Starting the NCK- -SPL via PROG_EVENT
Note
This function is an option, and is not included as standard in Safety Integrated.
The NCK--SPL can also be started using the PROG_EVENT mechanism.
The PROG_EVENT.SPF cycle (saved under manufacturer cycles ..DHCMA.DIR)
is started when a specific event occurs (event--controlled program call).
Using 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 start condition when booting (bit 3 ==1) must be active in order to start the
NCK--SPL (SAFE.SPL) via PROG_EVENT.SPF.
Note
When starting the NCK--SPL (SAFE.SPF), it is important that the PROG_EVENT
mechanism was started through channel 1. This must be taken into account when
parameterizing the channel--specific machine data MD20108
$MC_PROG_EVENT_MASK .
Using the system variable $P_PROG_EVENT, in PROG_EVENT.SPF it can be
interrogated as to which event activated the call:
S Start of a part program
S End of a part program
S Operator panel reset
S Boot
For the PROG_EVENT.SPF cycle, MD11602 $MN_ASUP_START_MASK,
PROG_EVENT.SPF and the SAFE.SPF are taken into account, which can be used
to set that stop reasons for the sequence are ignored.
In order to be able to use $MC_PROG_EVENT_MASK and
$MN_ASUP_START_MASK, the "Cross--mode actions" option must be activated.
