YASKAWA A1000 HHP User Manual

B.1 MEMOBUS/Modbus Configuration
Drives 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 31 slaves. The drive has slave
functionality only, and 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.
