Processor upgrade help

[MMfromDuPont 0]

I need some help as I have not had a whole lot of experience with modicon/momentum plc's. I am more a AB person. Anyway, I have a TSX 171 CCS 760 00-IEC processor that uses a modbus to ethernet bridge to connect to the network. It has a data bottleneck due to the modbus serial side of the bridge. I cannot have simultanious systems read data from the processor with causing delays. So I got a TSX 171 CCC 960 30-IEC processor to replace it which has ethernet built in to elliminate the bottleneck. When I change the processor I get an error "FBD CG SErvice on PLC failed! Error ID: OLI-21705. And no sub code. Does anyone have an idea on this, is the progam even compatible to use on this process. any advice would be appreciated.

The program for one should work on the other when you change the CPU type. Not sure why you are seeing an error.
