Serial Communication


Serial communication allows the FX Series to connect both efficiently and reliably with other PLCs, sensors, printers, and modems, etc. Multi-drop networks, non-protocol communication, and remote maintenance are just some of the many uses.

Both an open network and a serial communicator, Modbus-RTU allows the FX3U and FX3UC PLCs to interface with a wide range of equipment and devices. Using RS-485 and RS-232C the FX3U-485ADP-MB and FX3U-232ADP-MB expand the networking capabilities of the FX system while still supporting general communication with other FX systems, non-protocol devices, and serial modems.
