I'm working to fix/improve the functioning of a program running on an a PLC5/40E. I think high Scan Times are a big problem with this current program. ((Backstory: someone added some quasi motion control, and it sort of worked for a while. Now that it's broken, the operators of this machine want it back. )) I'll keep my question simple, PLC5's are new to me:
There are 36 rungs with CPT instructions as the sole output, a third of these instruction are executed every scan. I'm going to replace them with MOV instructions.
My question is, is there any sneaky PLC5 reason to do a CPT instead of a MOV? Is there a better way to do this?
The CPT instructions that execute move integer values to a data file used by the HMI to control the coloration of touchscreen buttons.
Thank you for your time.
PS: I'm new-ish to this forum, please feel free to let me know if my question was asked correctly or not.
