Hi all,
One of my clients has a GE Fanuc 90-30 that communicates to an RX3i via a Genius module. The original integration was done by someone other than me (let's call him programmer A), but since integration another programmer (programmer B) has done additional modifications. In fact, programmer B is the one who set up the Genius modules as they weren't a part of the original integration effort.
The problem is, programmer B is pretty much impossible to get ahold of despite multiple attempts. So I was able to get a copy of programmer A's code, but it doesn't have the Genius comms code as it's older.
So far as I understand from searching through the forums, if you connect to a 90-30 and "upload" the code from the controller to your PC, you'll get the ladder logic but no comments and register names. Since I have the programmer A code, does that mean if I try to connect to the PLC it'll show that the project doesn't match the code that's running, and if I upload I'll retain the existing code and the "new" code will be grabbed, but no comments or register names will come along with it?
I know this seems like a simple question, I just don't want to mess anything up by connecting to the PLC and unwittingly break something.
