3.2 Setting the Serial Transmission Parameters – Fig. 3.1 Fig. 3.1 shows the display readouts and options available when defining the serial transmission rate and bit parity for COMMANDER 100, 150, 160 and V100 instruments. Further detail on the procedure required to set each parameter are shown in Section 4.3.4 of the relevant User Guide. -
Page 9: Modbus Protocol
4 MODBUS PROTOCOL Information. • The COMMANDER 100, 150, 160 and V100 operate as MODBUS, Remote Terminal Unit (RTU) slaves. • Parity checking – detects transmission errors in individual characters. • Cyclic redundancy checking – detects errors in the master messages and slave responses. -
Page 10: Modbus Function Codes
…4 MODBUS PROTOCOL 4.2 MODBUS Function Codes The function code instructs the addressed slave which function to perform. Table 4.1 shows the function codes, and describes the action they initiate. Function Function Description Code Title Read Read up to 16 consecutive discrete (Boolean) points Coil Status from a specific starting point. -
Page 11: Modbus Functions
5 MODBUS FUNCTIONS This section shows typical examples of MODBUS function codes 01, 03, 05, 06, 08 and 16. Not all addressable parameters used in the examples which follow are valid for all instrument types – see Sections 7.1 to 7.4. 5.1 Read Coil Status –... -

…5 MODBUS FUNCTIONS 5.2 Read Holding Register – Function Code 03 5.2.1 Read Holding Register Query The Read Holding Register Query obtains the contents of up to eight holding registers in the addressed slave. Note. The data start register must contain the offset address of the first register to be accessed, e.g. -

5 MODBUS FUNCTIONS… 5.3 Force Single Coil – Function Code 05 5.3.1 Force Single Coil Query This message forces a single coil either ON or OFF. The data value 65,280 (FF00 HEX) sets the coil ON and the value zero turns it OFF. All other values are illegal and have no effect on coil status. -
Page 14: Preset Single Register - Function Code 06
…5 MODBUS FUNCTIONS Preset Single Register – Function Code 06 5.4.1 Preset Single Register Query The Preset Single Register Query modifies the contents of a holding register. Note. Function codes 05, 06 and 16 are the only messages that are recognized as valid for broadcast. -
Page 15: Loopback Test - Function Code 08
5 MODBUS FUNCTIONS… Loopback Test – Function Code 08 5.5.1 Loopback Test Query The Loopback Test Query tests the MODBUS system and does not affect the operation of the slave. Variations in the response may indicate faults in the MODBUS system. The information field contains two bytes for the designation of the diagnostic code followed by two bytes to designate the action to be taken. -
Page 16: Write Multiple Registers - Function Code 16
…5 MODBUS FUNCTIONS Write Multiple Registers – Function Code 16 5.6.1 Write Multiple Registers Query This message is used to change the contents of up to eight holding registers at a time. When used with slave address zero (broadcast mode) all slave controllers load the selected registers with the contents specified. -
