Overview
In combination with the safety-related automation systems of the
SIMATIC PCS 7 process control system, the safety-related elec-
tronics modules of SIMATIC ET 200pro can be used to imple-
ment safety applications. The safety-related digital inputs record
the signal statuses from safety-related sensors, and generate
corresponding safety telegrams for the automation system. De-
pending on the safety telegrams of the automation system, the
safety-related digital outputs trigger safe shut-down procedures.
They are also responsible for monitoring short-circuits and
cross-circuits up to the actuator. The safe communication with
the automation systems is carried out over PROFIBUS with
PROFIsafe.
All modules are certified up to SIL 3 (IEC 61508) and Cat. 4
All modules are certified up to SIL 3 (IEC 61508) and Cat. 4
