Connect Modbus slaves to ETHERNET

The EJ1N-HFU-ETN provides the solution to connect a CelciuX° (EJ1) in-panel multi-loop PID controller to PROFINET and Modbus/TCP. Although built on the CelciuX° (EJ1) platform, this unit can be used as a gateway for discrete Modbus units when only using the EJ1N-EDU endplate.

  • Connects Modbus serial slaves to PROFINET and Modbus/TCP.
  • Built for integration into the CelciuX° (EJ1).
  • Usable as a gateway for discrete units like E5_N-series temperature controllers and MX2 inverters.
  • Flexible implementation with standard .gsd file.
  • Ethernet/IP gateway just for EJ1N-TC2 cards: up to 24 EJ1N-TC2 connectable (48 loops in total).
