Information from field devices such as pressure and temperature transmitters and from level and flow meters is of great significance in process automation. In this respect, there is often a demand for supplying these directly with power and also using them in hazardous areas
This demand is met by FOUNDATION Fieldbus. The Compact FF Link (CFFL) is available on the PROFIBUS DP for integration into SIMATIC PCS 7.
Compared to conventional 4-20 mA technology, the fieldbus technology offers fundamental advantages, e.g. with regard to simple and cost-saving topology, bidirectional communication, extensive information options, and standardization of the device functions and diagnostic functions.
All of the displayed versions can be implemented with a single or redundant system. Redundancy serves to increase the plant availability.
