Prevent Program Position For Serupro (Iptrlock, Iptrunlock) - Siemens SINUMERIK 840D sl Programming Manual

Path traversing behavior

10.8 Prevent program position for SERUPRO (IPTRLOCK, IPTRUNLOCK)

System variables
A stop delay section can be detected in the part program with $P_DELAYFST. If bit 0 of the
system variables is set to 1, part program processing is now in a stop delay section.
A stop delay section can be detected in synchronized actions with $AC_DELAYFST. If bit 0
of the system variables is set to 1, part program processing is now in a stop delay section.
Compatibility
The default setting of machine data MD11550 $MN_STOP_MODE_MASK bit 0 = 0 triggers
implicit stop delay section during the G code group G331/G332 and when a path movement
or G4 is programmed.
Bit 0 = 1 permits a stop during a G code group G331/G332 and when a path movement or
G4 is programmed. The
delay section.

IPTRUNLOCK)
Function
For some complicated mechanical situations on the machine it is necessary to the stop block
search SERUPRO.
By using a programmable interruption pointer it is possible to intervene before an
untraceable point with "Search at point of interruption".
It is also possible to define untraceable sections in part program sections that the NCK
cannot yet re-enter. When the program is interrupted, the NCK notes the last block that was
processed that can then be searched for via the HMI operator interface.
Syntax
IPTRLOCK
IPTRUNLOCK
The commands are located in a part program line and allow a programmable interruption
pointer
Meaning
IPTRLOCK
IPTRUNLOCK
Both commands are only permitted in part programs, but not in synchronous actions.
