Detailed description
2.7 Program operation mode
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 part program start:
• /_N_CMA_DIR/_N_PROG_EVENT_SPF is executed as a subroutine.
Errorin the case of operator panel reset or after power-up:
• If an error is present when the operator panel is reset or after powerup EMERGENCY
The following always applies to power up:
• The power up event occurs in all channels at the same time.

Bit 2 = 1 is set after operator panel Reset event
Bit 3 = 1 is set after Power-up event
Bit 4 = 1 is set after first start after search run event
For Bit0 = 1 (program event after part program start) the following limitation applies:
If the program event ends with the part program command "RET", then 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.
A return by means of REPOS command is not permitted and triggers 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.
