This article describes the Modbus-TCP communication between Omron Sysmac PLC NJ and the Omron CelciuX Ethernet gateway module.
The CelciuX Ethernet-TCP gateway (EJ1N-HFU-ETN) can be used either with CelciuX temperature units or as a gateway for Modbus-RTU devices or even for both.
Up to 247 pcs. of MX2 inverters can be controlled using CelciuX EJ1N-HFU-ETN as gateway (not realtime).
