As long as the protective mechanisms for the NCK-SPL have not been
activated (MN_PREVENT_SYNACT_LOCK[0.1] equal to 0), Alarm 27095 is
displayed when crosswise data comparison between the NCK and the PLC
starts. This alarm can be acknowledged with NCK key so that the SPL can be
commissioned.

Starting the NCK-SPL using the PROG_EVENT mechanism

(from SW 6.4.15)
From software release 6.4.15, the NCK-SPL can be started using the
PROG_EVENT mechanism.
The cycle PROG_EVENT.SPF (saved under manufacturer cycles
..\DH\CMA.DIR) is started when a specific event occurs (event-controlled
program call).
Using the machine MD 20108 $MC_PROG_EVENT_MASK for this
PROG_EVENT mechanism, certain events are enabled on a specific channel
basis which then initiate that the cycle is started.
The following events can be activated as start condition:
•
•
•
•
The start condition at run-up (bit 3 ==1) must be active in order to start the NCK
SPL (SAFE.SPF) via PROG_EVENT.SPF. The ability to start the NCK SPL via
this mechanism as replacement for the PLC controlled call via FB4/FC9 is
available from NCU system software 6.4.15 onwards.

Caution
The protective mechanisms that prevent changes to the NCK-SPL file and the
NCK-SPL statements only take effect if
MD $MN_PREVENT_SYNACT_LOCK[0,1] is not equal to 0
The machine manufacturer must ensure that
the protective mechanisms are activated no later than after completion of the
acceptance test and
the values set in MD $MN_PREVENT_SYNACT_LOCK[0,1] have been
documented in the acceptance report.
After commissioning has been completed, the access rights to the SAFE.SPF
file must be set to the correct access level for writing/reading/deleting access
operations (manufacturer or service).
