PI services
PI service ASUB
Initialization
With the ASUB PI service, it is possible to assign the interrupt numbers 1 and 2 fixed program names from the
PLC. Precondition for this is the existence of the programs
PLCASUP1_SPF
or
PLCASUP2_SPF
in the CMA
directory.
The following must be taken into account during the initialization:
• The PI service ASUB only has to be executed once after a restart and it is then kept.
• An initialization may only be performed when the channel is inactive.
• If a "power up" is configured as the initiating event for the events-triggered program call, initialization must
only be started after the end of the event-triggered program.
