Hi
I'm used to programming Siemens stuff but haven't touched AB for a few years now. I've got some simple mods to do to a program at work and wondered if anyone could set me straight on a few things... Firstly, how do the internal bits work? Is it..
I - Input
O - Output
B - Boolean bit (memory register bit)
N - Number? Like a marker word to hold an integer
Any others?
My second question is, does anyone know where I can find a simple run through of stuff like this specific to AB. As I mentioned, I'm up to speed with other PLC systems but just need pointers on AB.
Many thanks
