Function Code 05H - GE MOTOR MANAGER 2 Instruction Manual

6.2 MODBUS FUNCTIONS
Modbus Implementation: Force Single Coil
MM2 Implementation: Execute Operation
This function code allows the master to request a MM2 to perform specific command operations. The
commands supported by the MM2 are listed in Section 6.4: APPLICATIONS on page 6–14.
For example, to request slave 17 to execute operation code 1 (reset), we have the following master/
slave packet format:
