Failsafe organization block (F-OB)
1. Under "F-OB" assign a name for the F-OB; the default value is "FOB_RTG1".
2. For the F-runtime group created as default, the F-OB has the event class "Cyclic interrupt".
To change the event class of the F-OB of an already created F-runtime group, you must
delete the F-runtime group and recreate it.
Note
We recommend that you create the F-OB with event class "Cyclic interrupt" as "Cyclic
interrupt OB". As a consequence, the safety program is called at fixed time intervals.
