Start-up disabler (input parameter

AuSt)

If the start-up disabler is active (

AuSt = 0), you will need to reset after each

• PSS warm start

• PSS cold start or

• SafetyBUS p: I/O-Group start (input parameter

GRP must be assigned

the status flags of the relevant I/O-Groups)

Only then can the enable be given. If a function test is also required (see
input parameter

NoFT), this must first be completed without error and then

reset. If no other errors are present, the enable will be set.

If the start-up disabler is not active (

AuSt = 1), the enable will be set

directly if no more errors are present. If a function test is required (see
input parameter

NoFT), this must first be completed without error.
