Classicladder Subroutines

Hi all,

I am working on a CNC Lathe that has a lot of functions that I want to handle in classic ladder by compartmentalizing things into sub routines. Is there a way to increase the number of call coils for subroutines? I had hoped that by increasing numSections that this would happen but, apparently not...

Kind Regards,
Dan

The number of sub routines is not configurable - other then modifing and recompiling the program.
Depending on what you are doing - classicladder also supports sequential programming.
Sequential programming builds a state machine that runs other ladder routines as each state transitions.
Might be cleaner - might be a pain - i don't think it's used much.

Sequential programming does seem to have potential and when you say "state machine" l can't help but think that that type of ladder logic may be useful with the ethercat hal-driver...I need to dig deeper. However for now, I found that by using the Mission pattern I have enough sub-routines to handle everything.

Should I choose to "modify and recompile" any idea what/where that file is called. I'm running the development files anyways. 10 subroutines for a state machine doesn't seem like much.

Kind regards,
Dan
