Motion Control and IO with PLCs - EP12- MC_Absolute and MC_Relative 

Thanks! I'm currently doing some work on discrete event simulation in python. Otherwise, I'm sort of "out" of the PLC game unless someone wants to donate some allen bradley PLC hardware to me. I really don't care for AB much, so doing a tutorial series does not have me that enthusiastic. I'm not an expert in all that many things :P

Sunil Yadav I would but I've never used it, and never found a great use for it either. Some day.

Good question, hopefully he replies to this whenever he can. Im using a 7041 without an encoder for a project with a stepper motor and am questioning what the encoder part is used for if your able to make absolute and relative positions without one.

Yes, you can do it by calling 2 move instructions, but call them true every other scan, and it will adjust in realtime.
