7 3. Description MODBUS is a master-slave communication protocol, able to support up to 247 slaves arranged in a bus or star network. The data physical link layer can be RS232 for a point-to-point connection or RS485 for a network. Semi-duplex communication is used. Network messages can be of the Query-Response or Broadcast type. The Query-Response command is transmitted by the Master to a single Slave and is generally followed by an answering message. The Broadcast command is transmitted by the Master to all Slaves and it is never followed by an answer. MODBUS uses two transmission modes. 1. ASCII mode: a limited set of characters is used for communication. 2. RTU mode: binary, with time-frame synchronisation, faster than the ASCII Mode; the data block is fifty per cent shorter than the ASCII mode block. During the configuration stage the user must define the transmission mode for all the devices connected with the network. The two abovementioned modes cannot be simultaneously implemented. NOTE The following protocol description refers to the RS485 communication. The Modbus protocol cannot be used on infra red port. STRUCTURE OF A GENERIC MESSAGE: FRAME ADDRESS FUNCTION DATA ERROR FRAME START FIELD CODE FIELD CHECK END FRAME START = Message start marker. ADDRESS FIELD = Device address for Query- Response communication mode. For a Broadcast-type message the address field is 00. FUNCTION CODE = Operation code to be performed. 3-1 Description

8 DATA FIELD = Includes the data field. ERROR CHECK = Error correction code field. FRAME END = End message marker. COMMUNICATION FRAME STRUCTURE ASCII mode: Bit per byte = mode a) 1 Start, 7 Bit, 1 Parity, 1 Stop mode b) 1 Start, 7 Bit, 2 Stop FRAME START = character : (0x3A) ADDRESS FIELD = 2 characters FUNCTION CODE = 2 characters DATA FIELD = 2 x N characters ERROR CHECK = LRC (BCC) 8 bit FRAME END = characters CR LF (0x0D 0x0A) RTU mode: Bit per byte = mode a) 1 Start, 8 Bit, 1 Parity, 1 Stop mode b) 1 Start, 8 Bit, 2 Stop FRAME START = silence on line for time >= 4 characters ADDRESS FIELD = 1 character FUNCTION CODE = 1 character DATA FIELD = N characters ERROR CHECK = CRC 16 bit FRAME END = silence on line for time >= 4 characters. 3-2 Description

11 4. Read Registers (Function code $03) Read the binary contents of holding registers (4X references) in the slave. Broadcast is not supported. The query message specifies the starting register and the quantity of registers to read. NOTE It is possible to read more than one variable at the same time only if their addresses are consecutive. Variables cannot be reading with two separate commands; a single command is needed. QUERY: FRAME ADDRESS FUNCTION START NO. OF ERROR FRAME START FIELD CODE ADDRESS REGISTERS CHECK END FRAME START = Message start marker. ADDRESS FIELD = device address (00...F7 HEX) (1 byte). FUNCTION CODE = Operation code (03 HEX) (1 byte). START ADDRESS = First register address to read (2 bytes). NO. OF REGISTERS = Number of registers (max 126) to read (4 bytes or 2 bytes for 1 IEEE). ERROR CHECK = Control character (check sum) FRAME END = End message marker. The data in the response message is arranged as two bytes per register, with the binary contents right-hand justified within each byte. For each register, the first byte contains the high order bits and the second contains the low order bits. 4-1 Read Registers

12 RESPONSE: FRAME ADDRESS FUNCTION NO. OF D0 D1.. Dn ERROR FRAME START FIELD CODE BYTES CHECK END FRAME START = Message start marker. ADDRESS FIELD = device address (00...F7 HEX) (1 byte). FUNCTION CODE = Operation code (03 HEX) (1 byte). NO. OF SENT BYTES = Number of data bytes (00...?? CRC 1 bit 1 register requires 2 data bytes. D0, D1,.., Dn = Data byte (00...?? HEX) (Register number x 2 = no. of bytes). ERROR CHECK = Control character (check sum) FRAME END = End message marker. See Section 7 for the and Section 8 for Examples. 4.1 Floating point as per IEEE Standard The basic format allows a IEEE standard floating-point number to be represented in a single-32 bit format, as shown below: N.n = (-1) S 2 e -127 (1.f ) where S is the sign bit, e is the first part of the exponent and f is the decimal fraction placed next to 1. Internally the exponent is 8 bits in length and the stored fraction is 23 bits long. The floating-point format is shown as follows: ======================================= S e f ======================================= < bit number 4-2 Read Registers

See Section 7 for the. Example of conversion of value shown with floating point Value read with floating point: 45AACC00( 16 ) Value converted in binary format: ( 2 ) sign = 0 exponent = ( 2 ) = 139( 10 ) fraction = ( 2 ) = ( 10 ) N.n = (-1) S 2 e -127 (1.f ) = = (-1) ( ) = = (+1) (4096) ( ) = = Read Registers

14 5. Parameters set-up (Function Code $10) Pre-sets values into a sequence of holding registers (4X references). In Broadcast mode, the function pre-sets the same register references in all connected slaves. NOTE:The function will override the controller s memory protection state. The pre-set values will remain valid in the registers until the controller s logic next solves the register contents. The register values will remain the same if they are not programmed in the controller s logic. The query message specifies the register reference to be pre-set. Registers are addressed starting from zero: register 1 is addressed as 0. NOTE It is possible to write multiple variable at the same time if only their addresses are consecutive. Variables cannot be written with separate commands; a single command is needed. QUERY: FRAME ADDRESS FUNCTION START NO. OF NO.OF D0 D1.. Dn ERROR FRAME START FIELD.

15 NO. OF BYTES = Number of data bytes (01/02 HEX) (1 byte). 1 register requires 2 data bytes. D0, D1,.., Dn = Data bytes (00...?? HEX) (1 byte) (No. of register x 2 = no. of bytes). ERROR CHECK = Control character (check sum). FRAME END = End message marker. The normal response returns the following pre-set parameters: slave address, function code, starting address and the quantity of register. RESPONSE: FRAME ADDRESS FUNCTION START NO. OF ERROR FRAME START FIELD CODE ADDRESS REGISTERS CHECK END FRAME START = Message start marker. ADDRESS FIELD = Device address (00...F7 HEX) (1 byte).
