I used to learn OMRON's PLC back in my diploma days, and its just ladder diagram, after i finished my diploma intern, the PLC program that my company used is mitsubishi GX Works3, its a big different to me since theres new program to be learned, such as structure diagram, function block etc, is there any website that i can learn or youtube channel/forum? i just wanted to find the correct way for me to learn, currently using the Q-series model:- R61P thanks :). I'm sorry if i asked a weird question :)
