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

9.8 Preventing program position for SERUPRO (IPTRLOCK,
9.8
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 parts program sections that the NCK
cannot yet re-enter. When a program is aborted the NCK remembers the last processed
block that can be traced from the HMI user interface.
Programming
N... IPTRLOCK
or
N... IPTRUNLOCK
Parameters
IPTRLOCK
IPTRUNLOCK
Both commands are only permitted in parts programs, but not in synchronous actions.
Example
Nesting of untraceable program sections in two program levels with implicit IPTRUNLOCK.
Implicit IPTRUNLOCK in subroutine 1 ends the untraceable section.
