9.9 Program operation mode
Behavior when starting a user ASUB
The behavior of the function "event-driven program call" upon start of a user ASUB from the channel statu reset
can be set channel-specific with the machine data:
MD20109 $MC_PROG_EVENT_MASK_PROPERTIES
Bit Value Description
0 0 The occurrence of an event set with MD20108 (part program start, part program end
and/or operator panel reset) leads to the activation of the event-driven user
program.
1 The occurrence of an event set with MD20108 does not lead to the activation of the
event-driven user program.
Behavior when the single block processing is set
The behavior of the function "event-driven program call" in case of set single block processing can be set
channel-specific with the machine data:
MD20106 $MC_PROG_EVENT_IGN_SINGLEBLOCK
Bit Value Description
In the event-driven user program:
0 • after an activation through part program start
0 the single block processing is effective.
1 the single block processing is suppressed.
1 • after an activation through part program end
0 the single block processing is effective.
1 the single block processing is suppressed.
2 • after an activation through operator panel reset:
0 the single block processing is effective.
1 the single block processing is suppressed.
3 • after an activation through power-up
0 the single block processing is effective.
1 the single block processing is suppressed.
If the single block processing is suppressed, then the event-driven user program is processed without
interruption.
Note
MD20106 $MC_PROG_EVENT_IGN_SINGLEBLOCK affects all single block processing
types.
Note
The single block processing in the event-driven user program can be switched-off through
the following configuration:
MD10702 $MN_IGNORE_SINGLEBLOCK_MASK (Prevent single block stop) bit 0 = 1
The differentiated settings in MD20106 $MC_PROG_EVENT_IGN_SINGLEBLOCK are then
ineffective.
