Dear Forum Members,
I'm new to the world of plcs and their respective programming.
So I apologize for my ignorance, and thank you in advance for the help you can give me.
My question is the following, I am not the author of this program, I have already inherited the maintenance of this plc, and I am trying to understand the whole program, but since I am not the author of it, I do not have access to the symbols and descriptions of who conceived the program initially.
I can not understand how, by changing N9:6/1 or N9:6/5 to 1(On), I get N9:6/2 and O:0/0 and either N9:6/6 and O:0/1 in 1 (On)
Note: In Lad 2 I've some forced inputs just for testing.
Please see the attached program file
Thank you
Regards
Paulo
