1. IntroductionAMI Transmitters can be operated as intelligent slave devices on the Modbus/JBUS using twisted pair RS485 lines.

Modbus/Jbus The Modbus/Jbus Protocol communicates using a master-slave technique, in which only one device (the master) can initiate transactions (queries). The other devices (the slaves) respond by supplying the requested data to the master, or by taking the action requested in the query. Typical master devices include host processors, PLCs etc. Typical slaves can be PLCs or intelligent transmitters/controllers like the AMI transmitters.In some cases several instruments use the same set of data and are therefore covered in the same chapter. The instruments concerned and the corresponding chapters are listed in the fol-lowing table.

ModbusIntroduction

1.1. The Query-Response CycleThe query The function code in the query tells the addressed slave device what kind of action to perform.

The data bytes contain any additional information the slave will need to function. For example, function code 03 will query the slave to read holding registers and respond with their contents. The data field must contain the information telling the slave which register to start at and how many registers to read.

The response If the slave makes a normal response, the function code in the response is an echo of the function code in the query.The data bytes contain the data collected by the slave.

Serialtransmission

modes

Modbus supports two transmission modes: ASCII or RTU.The AMI Instruments support Modbus RTU (Remote Terminal Unit) mode only.

RTU mode In RTU mode, each 8-bit byte in a message contains two 4-bit hexadecimal characters. The main advantage of this mode is that its greater character density allows better data throughput than ASCII for the same baud rate. Each message must be transmitted in a continuous stream. Users select the desired serial port communication parameters (baud rate, parity mode, etc). The serial parameters must be the same for all devices on a Modbus network.

Codingsystem

Eight bit binary 1 start bit 8 data bits, least significant bit sent first 1 bit for even / odd parity, no bit for no parity 1 stop bit if parity is used, 2 bits if no parity Cyclic Redundancy Check (CRC) RTU framing: messages start with a silent interval of at least 3 ½ character times. A simi-

lar interval of at least 3 ½ character times marks the end of the message.

1.2. Data and Control FunctionsData address in

Modbus messagesAll data addresses in Modbus Messages are referenced to zero. The first occurrence of a data item is addressed as item number zero. For example:

Holding Register 40001 is addressed as register 0000 in the data address field of the message. The function code field already specifies a holding register operation. Therefore the 4x reference is implicit.

Modbus functioncodes

The list below shows the function codes supported by the AMI Instruments. Codes are listed in decimal. Function codes not supported return an exception response 02 to the master.

Data re-presentation

The process and parameter data of the AMI Instruments are represented by float (IEEE 754), signed or unsigned integer values. Depending on the range of the value, float, integer8, unsigned8, integer16, unsigned16, integer32 or unsigned32 representation is used.

Discreteinputs

Alarm &Status bits are packed as one input per bit of the data field.

Definition:big-endian and

little-endian

Big-endian and little-endian are terms that describe the order in which a sequence of bytes are stored in computer memory. Big-endian is an order in which the "big end" (most significant value in the sequence) is stored first (at the lowest storage address). Little-endian is an order in which the "little end" (least significant value in the sequence) is stored first. For example, in a big-endian computer, the two bytes required for the hexadecimal number 4F52 would be stored as 4F52 in storage. In a little-endian system, it would be stored as 524F.

ATTENTION

Big-endian format is used.
