QUESTION:

How to evaluate a safety function by using SIMATIC S7 "standard output cards" switched off by the load voltage?

ANSWER:

ISO 13849-1
IEC 62061

Explanation for the application:

Following explanations attempt the possible evaluation of SIMATIC S7 standard output cards with IEC 62061 or ISO 13849-1.

The statements below do not contain any claim to completeness but should be a practical support in the comprehension and implementation of IEC 62061 or ISO 13849-1.

Attached you find a document which explains this issue detailled.
