4.55 PARAMETERS OF SEQUENCE NUMBER COMPARISON
AND STOP
8341 Program number subject to comparison and stop
[Input type] Setting input
[Data type] 2-word path
[Valid data range] 1 to 99999999
This parameter sets the program number, including a sequence number,
subject to sequence number comparison and stop. Parameter
No.8342 is used to set a sequence number subject to check
termination.
8342 Sequence number subject to comparison and stop
[Input type] Setting input
[Data type] 2-word path
[Valid data range] 0 to 99999999
This parameter sets the sequence number subject to sequence number
comparison and stop.
If the block containing the sequence number set with this parameter is
executed while the program set with parameter No.8341 is being
executed, a single block stop occurs after the block is executed. At this
time, the setting is automatically set to -1.
NOTE
1 When -1 is set in parameter No. 8342, comparison
and stop is disabled.
2 Comparison and stop cannot be performed using a
sequence number contained in a block (such as a
macro statement, M98, and M99) that is processed
only inside the CNC.
3 When a match is found with the sequence number
of a block (such as an L specification of a canned
cycle) that specifies the number of repeats,
operation stops after executing as many times as
the number of repeats.
4 If the sequence number set in parameter No. 8342
appears more than once in the program, operation
stops at the block where the first match is found in
the order of execution.
