Benefits

• Service-proven analog measured value transmission


• Simultaneous digital communication with bidirectional data transmission


• Possibility of transmitting several measured variables from one field device (e.g. diagnosis, maintenance and process data)


• Connection to higher-level systems such as PROFIBUS DP


• Easy installation and startup

Use in conjunction with SIMATIC PDM

• Cross-vendor operation of all HART devices by means of standardized parameter records


• HART field devices that are described by HART DD are integrated in SIMATIC PDM through the HCF catalog. HART DD (Device Description) is standardized in SIMATIC PDM, multi-vendor and very widely used. Other HART field devices are integrated in SIMATIC PDM through EDD (Electronic Device Description)


• Easy operation and startup of field devices, also in hard-to-reach locations


• Expanded diagnosis, evaluation and logging functions

Application

These devices can be connected in different ways:

• Using the distributed I/O system
  
  – SIMATIC ET 200M with the HART modules
  
  – SIMATIC ET 200iSP with the HART modules
  
  or with analog modules 4 to 20 mA and a HART handheld communicator


• Using a HART modem, with which a point-to-point connection is established between the PC or engineering station and the HART device


• Using HART multiplexers, which are contained in the HART server of the HCF
