The ET 200SP multifieldbus interface module IM155-6MF HF with firmware version V5.0.3 can communicate to different controllers via three fieldbus protocols: Profinet, EtherNet/IP and Modbus TCP. It can be used by customers who, because of end user preference, occasionally use other Ethernet-based I/O systems in addition to Profinet; in applications for energy data acquisition via Modbus TCP, for example, via AI energy meter modules; and in customer segments that until now have used Modbus TCP or EtherNet/IP controllers exclusively. This firmware version can be used with MFCT Version V1.0.0.2 or higher. It is recommended to update the firmware of older interface modules to firmware version V5.0.3.
