I got a task to create an emulator which can connect to the PLC and literally make it possible for the PLC devs to develop their code way before the machine is built. Half of them completely refused the idea to use plc db values instead of the raw inputs so I can actually read and write as well.
All that refused are the 45+ guys.
The reasons:
~ You keep your little code on your computer.
~ I won't reference something twice
~ I never use DB's values as inputs
~ I am always working from paper sketch
~ We just do approximately and the commission guys will align.
~ This is waste of time.
