The boss handed me a laptop,cables and gx-develeper-fx and said upload parameters from our fx,fn1n,fx2n and fx1s plcs. We probably have 25 or 30 in the old factory. Most of them probably only use 7 rungs. I tried uploading from 3 different machines and got what is the keyword? The company that programed the plcs say they dont use psaawords. I got a new fx2n off the shelf and everything uploaded just fine. What are my options?
