I've been using Mitsubishi PLCs for about 15 years in control panels for stand alone packaging machinery. The little FX1S does all I need with it's variety of BD boards. My only complaint is the lack of a port for program monitoring when an HMI and BD board are both connected to the PLC.
I'm looking at the 485BD board to communicate to one or more VFDs. Specifically the KBVF with it's add-on communication board. The KBVF uses a Modbus protocol that doesn't look to be compatible with the 485BD.
The Modbus data packet doesn't use an ENQ/ACK/NACK. Any recommendations on how to communicate with the drive using the 485BD board?
