Bit
0
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
0
1
2
3
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.
● 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.
Behavior when the read-in disable is set
The behavior of the function "event-driven program call" in case of set read-in disable
(DB21, ... DBX6.1 = 1) can be set channel-specific with the machine data:
550

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.
Value Meaning
In the event-driven user program:
● After an activation through part program start:
0 The single-block processing is active
1 The single-block processing is suppressed
● After an activation by part program end:
0 The single-block processing is active
1 The single-block processing is suppressed
● After an activation by an operator panel reset:
0 The single-block processing is active
1 The single-block processing is suppressed
● After an activation by powering up:
0 The single-block processing is active
1 The single-block processing is suppressed
