Codesys Manual and Automatic Mode

[Thomas_Bray]

Hello, I know this might seem simple but however I cant seem to get my head around it!

What is the best way to have a manual and automatic mode and be able to have two seperate programs for both in Ladder Programming

Thank You

Thomas

in PLC_PRG program a switch to your manual_program
and another to automatic_program
so that way you will have 3 POU in your program.
what version are you using and what PLC is used.

Thank you for your reply, Im using Codesys 3.0, with a wago 750-8100 PLC, what is the best way to do a switch?

it depends on what you have, like a button, or a switch or maybe it is software.

i believe the best option is a selection switch, so when manual is on , plc won’t do anything, and when plc is on , manual can't do nothing
