C.1 MEMOBUS/Modbus Configuration

C.1 MEMOBUS/Modbus Configuration

Regenerative unit can be controlled from a PLC or other master device via serial communications using the MEMOBUS/
Modbus protocol.

MEMOBUS/Modbus communications can be configured using one master (PLC) and up to 255 slaves. The regenerative
unit

has slave functionality only, and serial communication is normally initiated from the master and responded to by the
slaves.

The master communicates with the specified slave regenerative unit. The address or node for each slave must be set prior
so the master can communicate with the slave at that address. A slave that receives a command from the master will
perform the specified function and send a response back to the master.
