(PFH), the feedback DO1 need not be used. All safety-relevant errors that can occur in the SM100 result in the safe state. Faults have been excluded for protected cables (according to DIN EN ISO 13849-2:2008-09 and DIN EN 61800-5-2:2008-04). This applies to cables which are protected by a cable duct and installed inside the control cabinet.

Since the encoder is used to monitor the ramp now, it needs to be considered in the evaluation of the safety characteristics.
