Thats a good point all the schooling is great but until you actually work with one put in the program and debug it, its all window dressing.
The small SMCCs are nice to learn on, but logic programming is alot more involved than just ladder logic. the smaller ones are merely 'relay replacers' and have some nice features such as a timing functions.
I worked on a job involving an ' Air-Knife ' whicch used both plc's and pcs and they had to work in conjunction with each other. We had to get Reliance Electric involved, and their Servo motors and some major DC drives were incorporated too..
And when all was said and done there were a couple Thousand pages of software involved with job.
But the basic getting into it can be done with a small hand-held unit. But what I dont like is GEs software is different from say A&B. Even the terminology is unique to AB.
