The modules with HART (Highway Addressable Remote Transducer) which can be used in ET 200M remote I/O stations (with IM 153‑2 High Feature interface module) permit connection of HART devices to the SIMATIC PCS 7 automation system.

Transmitters and HART actuators that are certified for digital communication with the HART protocol can be connected through these modules.

With 0/4 to 20 mA technology, conventional transmitters/actuators without HART protocol can also be connected.

All modules with HART come with diagnostics capability (channel and module diagnostics). The diagnostics and monitoring functions are directly available in SIMATIC PCS 7. They require no additional engineering. Plain text messages output on the operator station provide information on faults or changes in the HART parameter settings.

Homogenous integration in the SIMATIC Process Device Manager (PDM) and the PCS 7 Asset Management permit intuitive online diagnostics and parameterization of all connected field devices from a central position.
