• The read-in disable and single-block processing behavior can be controlled using
No sequences for start/end of part program are passed:
• If a user ASUB is started from the reset status, the described sequences for the event for
• Settable Prog-Event properties
When starting a part program:
• /_N_CMA_DIR/_N_PROG_EVENT_SPF is executed as a subroutine.
Errors in the case of operator panel reset or after powerup:
• If an error is present when the operator panel is reset or after powerup EMERGENCY
The following always applies to powerup:
• The powerup event occurs in all channels at the same time.

machine data MD20106 $MC_PROG_EVENT_IGN_SINGLEBLOCK and
MD20107 $MC_PROG_EVENT_IGN_INHIBIT as follows.
MD20106 $MC_PROG_EVENT_IGN_SINGLEBLOCK
_N_PROG_EVENT_SPF makes a block change in spite of single-block mode without an
additional Start if
Bit 0 = 1 is set after the part program start event
Bit 1 = 1 is set after the part program end event
Bit 2 = 1 is set after the operator panel reset event
Bit 3 = 1 is set after the power-up event
Bit 4 = 1 is set after the first start after search event
MD 20107: PROG_EVENT_IGN_INHIBIT
_N_PROG_EVENT_SPF makes a block change in spite of read-in disable if
Bit 0 = 1 is set after the part program start event
Bit 1 = 1 is set after the part program end event
Bit 2 = 1 is set after the operator panel reset event
Bit 3 = 1 is set after the power-up event
Bit 4 = 1 is set after the first start after search event
The following restriction applies to Bit0 == 1(prog-event after part program start):
If the prog-event is ended with part program command "RET", RET always leads to an
executable block (analogous to M17).
There is no new behavior for Bit0 == 0, i.e., RET is interpreted in the interpreter and does
not lead to an "executable block".
start/end of part program are not passed.
Machine data MD20109 $MC_PROG_EVENT_MASK_PROPERTIES can be used to
define further properties of "event-driven program calls" for specific channels in SW 6.3
and higher:
– Bit0 = 0: An ASUB started from the RESET channel state is followed
by an "event-driven program call" as in earlier versions
– Bit0 = 1: An ASUB started from the RESET channel state is not followed
by an "event-driven program call"
_N_PROG_EVENT_SPF must be ended with M17 or RET.
No return using the REPOS command is permitted; this will generate Alarm 16020
"Repositioning not possible".
STOP or Mode group/NCKContinue, then _N_PROG_EVENT_SPF will only be processed
after EMERGENCY STOP has been acknowledged or the error has been acknowledged
in all channels.
