor k such that the normal behavior of the analyzed protective functionis guaranteed under the given conditions.

The transformer differential protection device is equipped with a saturation discriminator.This function will generate a stabilizing blocking signal if a differential current occurs as aconsequence of transformer saturation with an external fault (in contrast to an internalfault). For the passing maximum fault current in the case of an external fault,overdimensioning is, therefore, obviated.

For the maximum fault current with an internal fault, static saturation up to a maximumsaturation factor fS of 4 is permissible. This corresponds to an overdimensioning

factor k of 0.25.

The implementation of these requirements is comparatively unproblematic astransformer differential protection would require overdimensioning in accordance with thetotal fault clearing time, which includes the total circuit-breaker open time for an externalfault.

Current transformers should observe the error limit values for class 5P.

3 Operation

3.1 Modular Struc ture

The P63x, a numeric device, is part of the MiCOM P 30 family of devices. The devicetypes included in this family are built from identical uniform hardware modules.Figure 3-1 shows the basic hardware structure of the P63x.

3-1 Basic hardware structure

7/15/2019 Vol1 P632-635

42/605

3 Operation(continued)


The external analog and binary quantities electrically isolated are converted to theinternal processing levels by the peripheral modules T, Y, and X. Commands andsignals internally generated by the device are connected to the external plant viacontacts through the binary I/O modules X. The external auxiliary voltage is applied tothe power supply module V, which supplies the auxiliary voltages that are requiredinternally.

Analog data is transferred from the transformer module T via the analog bus module B tothe processor module P. The processor module contains all the elements necessary forthe conversion of measured analog variables, including multiplexers and analog/digitalconverters. The analog data conditioned by the analog I/O module Y is transferred tothe processor module P via the digital bus module. Binary signals are fed to theprocessor module by the binary I/O modules X via the digital bus module.

The processor handles the processing of digitized analog variables and of binary signals,generates the protective trip and signals, and transfers them to the binary I/O modules Xvia the digital bus module. The processor module also handles overall devicecommunication. As an option, communication module A can be mounted on theprocessor module to provide serial communication with substation control systems.

The control and display elements of the integrated local control panel and the integratedPC interface are housed on control module L.

3.2 Operator-Machine Communication

The following interfaces are available for the exchange of information between the userand the device:

Integrated local control panel (LOC)

PC interface

Communication interface

All settings and signals as well as all measurements and control functions are arrangedwithin the branches of the menu tree following a scheme that is uniform throughout thedevice family. The main branches are:

Parameters branchAll settings are contained in this branch. This branch carries all settings, including thedevice identification data, the configuration parameters for adapting the device interfacesto the system, and the function parameters for adapting the device functions to theprocess. All values in this group are stored in non-volatile memory, which means thatthe values will be preserved even if the power supply fails.

Operation branchThis branch includes all information relevant for operation such as measured operatingdata and binary signal states. This information is updated periodically and consequentlyis not stored. In addition, various controls are grouped here, for example those forresetting counters, memories and displays.

Events branchThe third branch is reserved for the recording of events. All information in this group istherefore stored. In particular, the start/end signals during a fault, the measured faultdata, and the sampled fault waveforms are stored here and can be read out whenrequired.

Settings and signals are displayed either in plain text or as addresses, in accordancewith the users choice. Chapters 7, 8 and 10 describe the settings, signals andmeasured values available with the P63x. The possible setting values can be found inthe P63x's data model file associated with the PC operating program (MiCOM S1).

The configuration of the local control panel also permits the installation of MeasuredValue 'Panels on the LCD display. Different Panels are automatically displayed forspecific system operating conditions. Priority increases from normal operation tooperation under overload conditions and finally to operation following a short circuit inthe system. Thus the P63x provides the measured data relevant for the prevailingconditions.

44/605



3.3 Configuration of the Measured Value Panels (Function Group LOC)

The P63x offers Measured Value Panels, which display the measured values relevant ata given time.

During normal power system operation, the Operation Panel is displayed. As an eventoccurs, the display switches to the appropriate Event Panel - provided that measuredvalues have been selected for the Event Panels. In the event of overload event, thedisplay will automatically switch to the Operation Panel at the end of the event. In theevent of a fault, the Fault Panel remains active until the LED indicators or the faultmemories are reset.

Operation Panel

The Operation Panel is displayed after the set return time has elapsed, provided that atleast one measured value has been configured.

The user can select which of the measured operating values will be displayed on theOperation Panel by means of an m out of n parameter. If more measured values areselected for display than the LC display can accommodate, then the display will switch tothe next set of values at intervals defined by the setting at LOC: Hold-Time forPanels or when the appropriate key on the local control panel is pressed.

Fault panelThe Fault Panel is displayed in place of another data panel when there is a fault,provided that at least one measured value has been configured. The Fault Panelremains on display until the LED indicators or the fault memories are cleared.

The user can select the measured fault values that will be displayed on the Fault Panelby setting an 'm out of n' parameter. If more measured values are selected for displaythan the LC display can accommodate, then the display will switch to the next set ofvalues at intervals defined by the setting at LO C: Hol d- Ti me for Pa ne ls or whenthe appropriate key on the local control panel is pressed.

Overload PanelThe Overload Panel is automatically displayed in place of another data panel when thereis an overload, provided that at least one measured value has been configured.The Overload Panel remains on display until the overload ends, unless a fault occurs.In this case the display switches to the Fault Panel.

The user can select the measured values that will be displayed on the Overload Panelby setting a 'm out of n' parameter. If more measured values are selected for displaythan the LC display can accommodate, then the display will switch to the next set ofvalues at intervals defined by the setting at LO C: Hol d- Tim e fo r Pan el s or whenthe appropriate key on the local control panel is pressed.

3.4.4 UCA2 Communication Interface (Funct ion Group UCA2)

This function group is available only with the P63x -604/-605/-606 device.

(As of device version P63x 610, the IEC 61850 communication interface is available:it uses function groups IEC, GOOSE and GSSE. A description is provided in thefollowing section).

The communication protocol Utility Communication Architecture 2.0 is implemented withthe UCA2 function group and the Ethernet module (in the 10 MHz and 100 MHzvariants).

Function group UCA2 is only available as an alternative to function group COMM1

(hardware ordering option!). Pending the implementation of the IEC 61850 protocol,the use of UCA2 is reserved for specific projects.

The UCA2 addresses for setting, information and control functions are described inchapters 7 and 8.

(See also the detailed description of the UCA2 protocol implementation:P54x_EN_UC_B42.pdf).

3.4.5 IEC 61850 Communication Interface(Function groups IEC, GOOSE and GSSE)

These function groups are available only with the P63x -610 device.

The IEC 61850 communication protocol is implemented by these function groups and theEthernet module.

Note:

Function group IEC is only available as an alternative to function group COMM1(hardware ordering option!).

3.4.5.1 IEC 61850 Communication Interface (Function Group IEC)

IEC 61850IEC 61850 was created jointly by users and manufacturers as an international standard.The main target of IEC 61850 is interoperability of devices. This includes the capabilityof two or more intelligent electronic devices (IED), manufactured by the same companyor different companies, to exchange data for combined operation.

Now this new communication standard IEC 61850 has created an open and commonbasis for communication from the process control level down to the network control level,for the exchange of signals, data, measured values and commands.

For a standardized description of all information and services available in a field device adata model, which lists all visible functions, is created. Such a data model, specificallycreated for each device, is used as a basis for an exchange of data between the devices

and all process control installations interested in such information. In order to facilitateengineering at the process control level a standardized description file of the device,based on XML, is created with the help of the data model. This file can be imported andprocessed further by the relevant configuration program used by the process controldevice. This makes possible an automated creation of process variables, substationsand signal images.

The following documentation with the description of the IEC 61850 data model, used withthe P63x, is available:

IDC file based on XML in the SCL (Substation Configuration Description Language)with a description of data, properties and services, available from the device, that areto be imported into the system configurator.

PICS_MICS_ADL file with the following contents:

PICS (Protocol Implementation Conformance Statement) with an overview ofavailable services.

MICS (Model Implementation Conformance Statement) with an overview ofavailable object types.

ADL (Address Assignment List) with an overview of the assignment of parameteraddresses (signals, measuring values, commands, etc.) used by the device withthe device data model as per IEC 61850.

Ethernet ModuleThe optional Ethernet module provides an RJ45 connection and a fiber optic interfacewhere an Ethernet network can be connected. The selection which of the two interfacesis to be used to connect to the Ethernet network is made by setting the parameterI E C : E t h e rn e t m e d i a . The optical interface of the Ethernet module is currentlyavailable with an SC connector (100 Mbit/s and 1300 nm). A variant with an STconnector is being developed. The RJ45 connector supports 10 Mbit/s and 100 Mbit/s.

The optional Ethernet module additionally provides an RS485 interface for remoteaccess with the operating program MiCOM S1 (function group COMM2).

Notes: The P63xmay only be equipped with theoptional Ethernet module as analternative to the standard optional communication module. Therefore theEthernet based communication protocol IEC 61850 is only available as an

alternative to function group COMM1.

The Ethernet module can only be applied in conjunction with the processormodule P (included in current hardware version) with the item number 9650135 or other processor modules available in the near future. When upgradingolder P63x hardware versions with an Ethernet module, which is technicallypossible, it must be kept in mind that such units are usually equipped with theprocessor module P, item number 0337 875. But this processor module Pdoes not support the Ethernet module and therefore the communicationsprotocol per IEC 61850 is also not supported. If such an upgrade is carriedout the processor module P must be exchanged. The processor module itemnumber can be checked by reading the device identification setting atD V I C E : M o d u l e v a r . s l o t 1 .

Activating and EnablingThe IEC function group can be activated by setting the parameter I E C : Fu n c t i o ng r o up I EC . This parameter is only visible if the optional Ethernet communicationmodule is fitted to the device. After activation of IEC, all data points associated with thisfunction group (setting parameters, binary state signals etc.) become visible.The function can then be enabled or disabled by settingI E C : G e n e ra l e n a b l e U S E R .

The parameter settings for function groups IEC, GOOSE and GSSE in the device are notautomatically activated. Activation occurs either when the command I E C : E n ab l ec o n f i gu r a t i o n is executed or automatically when the device is switched online atM A I N : D e v i c e o n - l i n e .

Client Log-onCommunication in Ethernet no longer occurs in a restrictive master slave system, as iscommon with other protocols. Instead server or client functionalities, as defined in the'Abstract Communication Service Interface' (ACSI, IEC 61870-7-2), are assigned to thedevices. A 'server' is always that device which provides information to other devices.A client may log-on to this server so as to receive information, for instance 'reports'.In a network a server can supply any number of clients with spontaneous or cyclicinformation.

In its function as server the P63x can supply up to 16 clients with information.

Clock SynchronizationWith IEC 61850 clock synchronization occurs via the SNTP protocol, defined as standardfor Ethernet. Here the P63x functions as a SNTP client.

For clock synchronization one can select between the operating modes Broadcast fromSNTP Server orRequest from Server. With the first operating mode synchronizationoccurs by a broadcast message sent from the SNTP server to all devices in the network,and in the second operating mode the P63x requests the device specific time signalduring a settable cycle.

Fault TransmissionTransmission of fault files is supported per "File Transfer".

Transmission of "Goose

Messages" The so-called "Goose Message" is a particular form of data transmission. Whereasnormal server-client-services are transmitted at the MMS and TCP/IP level, the "GooseMessage" is transmitted directly at the Ethernet level with a high transmission priority.Furthermore these "Goose Messages" can be received by all participants in therespective sub-network, independent of their server or client function. In IEC 61850"Goose Messages" are applied for the accelerated transmission of information betweentwo or more devices. Application fields are, for example, a reverse interlocking, a transfertrip or a decentralized substation interlock. In future the "Goose Message" will thereforereplace a wired or serial protective interface.

According to IEC 61850 there are two types of "Goose Messages", GSSE andIEC-GOOSE. The GSSE is used to transmit binary information with a simpleconfiguration by 'bit pairs', and it is compatible with UCA2. However IEC-GOOSE

enables transmission of all data formats available in the data model, such as binaryinformation, integer values or even analog measured values. But this will require moreextensive configuration with the help of the data model from the field unit situated on theopposite side. With IEC-GOOSE the P63x at this time supports sending and receiving ofbinary information.

Communication with theOperating ProgramMiCOM S1 via the EthernetInterface

Direct access by the operating program MiCOM S1 via the Ethernet interface on thedevice may occur through the "tunneling principle". Transmission is carried out by anEthernet Standard Protocol, but this is only supported by the associated operating

program MiCOM S1 (specific manufacturer solution). Such transmission isaccomplished over the same hardware for the network, which is used for server-clientcommunication and "Goose Messages".Available are all the familiar functions offered by the operating program MiCOM S1 suchas reading/writing of setting parameters or retrieving stored data.

The various settings, measured values and signals for function group IEC are describedin chapters 7 and 8.

3.4.5.2 Generic Object Oriented Substation Event (Function Group GOOSE)

For high-speed exchange of information between individual IEDs (intelligent electronicdevices) in a local network, the P63x provides function group GOOSE (IEC-GOOSE) asdefined in the IEC 61850 standard. GOOSE features high-speed and securetransmission for trip commands, blocking, enabling, contact position signals and othersignals.

"Goose Messages" are only transmitted by switches but not by routers. "GooseMessages" therefore remain in the local network to which the device is logged-on.

Activating and EnablingFunction group GOOSE can be activated by setting the parameter

GO OS E : F un c t i on g r ou p GOOS E . This parameter is only visible if the optionalEthernet communication module is fitted to the device. After activation of GOOSE, alldata points associated to this function group (setting parameters, binary state signalsetc.) become visible.The function can then be enabled or disabled by settingG O O S E : G e n e ra l e n a b l e U S E R .

The parameter settings for function groups IEC, GOOSE and GSSE in the device are notautomatically activated. Activation occurs either when the commandI E C : E n ab l e c o n f i gu r a t i on is executed or automatically when the device isswitched online with M A I N : D e v i c e o n - l i ne . In addition function group IEC mustbe configured and enabled.

Sending GOOSE

With GOOSE the P63x can transmit up to 32 logic binary state signals. Selection ofbinary state signals is made by settingGO OS E : Ou t p u t n f c t . a s s i g . (n = 1 to 32). The assignment of data objectindexes to logic state signals is made in the range from 1 to 32 according to theassignment to GOOSE outputs.

GOOSE is automatically sent with each new state change of a configured binary statesignal or an external device. There are numerous send repetitions in fixed ascendingtime periods (10 ms, 20 ms, 50 ms, 100 ms, 500 ms, 1000 ms, 2000 ms). If after2 seconds there is no further state change apparent, GOOSE is then sent cyclically at2-second intervals.

7/15/2019 Vol1 P632-635

66/605



In order to have unambiguous identification of GOOSE sent, characteristics such as theGoose ID number, MAC address, application ID and VLAN identifier must be enteredthrough parameter settings. Further characteristics are the 'Dataset ConfigurationRevision' with the fixed value "100" as well as the 'Dataset Reference', which is made upof the IED name (setting in function group IEC) and the fixed string"System/LLNO$GooseST".

With GOOSE up to 16 logic binary state signals can be received. Configuration of thelogic state signals received (GO OS E : I n p u t n f c t . as s i g . , where n = 1 to 16) ismade on the basis of the selection table of the binary inputs (opto coupler inputs).

For each state signal to be received from an external device the "Goose Message" mustbe selected that includes the information wanted by setting the Goose ID, the ApplicationID and the 'Dataset Reference'. With the further setting of the data object index and thedata attribute index through parameters, the required information from the chosenGOOSE will be selected. The device will not evaluate the identification features VLANidentifier and Dataset Configuration Revision that are also included in the GOOSEreceived.

Each GOOSE includes time information on the duration of validity of its information.

This corresponds to the double time period to the next GOOSE repetition. If the durationof validity has elapsed without having received this GOOSE again (i.e. because of acommunications fault), the received signals will automatically be set to their respectivedefault values GOO SE : Inp ut n def au l t or GOO SE : Ext .D ev . n def au l t(n = 1 to 16).

The various settings, measured values and signals for function group GOOSE aredescribed in chapters 7 and 8.

3.4.5.3 Generic Substation State Event (Function Group GSSE)

For high-speed exchange of information between individual IEDs (intelligent electronicdevices) in a local network, the P63x provides, as an additional functionality, the function

group GSSE (UCA2.0-GOOSE) as defined in the IEC 61850 standard. GSSE featureshigh-speed and secure transmission of logic binary state signals such as trip commands,blocking, enabling and other signals.

Activating and EnablingFunction Group GSSE can be activated by setting the parameter GS S E : F un c t i o ng r o up G SS E . This parameter is only visible if the optional Ethernet communicationmodule is fitted to the device. After activation of GSSE, all data points associated to thisfunction group (setting parameters, binary state signals etc.) become visible.The function can then be enabled or disabled by settingG S S E : G e n e ra l e n a b l e U S E R .

The parameter settings for function groups IEC, GOOSE and GSSE in the device are notautomatically activated. Activation occurs either when the command I E C : E n ab l ec o n f i gu r a t i on is executed or automatically when the device is switched online withMA I N : D ev i c e o n - l i ne . In addition the function group IEC must be configured andenabled.

7/15/2019 Vol1 P632-635

68/605



Sending GSSEWith GSSE up to 32 logic binary state signals can be sent. Selection of binary statesignals is made by settingGS S E : O u t pu t n f c t . a s s i g . (n = 1 to 32). Each state signal selected is to beassigned to a bit pair in GSSE (GS S E : O u t pu t n b i t pa i r (n = 1 to 32)), whichwill transmit this state signal.

GSSE is automatically sent with each state change of a selected state signal. There willbe multiple send repetitions at ascending time periods. The first send repetition occursat the given cycle time set with the parameter G S S E : M i n . c y c l e . The cycles forthe following send repetitions result from a conditional equation with the increment setwith the parameter GS S E : I n c r em en t . Should no further state changes occur up tothe time when the maximum cycle time has elapsed (GS S E : Ma x . c y c l e ) , thenGSSE will be sent cyclically at intervals as set for the max. cycle time.

In order to have unambiguous identification of a GSSE sent, the IED name is used whichwas set in function group IEC.

Receiving GSSEWith GSSE up to 32 logic binary state signals can be received. Configuration of the logicbinary state signals received (GS S E : I n pu t n f c t . as s i g . , where n = 1 to 32) ismade on the basis of the selection table of the binary inputs (opto coupler inputs).

For each state signal to be received, the GSSE message, which will include the requiredinformation, must be selected by setting the IED name (GS SE : I E D n am e) .Selection of information wanted from the selected GSSE will occur by setting the bit pair(GSSE: b i t pa i r ) .

Each GSSE includes time information on the duration of validity of its information.This corresponds to the double time period to the next GSSE repetition. If the durationof validity has elapsed without having received this GSSE again (i.e. because of acommunications fault), the signals received will automatically be set to their respectivedefault value ( GS S E : I n pu t n d ef au l t (n = 1 to 32)).

The various settings, measured values and signals for function group GSSE aredescribed in chapters 7 and 8.

3.5 IRIG-B Clock Synchronization (Funct ion Group IRIGB)

If, for example, a GPS receiver with IRIG-B connection is available, the internal clock ofthe P63x can be synchronized to run on GPS time using the optional IRIG-B interface.It should be noted that the IRIG-B signal holds information on the day only (day of thecurrent year). Using this information and the year set at the P63x, the P63x calculatesthe current date (DD.MM.YY).

Disabling or enabling theIRIG-B interface

The IRIG-B interface can be disabled or enabled via a setting parameter.

Synchronization readiness

If the IRIG-B interface is enabled and receiving a signal, the P63x checks the receivedsignal for plausibility. Implausible signals are rejected by the P63x. If the P63x does notreceive a correct signal in the long run, synchronization will not be ready any longer.

3.6 Configuration and Operating Mode of the Binary Inputs (Funct ion Group INP)

The P63x has opto coupler inputs for processing binary signals from the substation.The functions that will be activated in the P63x by triggering these binary signal inputsare defined by the configuration of the binary signal inputs. The typical response time is< 10 ms, although for reliability it is recommended that the initiating signal is maintainedfor at least 30 ms.

Configuring the binaryinputs

One function can be assigned to each binary signal input by configuration. The samefunction can be assigned to several signal inputs. Thus one function can be activatedfrom several control points having different signal voltages.

In this manual, we assume that the required functions (marked 'EXT' in the addressdescription) have been assigned to binary signal inputs by configuration.

It should be noted that time-critical applications such as time synchronization commandsshould not be mapped to the binary signal inputs of the analog I/O module as these havean increased reaction time due to internal processing.

Operating mode of thebinary inputs

The operating mode for each binary signal input can be defined. The user can specifywhether the presence (active 'high' mode) or the absence (active 'low' mode) of avoltage should be interpreted as the logic '1' signal. The display of the state of a binary

signal input 'low' or 'high' is independent of the setting for the operating mode of thesignal input.

3.7 Measured Data Input (Funct ion Group MEASI)

The P63x has a measured data input function involving two inputs. Direct current is fedto the P63x through one of the inputs. The other input is designed to connect aresistance thermometer.

The input current IDC is displayed as a measured operating value. The current that isconditioned for monitoring purposes (IDC,lin) is also displayed as a measured operatingvalue. In addition, it is monitored by the Limit Value Monitoring function to determinewhether it exceeds or falls below set thresholds (see "Limit Value Monitoring").

The measured temperature is also displayed as a measured operating value andmonitored by the limit value monitoring function to determine whether it exceeds or falls

below set thresholds (see "Limit Value Monitoring").

Disabling or enabling themeasured data inputfunction

The measured data input can be disabled or enabled via a setting parameter.

3.7.1 Direct Current Input

External measuring transducers normally supply an output current of 0 to 20 mA that isdirectly proportional to the physical quantity being measured the temperature, forexample.If the output current of the measuring transducer is directly proportional to the measuredquantity only in certain ranges, linearization can be arranged, provided that themeasured data input is set accordingly. Furthermore, for certain applications it may benecessary to limit the range being monitored or to monitor certain parts of the range witha higher or lower sensitivity. By setting the value pair MEASI: IDC x andME AS I: IDC, l in x, the user specifies which input current IDC will correspond to thecurrent that is monitored by the Limit Value Monitoring function, i.e., IDC,lin. The resultingpoints, called "interpolation points", are connected by straight lines in an IDC-IDC,lin

diagram. In order to implement a simple characteristic, it is sufficient to specify twointerpolation points, which are also used as limiting values (see figure 3-20). Up to20 interpolation points are available to implement a complex characteristic.When setting the characteristic the user must remember that only a monotonicallyincreasing curve is allowed (no peak or vee-shapes). If an invalid setting is entered, theSF MO N: In va li d s ca li ng ID C signal will be generated.
