The table below lists the functional blocks that offer these parameters.
To configure a startup inhibit for a specific safe output, for example, this output must be
directly connected in the safety logic to the output of a safe functional block, for which the
startup inhibit is set via the parameters.
Example In the example below, EmergencyStop as well as a startup inhibit (S_RES parameter =
FALSE) and a restart inhibit (A_RES = FALSE) are specified for the safe functional block.
The OUT enable output for the functional block is connected directly to safe output O0,
where O0 offers a restart inhibit and a startup inhibit. (EmergencyStop executes stop
category 0 at the output, which is also transmitted to O0 by the direct connection.)
