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.

Load the state of input I10 into the logic

accumulator.

If logic accumulator =0, jump to LBL 100.

Interrogate the status of the submit program and

load it into the word accumulator.

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.

If logic accumulator =1, jump to LBL 100.

Call submit Program 300.

Save the identifier of the submit program in byte

Load the state of input I11 into the logic

accumulator.

If logic accumulator =0, jump to LBL 110 (skip the

program cancellation).

Cancel the submit program.

End of the main program.

Label: Beginning of the submit program.

End of the submit program.

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
