Clearly I misread who posted the comment about PV600’s sucking. My bad and I apologize to the OP. I stand by my statements that you need to know how to work with AB products in the industrial automation field so I encourage “thiefgold0913” to stick with it and learn AB stuff (as well as others). As several have said I would start with AB’s free stuff however I’d start with the MicroLogix stuff rather than the Micro 800. In my view the MicroLogix are easier to learn and work with. Good catch badger.
