Safety: Safety-related master-I-slave communication via PROFIBUS DP

  • Entry
  • Associated product(s)

 

Problem 
In safety-critical applications, the transfer of safety-related data (e.g. emergency stop signal) to a safety-related (failsafe) analysis unit (e.g. F-CPU) must be ensured, or you must be sure of exposing of errors in data transfer.

Solution
The bus systems PROFIBUS and PROFINET ensure reliable data transfer thanks to the PROFIsafe safety profile. Safety-related communication (F communication) is based on this and offers solution options for different scenarios with the F system S7 Distributed Safety.

This safety function example shows safety-related bidirectional master-I-slave communication via PROFIBUS DP.
