Introduction

Devices with integrated safety option support parallel operation of standard and safe communication via a bus system or network. Safe communication is possible via PROFIsafe.

PROFIsafe communication is possible via PROFINET. To that end, the basic device with integrated safety option must be connected to a fail-safe controller (F-PLC) via PROFINET.

To control safety subfunctions and to evaluate the responses from the safety option via PROFIsafe, the assignment of the individual bits in the F-process input data/output data must be taken into consideration.
