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?

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.
Comment by Donald Fitchett on March 3, 2010 at 10:52am
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?
Comment by Jim Lutzo on March 3, 2010 at 7:42am
Donald,

Any of the EtherNet versions of the ControlLogix communication modules should work for this application. The module (e.g. 1756-EN2T) would be installed in the same chassis as the controller, and connected with a standard ethernet cable to one of the router's ports. You would then connect from any laptop to the 1756-EN2T by whatever IP address you give it, over the chassis backplane to the slot where the controller resides.
