commissioning phase of the SPL has not yet been completed. For an
error in the crosswise data comparison between NCK and PLC, a stop
response (Stop D or E) is not initiated.
Alarm display
Remedy for NCK: Activate the protective mechanisms by writing to MD
$MN_PREVENT_SYNACT_LOCK [0,1]. The number range of the
synchronous action IDs used in the SPL must be entered in this MD.
Remedy for the PLC: Activate the protective mechanisms by setting the
appropriate data bit in DB18.

To start the SPL in the protected state
($MN_PREVENT_SYNACT_LOCK[0,1] not equal to 0), at least one

functionality it is only possible to operate the SPL in the commissioning
state.
