Hi

I have currently a customer which bought a line from EMEA region. They are trying to convert it to NAFTA, the main problem is that NAFTA specs require to have more logic on it. In order to support debug tools and system. 

Currently I have the biggest PLC from 319 F-3PN/DP series. 

I want to know what are my options in order to reduce the PLC program without retyping the logic. I mean I could add some instructions like move DB to Load memory and the load them back but I don't know if it will really help me. 

Thanks
