Function Code 06H

Modbus Implementation: Preset Single Register

MM300 Implementation: Store Single Setpoint

This command allows the master to store a single setpoint into the memory of a MM300 The slave response to this function code is to echo the entire master transmission.

For example, request slave 17 to store the value 2 in setpoint address 04 5C. After the transmission in this example is complete, setpoints address 04 5C will contain the value

01F4. The master/slave packet format is shown below:
