Omron V1000 User Manual

C.2 MEMOBUS/Modbus Configuration
Drives can be controlled from a PLC or other master device via serial communications using the MEMOBUS/Modbus
protocol.
MEMOBUS/Modbus communication can be configured using one master (PLC) and a maximum of 255 slaves. The drive
has slave functionality only, meaning that serial communication is normally initiated from the master and responded to
by the slaves.
The master performs serial communications with only one slave at a time. The address or node for each slave must be set
beforehand so that 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 then send a response back to the master.
