so I just soldered my own RGB Arduino board but having troubles to sequence red green and blue, the message says it's an inappropriate device. Although it does work it just doesn't seem to sequence. I have the ground but can anyone tell me which part is the hot supposed to be in?

Belden Inc is a manufacturer of universal joints and drive shaft assemblies. In general, does anyone come across these in their line of work?

That Opto 22 Blog is great. Glad I found it.

Peer-to-Peer - how do YOU do it? post cool too. I wonder if termonolgy changed with the PAC, or remote I/O was just overlooked as a possible solution?

Does anyone know of an automation/controls engineering position open in the Tampa Bay area? Please msg me. I have just relocated to the area to attend USF for graduate studies. Looking for full time work. Thank you.

I've been using different types of sensors and systems for system integration and safety systems such as prox sensors and light curtains, Sink/Source, Ladder Logic and Fuzzy Logic for almost 20 years. I feel that there is still a lot that I have missed in other applications by sticking with a known/familiar few. But, unfortunately, that is the human nature.

Great, thanks again.

1756-ENBT should work just fine. I used the EN2T as an example but any of the EtherNet control modules will work.

Thanks Jim: I thought it was that simple, but wanted to do a little research via social network first. I did find when connecting just one laptop to ControlLogix, you can't have your computer set to auto default assign IP, you have to type in a manual IP address for your laptop. took me a while to figure out. So I was trying to see if there was any other little idiosyncrasies' I need to know beforehand. Also we have the 1756 - ENBT, that will work ok wont it?
