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.

Safety

Safety Safety aspects of the CIU Plus Do not use the CIU Plus other than originally intended.

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. Modification to the CIU Plus may only be carried out by authorized personnel. Failure to adhere to this will invalidate the approval certificate.

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. 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.

Statuses

Statuses High byte

Low byte

Each measured and each calculated entity in the CIU Plus contains a 16 bits status register. 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). 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 Description (bit set) Generate Alarm No Data Available Killed Over Range Under Range Un-initialised

Stored Reduced Accuracy

Validity < 80HEX represents valid data. 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 layout to fit his own requirements.

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.

Maintenance / trouble shooting

Maintenance / trouble shooting Maintenance

The CIU Plus requires neither preventive nor periodical maintenance. Cleaning of the housing of the CIU Plus should be done with a moist cloth only.

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. 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.
