Iner,
I worked for two oem's over a 20 year span, never the same job or machine twice, always a new machine to be built.
I program ladder logic and document it in such a way that all maintenance personnel with a basic knowledge of plc programming can follow.
you can see the program execute in a sequential order, rung after rung.
nothing fancy, I just keep it simple for everyone.
when I did get a call, I know maintenance has a problem and they can explain what the machine is doing and where it stops. it typically takes less then 30 minutes to resolve the issue.
maintenance gets the machine running, production is going, management is happy, my boss is happy.
yes, you can program the machine in 50 rungs where I might use 75-100 rungs, or use sequencers, sfc programming, fuzzy logic and so on, but why write code that only you understand?
