9.3 Program Section Repeats
The beginning of a program section repeat is marked by the label
LBL. The end of a program section repeat is identified by
CALL LBL /REP.
Operating sequence
1 The TNC executes the part program up to the end of the program
section (CALL LBL /REP)
2 Then the program section between the called LBL and the label
call is repeated the number of times entered after REP.
3 The TNC then resumes the part program after the last repetition.
Programming notes
■
You can repeat a program section up to 65 534 times in
succession.
■
The number behind the slash after REP indicates the number of
repetitions remaining to be run.
■
The total number of times the program section is executed is
always one more than the programmed number of repeats.
