In about four months I will be getting my wing worked on and I will be off of work for possibly 3 months. What I was thinking was I could use this time to try to acquire some new plc skills. I am very week in the area of analog, servo programming controls, etc. Does anybody have any idea on a way I could (inexpensively), set up some kind of training set up. I have an slc I can work with. I don't know what cards I need or what. Any ideas would be greatly appreciated!
