Function Code 06H - GE MOTOR MANAGER 2 Instruction Manual

6 COMMUNICATIONS
Modbus Implementation: Preset Single Register
MM2 Implementation: Store Single Setpoint
This command allows the master to store a single setpoint into the memory of a MM2. The slave
response to this function code is to echo the entire master transmission.
For example, request slave 17 to store the value 01F4 in setpoint address 1020. After the transmis-
sion in this example is complete, setpoints address 1020 will contain the value 01F4. The master/
slave packet format is shown below:
