Example:
This example also applies to the commands SUBM and RPLY.
Depending on input I10, submit the subroutine with the label LBL 300 to the
NC for processing. In addition, check the execution of the subroutine in the
main program with the RPLY command, and cancel it with the CAN command,
depending on input I11.
Always insert submit programs, like any module, at the end of the main
program. In this case, the content of the submit program could be a display in
the PLC window that is realizable through permanently assigned PLC
modules.
Function STL
Load the state of input I10 into the logic
accumulator. L I10
If logic accumulator =0, jump to LBL 100. JPF 100
Interrogate the status of the submit program and
load it into the word accumulator. RPLY B128
If the word accumulator is not equal to 0, i.e., the
submit program has already been transferred to the
NC for processing, set the logic accumulator to 1. <> K+0
If logic accumulator =1, jump to LBL 100. JPT 100
Call submit Program 300. SUBM 300
Save the identifier of the submit program in byte
128. = B128
Label LBL 100
Load the state of input I11 into the logic
accumulator. L I11
If logic accumulator =0, jump to LBL 110 (skip the
program cancellation). JPF 110
Cancel the submit program. CAN B128
Label LBL 110
End of the main program. EM
Label: Beginning of the submit program. LBL 300
End of the submit program. EM
