Thanks for the direction. I contacted Schneider and we are on our way. Much Appreciated everyone!!

Thanks much for the help. I found out that it is actually Proworxs. Anyone know where I would go to buy it? I did not see it available on Schneiders automation and products software web site.

Thank you! That certainly clears up alot! I guess my only option would be to try to access with each of those? Any idea How I might determine what was used to program the Momentum?

Hello, I'm new to this forum and have just recently gotten back into PLC programming after about a 10 year break. But here's my problem. I have a customer with a distributed i/o system with 3 Modicon 171ccc96030 several miles apart, communicating via leased lines and data sync modems. I was TOLD the program was done with Twido soft approx. 5-6 years ago. I have not been able to access the program ...I have tried to use Twido suite which I believe should be able to access earlier versions of twido soft. The closest I get is the error message " The controller connected to the PC is not supported". I guess I am wonderring several things. Is there a way for me to figure out what program is actually there? Should I be able to access the program from ANY of the 171ccc96030's or must I figure out which might be the master? Any suggestions as to what my next step might be? I appreciate the help. Thank you much
