In ETS Test Setup, the PROFIsafe tests are sometimes successful, sometimes failed - Why?

[Webinar_Question]

In ETS Test Setup, the PROFIsafe tests are sometimes successful, sometimes failed (if repeated without changing anything). The failure is due to PROFIsafe watchdog expiration. What could be the reason for this instable behavior?

Without having further details, it might be due to an F_WD_Time setting that is too low. This should be set to at least 1000 ms. The Automated RT Tester itself uses a cycle time of 32 ms.
