Standard Function Blocks
Operating modes
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.
