5 Introduction Introduction The configuration of the new tank inventory system consists of modular parts: Entis Pro CIU Plus CIU Prime field instrumentation Entis Pro CIU Plus Host ports Field ports Automatic calculation CIU Prime This system displays calculated data from the CIU Plus. It is a Windows 7 NT or Windows 2000 Professional based program, displaying data in windows, boxes, tables, graphs, etc. 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. 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. Two fixed RS-232C/RS-485 field ports interface to a CIU Prime. 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. 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. Instruction manual 880 CIU Plus Page 5

7 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: C - relative humidity: % (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.

23 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 >=80 HEX, 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 <80 HEX, the related data is valid. Then additional information is given. Some examples are listed below. If the complete list is required contact Enraf BV. Validity byte Description 0x00 Valid data - 0x6F 0x70 Reduced accuracy in ambient temperature Stored because of water dip Action x81 No data available For derived data it is necessary to check all input parameters for this code 0x82 Killed data For derived data it is necessary to check all input parameters for this code 0xA4 General conversion error Check input and output value dimensions Instruction manual 880 CIU Plus Page 23

24 Statuses Status byte The data status byte is bit coded. The meaning of the bits depends on the validity byte (<80 HEX or >=80 HEX ) Status Bit Validity < 80 HEX Description (bit set) Validity >= 80 HEX Description (bit set) 7 Uncalibrated Generate Alarm 6 Manual No Data Available 5 Killed 4 Over Range 3 Under Range 2 Un-initialised 1 Stored 0 Reduced Accuracy Validity < 80 HEX 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 >= 80 HEX represents invalid data. Suggested characters to display: >FFFF= or >blanks= Page 24 Instruction manual 880 CIU Plus

25 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. This chapter describes the way data can be represented in the modbus registers: ID Data type 0 Not a number (just data) Nr. of registers used Description Data is represented according the item definition (status, index, bit coded, etc.) 15 ASCII string Data represents a string of two ASCII characters per register. Empty registers contain >0'. 25 Unicode characters bit unsigned integer bit signed integer bit decimal float Data represents a string of one Unicode character per register. Empty registers contain >0'. 1 Data is transmitted as contents of the register. Value FFFF HEX (65535 DEC ) is seen as failure 1 Represented in 2's complement. bit 15: sign bit : data e.g HEX = 0 e.g HEX = 1 e.g. 7FFF HEX = failure e.g HEX = e.g. FFFF HEX = -1 1 Mostly used for scaling and offset. bit 15: sign, 0 = pos., 1 = neg. bit : exponent power of 10 bit : mantissa e.g HEX = 0 e.g HEX = e.g HEX = 100 e.g. 5A16 HEX = Instruction manual 880 CIU Plus Page 25

26 Modbus number representation ID Data type Nr. of registers used Description e.g. 73E8 HEX = 1Α10 10 e.g. 7BFF HEX = failure e.g HEX = bit signed 1 bit : if not 000 see further: bit 12: sign, 0 = pos., 1 = neg. bit : analogue value e.g. EF FF HEX = invalid bit signed integer bit floating point bit floating point (swapped) 2 Binary data, covering data range between and e.g HEX = 0 e.g HEX = 1 e.g. 7F FF FF FF HEX = invalid e.g. FF FF FF FF HEX = -1 2 Data in two registers.

In CIU Plus firmware versions up to ID50 was available. ID50 is identical to ID64 in CIU Plus firmware versions and higher. Instruction manual 880 CIU Plus Page 27

28 Modbus number representation 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. Page 28 Instruction manual 880 CIU Plus

29 Modbus number representation Example 1: Level : mm Dimension : mm Scaling : 0.01 Offset : 0 Data type : unsigned double register (ID=63) Calculation : ( * 0.01) + 0 = Data in reg. 1 : 223 DEC Data in reg. 2 : 162 DEC Example 2: Temperature : C Dimension : C Scaling : 10 Offset : 100 Data type : 16 bit unsigned integer (ID=40) Calculation : (-8.23 * 10) = 17.7 Data in reg. : 18 (rounded) Example 3: Volume : m3 Dimension : m3 Scaling : 0.1 Offset : 0 Data type : unsigned double register (ID=64) Calculation: : ( * 0.1) + 0 = Data in reg. 1 : 8765 DEC Data in reg. 2 : 4321 DEC Example 4: Mass : kg Dimension : kg Scaling : 1 Offset : 0 Data type : 32 bit signed integer (ID=52) Calculation : ( * 1) + 0 = Data in reg. : F B1 HEX Instruction manual 880 CIU Plus Page 29

30 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.
