Starting The Nck–Spl Using The Prog_Event Mechanism - Siemens SINUMERIK 840D sl Function Manual

05.08
SPL start without axial safety enable
When the machine is being commissioned, the SPL must be started without
enabling axis–specific safety–related functions.
It is therefore possible to handle general machine functions (hydraulics,
Emergency Stop) before the axis is commissioned.
This is only possible in the commissioning state of the SPL ($MN_PRE-
VENT_SYNACT_LOCK[0,1]==0 and DB18.DBX36.0==0).
This state is displayed when the SPL starts using Alarm 27095 "%1 SPL protection
not activated".
If an attempt is made to start the SPL in the protective state (after commissioning
has been completed) without the axial safety function having been activated, then
Alarm 27096 is output. The SPL is started if the SPL crosswise data comparison is
not activated.
7.3.5 Starting the NCK–SPL using the PROG_EVENT mechanism
The NCK–SPL can also be started using the PROG_EVENT mechanism.
The PROG_EVENT.SPF cycle (saved under manufacturer cycles ..\DH\CMA.DIR)
is started when a specific event occurs (event–controlled program call).
Using the machine data MD 20108 $MC_PROG_EVENT_MASK, for this
PROG_EVENT mechanism, certain events are enabled on a specific channel–for–
channel basis which then start the cycle.
The following events can be activated as start condition:
S Start of a part program
S End of a part program
S Operator panel reset
S Boot
The start condition when booting (bit 3 ==1) must be active in order to start the
NCK–SPL (SAFE.SPF) via PROG_EVENT.SPF.
