Glad to hear that you were able to connect Ok via the IP address.
The question about the strategy has a few more questions attached.
You already answered the first one, and that is if any hardware is attached to the I/O. If there were, then yes, major damage could happen as the different strategies have different I/O configurations and will drive the I/O in different (unintended) ways.
The main question that popped into my mind however is if you have the current control strategy backed up?
If you don’t, and you download the learning strategy, you will lose your control strategy forever.
Right click on your controller in PAC Terminal (handy little utility that one) and select Upload, then see if there is a strategy archive stored the controller.
If so, go ahead and upload it onto your computer and back it up in three different physical locations. (USB stick, and Network drive for example).
If there is no strategy archive stored on your controller DO NOT download the learning center strategy and over write it. (Hope I caught you in time!).
