9.8 Block search Type 5 SERUPRO
Basic Functions
542 Function Manual, 09/2011, 6FC5397-0BP40-2BA0
Activation
"Self-acting SERUPRO" is activated via the HMI as a block search start for the Type 5 block search for target
channel "seruproMasterChan".
No search target is specified for dependent channels started from the target channel.
9.8.5 Inhibit specific part of the program in the part program for SERUPRO
Programmed interrupt pointer
As a general rule, only the user of the machine knows the mechanical situation that is currently being executed in
the program. The user can use a "programmable interrupt pointer" to suppress SERUPRO at a particular point in
the program where complex mechanical conditions prevail to enable user intervention.
Through suitable manipulation of the interrupt pointer, it is possible, with "search for interrupt point", to resume
processing to the search-suppressed location prior to the search-suppressed location. Search-suppressed areas
can also be defined in areas of the part program in which the NCK is not allowed to resume processing.
The last block processed before the search-suppressed target area is used as a search pointer.
Input program section
The IPTRLOCK and IPTRUNLOCK language commands mark search-suppressed sections of the program.
These language commands cannot be used in synchronized actions.
IPTRLOCK
Freezes the interrupt pointer at the next "machine function block". This block is referred to below as the Hold
block. If a program abort occurs after IPTRLOCK, then the hold block is used as a search pointer.
Machine function block
Is a single block (SBL1) that can be executed in the main run with a stop after each function block.
IPTRUNLOCK
The interrupt pointer is repositioned at the current block at the time of the interrupt for the subsequent program
section.
A search-suppressed area in the part program can be detected using the $P_IPRTLOCK variable.
IPTRLOCK Start of search-suppressed program section
IPTRUNLOCK End of search-suppressed program section
Note
When a search target is found, the interrupt pointer is set to the hold block. The block search
can be repeated for a new search target with the same hold block.
