EXECUTE OPERATION Modbus Implementation: Force Single Coil 469 Implementation: Execute Operation This function code allows the master to request an 469 to perform specific command operations. The command numbers listed in the Commands area of the memory map correspond to operation code for function code 05. The operation commands can also be initiated by writing to the Commands area of the memory map using function code 16. Refer to Section 6.2.8: Function Code 16: Store Multiple Setpoints on page 6–8 for complete details. Supported Operations: Reset 469 (operation code 1); Motor Start (operation code 2) Motor Stop (operation code 3); Waveform Trigger (operation code 4) MESSAGE FORMAT AND EXAMPLE: Reset 469 (operation code 1). 6.2.5 FUNCTION CODE 06: STORE SINGLE SETPOINT Modbus Implementation: Preset Single Register 469 Implementation: Store Single Setpoint This command allows the master to store a single setpoint into the memory of an 469. The slave response to this function code is to echo the entire master transmission. MESSAGE FORMAT AND EXAMPLE: Request slave 11 to store the value 01F4 in Setpoint address 1180. After the transmission in this example is complete, setpoints address 1180 will contain the value 01F4.

A short message length allows for rapid reading of status. The status byte returned will have individual bits set to 1 or 0 depending on the status of the slave device. 469 General Status Byte: If status is neither stopped or running, the motor is starting. MESSAGE FORMAT AND EXAMPLE: Request status from slave 11. 6.2.7 FUNCTION CODE 08: LOOPBACK TEST Modbus Implementation: Loopback Test 469 Implementation: Loopback Test This function is used to test the integrity of the communication link. The 469 will echo the request. MESSAGE FORMAT AND EXAMPLE: Loopback test from slave 11.

Modbus "registers" are 16-bit (two byte) values transmitted high order byte first. Thus all 469 setpoints are sent as two byte values. The maximum number of setpoints that can be stored in one transmission is dependent on the slave device. Modbus allows up to a maximum of 60 holding registers to be stored. The 469 response to this function code is to echo the slave address, function code, starting address, the number of Setpoints stored, and the CRC. MESSAGE FORMAT AND EXAMPLE: Request slave 11 to store the value 01F4 to Setpoint address 1180 and the value 01DE to setpoint address 1181.
