E06 FIELDBUS REGISTER TABLE FORMAT RULES

This document lists all of the available registers for the control unit with the abovementioned software. The registers are described using a fixed format. Below is a detailed explanation of the various elements that describe any given register.

Register Name:

This is the name of the register, of which there are four basic types. The first three letters of the register name define the register type and or operation that can be performed. The rest of the name simply describes which particular bit of data is involved.

Type Register type description “Adv” A register which is part of a “broadcast” message type. This data is transmitted on the Airbus485 network without the need for outside influence. The data is sent at a particular interval and/or when the status of Airbus485 compatible system hardware changes. There is no possibility to request ?broadcast? message types. Although there is no ability to independently request the ?broadcast? message data type on an Airbus485 network, the gateway providing fieldbus access captures and stores the ?broadcast? data, thereby allowing the fieldbus master to request (read) the data elements whenever required. Remark !!: Obtaining data from “Adv” type registers is an efficient way of obtaining data and causes the minimum of communication overhead on the Airbus485 network. As a result, using “Adv” type registers will also improve overall system performance, including the speed at which the fieldbus master can operate. “Cmd” “Cmd”: a register address used to trigger sending a command message to the unit. Writing the appropriate data value will cause the equivalent command to be sent. “Get” A register address that can be used to read data. Modern type controllers (R1,S1,T1,...) support reading elements of the overall data block within the range 4000...5FFF (minimum size is 1 word: 16 bits of data). “Set” A register address that can be used to write data. For a write operation to be accepted it is always necessary to write a full size data block starting at the specified register address Available Function:

This defines the type of operation that can be performed. The possible operation types are: “Read data” and “Write data”.

Available Register Range: (always in hexadecimal notation)

This defines the range of the data block the register is part of. It shows the start address of the data block (first register: XXXX) and the end of the data block (last register:YYYY) in the format: XXXX...YYYY. Note: in case the registers are part of a”broadcast” (Adv) data block or are part of the range 4000....5FFF it is always possible to request individual (minimum 1 word) or partial sections of the data block. Max Register Length: (always in hexadecimal notation)

This defines the maximum data size (number of register) in the overall data block.

Register Address (always in hexadecimal notation)

This defines the actual register address to access the register. In case the FIELDBUS being used is MODBUS RTU the register addresses are exactly the same as \holding register addresses\adresses are simply numerical identifiers for the various data items.

Register Length: (always in hexadecimal notation)

This defines the fundamental size of the data at the actual register address. It is shown as number of registers (16 bit words) and/or the number of bytes.

Just below the “Register Length” entry there is either a description of the “DATA-TYPE”, “DATA-CONVERSION” or additional comments to describe the structure of the data in more detail.

Descriptions of the various “DATA-TYPE” and “DATA-CONVERSION” items can be found at the bottom of this document.

General terms used in this document

MSB: Most Significant Byte (always the “high order” byte in a 16 bit word => also the “first” byte)

LSB: Least Significant Byte (always the “low order” byte in a 16 bit word => also the “second” byte)

FIELDBUS REGISTER TABLE DATA ACCESS RULES

In principle accessing the data within a data block is only possible when using the full data block size.

Example: the “GetStatus” request for a compressor always produces 3 data words. When requesting the data it is necessary to always request the data as 3 word data block, otherwise the data cannot be read.

The only exceptions to the rule are “broadcast” (Adv) data blocks (all controller models) and register addresses within the range 4000...5FFF. For those data blocks it is possible to read individual data elements within the data block. Any request for data that falls within the specified data block range is acceptable. Write operations are only possible using the full data block size !!!

Example: a basic sequencer unit broadcast data block which contains 7 individual registers: - Register F020: AdvAvailableStatus - Register F021: AdvRunningStatus - Register F022: AdvLoadedStatus - Register F023: AdvAlarmStatus - Register F024: AdvSystemStatus - Register F025: AdvTargetPressure - Register F026: AdvSystemPressure

To access data within this data block it is possible to:

- Request each individual register (always 1 word). - Ask for two subsequent registers (e.g: F021 & F022) - Ask for any set of registers within the block.

- Ask for the entire data block (F020...F026) with a single request.

The only basic rule is that the data should be requested in such a way that the combination of register start address + number of registers does not exceed the last register address, e.g.: the gateway will not accept a request starting at address F025 with a length of 3 registers.
