It is also possible to define untraceable sections in part program sections that the NC cannot yet
re-enter. When the program is interrupted, the NC notes the last block that was processed that
can then be searched for via the HMI user interface.
Syntax
IPTRLOCK
IPTRUNLOCK
The commands are located in a part program line and allow a programmable interruption
pointer
Meaning
IPTRLOCK: Start of untraceable program section
IPTRUNLOCK: End of untraceable program section
Both commands are only permitted in part programs, but not in synchronous actions.
Example
Nesting of untraceable program sections in two program levels with implicit "IPTRUNLOCK".
Implicit "IPTRUNLOCK" in subprogram 1 ends the untraceable section.
Program code Comment
N10010 IPTRLOCK()
N10020 R1 = R1 + 1
N10030 G4 F1 ; Hold block of the search-suppressed program sec-
tion starts.
...
N10040 subprogram2
... ; Interpretation of subprogram 2.
N20010 IPTRLOCK () ; Ineffective, repeated start.
...
N20020 IPTRUNLOCK () ; Ineffective, end at another level.
N20030 RET
...
N10060 R2 = R2 + 2
N10070 RET ; End of search-suppressed program section.
N100 G4 F2 ; Main program is continued.
The interruption pointer then produces an interruption at 100 again.
Further information
Acquiring and finding untraceable sections
Untraceable program sections are identified with language commands "IPTRLOCK" and
"IPTRUNLOCK".
