9.8 9.8 Preventing program position for SERUPRO (IPTRLOCK,
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
The commands are programmed separately in a parts
program line and permit a programmable interruption pointer
Parameters
IPTRLOCK Start of untraceable program section
IPTRUNLOCK End of untraceable program section
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.
N10010 IPTRLOCK()
N10020 R1 = R1 + 1
N10030 G4 F1 ;hold block, the untraceable
... ;program section starts
N10040 subroutine2
... ;interpretation of subroutine 2
N20010 IPTRLOCK () ;no effect, restart
...
N20020 IPTRUNLOCK () ;no effect, end in other level
N20030 RET
...
N10060 R2 = R2 + 2
N10070 RET ;End of untraceable
;program section
N100 G4 F2 ;main program is continued
