I am currently programming an IDEC OpenNet PLC, which uses the WindLDR software. My question is, if I want to repeat a process several times, is there a way to program a subroutine or a loop with a counter by using index addressing in the ladder logic programming? If so, how do I do this? If it is not possible, can I write the program in C++ and then compile it into the ladder software language?

Ladder Logic w/ loops or subroutines?

I do not know the PLC you mention, but almost any PLC supports FOR-NEXT type loops, conditional jumps, subroutines and indexed addressing.
A certain type PLC may miss one of the mentioned.
For instance, discontinued Mitsubishi FX0 series did not support subroutines.
