Introduction


Introduction The configuration of the new tank inventory system consists of

modular parts:

• Entis Pro

• CIU Plus

• CIU Prime

• field instrumentation

Entis Pro This system displays calculated data from the CIU Plus. It is a

Windows7NT or Windows 2000 Professional based program,

displaying data in windows, boxes, tables, graphs, etc.

CIU Plus This unit calculates volume, standard volume, mass, density, flow

rate, etc. It requests data from the CIU Prime and calculates all other

data. It presents data to higher layered systems like Entis Pro,

SCADA, DCS, ENSITE, etc.

Host ports Up to four RS-232C/RS485 host ports can be installed to interface

host communication (Modbus) to Entis Pro, SCADA, DCS, ENSITE,

etc. For a description of the Modbus protocol, refer to the related

instruction manual.

Field ports Two fixed RS-232C/RS-485 field ports interface to a CIU Prime.

Automatic calculation After configuration, the CIU Plus automatically calculates data and

stores the information in a database. For a description of the

configuration and programming, refer to the instruction manual Ensite

Pro.

CIU Prime This unit is an interface between the field instrumentation and

inventory systems. It receives data from the field and converts it to

digital signals (Modbus) for systems like CIU Plus, PLC, ENSITE, etc.

Field instrumentation

The instruments in the field collect data like level, temperature, density

and/or pressure. The instruments are based on several principles:

mechanical, servo, radar, hydrostatic and capacitive or a combination.

The instruments measure the data and transmit it upon request of

higher layered systems.

Introduction


Safety


Safety

Safety aspects of the CIU Plus

The protection class for the CIU Plus housing is IP30 (NEMA 1), which

means that the CIU Plus can only be installed indoor in an explosion

safe area or in a protective cabinet.

Other environmental parameters are:

- ambient temperature: 0...60 °C

- relative humidity: 5...90 % (non condensing)

- over voltage category: II

- pollution degree: II

The host ports of the CIU Plus are galvanically separated. The field

ports of the CIU Plus do not have galvanic separation.

Personal safety The technician must have basic technical skills to be able to safely

operate the equipment and work in accordance with the (local)

requirements for electrical equipment.

Do not use the CIU Plus other than originally intended.

Modification to the CIU Plus may only be carried out by authorized

personnel.

Failure to adhere to this will invalidate the approval certificate.

Take all necessary personal protection measures and apply to the safety

regulations, valid for the working area.

Never start working before the work permit is signed by all parties.

Commissioning


Commissioning The CIU Plus is a user-configurable multi-processor unit and can be

totally programmed at site, or remotely, without opening the CIU Plus.

Commissioning is done in the following steps:

Check installation - Examine the mechanical installation

- Examine the electrical installation

Select tools - Use >Ensite= to collect the data from the field instruments

- Use >Ensite Pro= to configure the CIU Prime and Plus

- Use a spreadsheet program to generate strapping files

Prepare files - Ensite: make a log file of each field instrument

- Spreadsheet: make a strapping table for each tank.

(The filename shall be ><tankname>.TXT=, in which <tankname> is

the

name of the tank. The next page shows an example of what the file

should look like)

Program configuration - Ensite Pro: configure data inputs (use log files from Ensite)

- Ensite Pro: configure tanks (use strap files from spreadsheet)

- Ensite Pro: configure CIU Primes

- Ensite Pro: configure CIU Plus=s

- Ensite Pro: link data inputs, tanks, CIU Primes and CIU Plus=s

Download configuration - Ensite Pro: set communication parameters

- Ensite Pro: select physical communication path

- Ensite Pro: download all CIU Primes

- Ensite Pro: download all CIU Plus=s

Available tank entities The CIU Plus is delivered with a pre-programmed Tank Record lay-out

(list of tank entities) for communication with Entis Pro. The lay-out for

communication with Entis Pro is fixed, however it is possible to alter

the lay-out to fit other requirements.

A selection can be made which data must be presented in the user

defined tank data area. This because of the lot of information which

can be retrieved.

One tank data reply packet is selected which is used for all tanks

available to the modbus host.

The sequence how the tanks are organized in the user defined

modbus map is programmable.

Read tank data


There are two methods possible to organize the user defined modbus

memory map:

1. Tank oriented.

Data in the modbus memory map is grouped per tank.

Start address of memory map is programmable. Default start address

is 0000.

The start address-interval between the tank records is programmable.

2. Data oriented.

Statuses


Statuses Each measured and each calculated entity in the CIU Plus contains a

16 bits status register.

High byte The high byte, the validity byte, is used to indicate if the data of this

entity is available (valid) and, if not valid, to indicate why the data is

not available (invalid).

Low byte The low byte is used to indicate the status of the data.

Validity byte The data validity byte is a hexadecimal number.

If the validity byte is >=80HEX

, the related data is invalid. If the data of

an entity is invalid, all derived data shows the same code in its data

validity byte and the status indicates how the data field should be

displayed (>FFFF=, blanks, etc.).

If the validity byte is <80HEX

, the related data is valid. Then additional

information is given.

Some examples are listed below. If the complete list is required

contact Enraf BV.

Suggested characters to display depending on the contents of the status

byte:

- uncalibrated = >#=

- manual = >&=

- stored = >S=

- reduced accuracy = >?=

The data status basically exists of two parts which should be displayed

in tabular data in two separate columns:

- bit 7, which indicates whether the data is calibrated or not

- bit 6...0, which (in decreasing priority) tell something about the physical

status of the data.

Validity >= 80HEX

represents invalid data.

Suggested characters to display: >FFFF= or >blanks=

Modbus number representation


Modbus number representation The CIU Plus will be delivered with a pre-programmed Tank Record

lay-out for communication with Entis Pro. The lay-out for

communication with Entis Pro is fixed. However in case of

communication to another system the customer is able to alter the lay-

out to fit his own requirements.

This chapter describes the way data can be represented in the

modbus registers:

ID53,60,61,62,63 and 64 are available in CIU Plus firmware version

1.003 and higher.

In CIU Plus firmware versions up to 1.002 ID50 was available. ID50 is

identical to ID64 in CIU Plus firmware versions 1.003 and higher.



Scaling and offset Scaling and offset are defined as follows:

• The value of the data that will be available for the user is

calculated as follows:

Register value = (data * scaling) + offset

• Per selected data entity a scaling and offset value can be

entered. These entered values are used for calculating the

register value.

• The original data measured or calculated by the CIU Plus is

available in the dimension and resolution as defined by the

dimension table.

• This data is represented in the requested representation in the

output registers.



Example 1: Level : 22316.2 mm

Dimension : mm

Scaling : 0.01

Offset : 0

Data type : unsigned double register (ID=63)

Calculation : (22316.2 * 0.01) + 0 = 223.162

Data in reg. 1 : 223DEC


Example 2: Temperature : -8.23 °C

Dimension : °C

Scaling : 10

Offset : 100

Data type : 16 bit unsigned integer (ID=40)

Calculation : (-8.23 * 10) + 100 = 17.7

Data in reg. : 18 (rounded)

Example 3: Volume : 87654.321 m3

Dimension : m3

Scaling : 0.1

Offset : 0

Data type : unsigned double register (ID=64)

Calculation: : (87654.321 * 0.1) + 0 = 8765.4321



Example 4: Mass : 87654321 kg

Dimension : kg

Scaling : 1

Offset : 0

Data type : 32 bit signed integer (ID=52)

Calculation : (87654321 * 1) + 0 = 87654321

Data in reg. : 05 39 7F B1HEX

Maintenance / trouble shooting


Maintenance / trouble shooting

Maintenance The CIU Plus requires neither preventive nor periodical maintenance.

Trouble shooting If something appears to be wrong, proceed as follows:

1. Check mains voltage; OK: yes -> step 2

no -> check/replace

fuses

2. Check cabling: not connected -> connect

connected -> step 3

3. Check communication: yes -> finish

no -> step 4

4. Start >Ensite Pro=

5. Go to >Diagnostic data=

6. Press the >Update=-button to have the current values.

7. Press the >Print...=-button to print the data.

8. Contact Honeywell Enraf with diagnostic data.

Cleaning of the housing of the CIU Plus should be done with a moist

cloth only.

After switching on the CIU Plus it will take approximately 1 minute before

it will be able to communicate via the host ports.

The ´Alive´ LED (green LED under the red power LED) gives an

indication if the CIU Plus is in healthy condition.

In case healthy the LED is on for 2 seconds and off for 1 second etc.

Note that the healthy flash rhythm is different from the flash rhythm of

the Alive LED on the CIU Prime.
