To determine the achieved Performance Level, the safety function is separated into sensor, logic and actuator. Each of these subsystems contributes to the safety function. EN ISO 13849-1 and EN/IEC 62061 requires calculations. To do this in a manageable way a software tool provides excellent help. Pilz provides a user-friendly calculation tool (PAScal) for this purpose.
