Good evening everyone,
My first GE Project. I am using a GE VersaMax Nano(IC200UDD040-AB) using PME 9.0. The PLC has the IC200UEM001 Ethernet card added to it.
Everything was working fine, I found a small error in my %R registers so I made the change and then downloaded the project.
Now when I go online with the PLC I don't see any data in the program blocks like I did before. There are red question mark boxes by each contact and coil. There is a message on the lower right hand part of the screen that flashes "**WAITING FOR DATA FROM CONTROLLER**".
I know the PME is going online with the controller as it says so in the Feedback Zone. I know the PLC is in Run mode as the HMI connected to it works just fine. I can ping it and the HMI can connect to it over the Ethernet so I know all that is working.
Any ideas what happened and how to get this back to working like it was?
Thanks in advance.
