Control data filter
Unused functions in the control data of the safety bus must be set to "Inhibit" via the parameter
"S bus: Control data filter" ( C15113 ). Then, these functions cannot be activated anymore via the
safety bus independently of the transmitted control data.
[3-2] Function example - filter
From version 1.2 of the drive-based safety system, the filtered control data is displayed in the
parameter "S bus: Control data display" ( C15115 ):
 Control data, incoming
(0 = active, 1 = inactive)
 Control data filter
(Selection in the »Engineer«: a = "pass through", i = "inhibit")
