Thanks again. Now I am much understanded the whole structure of Microcomputer PID program. Wonder where to get the full explaination of usage of microcomputer program i.e. Standard PID control.

Since I don't have any reference materials of **.OBJ, can you explain more in detail? My program look like this: -----[mov h294 d9090] -----[sub h78] this type instruction have more 5 within the program. -----[mov h1f4 d9090] -----[sub h75] this type instruction have 1 within the program.

Thanks. I just opened the file with Medoc 2.3 but how to view the microcomputer program section? And where I can get those .OBJ files and its source. Need advice!

Thanks Gambit, I have the Medoc ver 2.3 but there is no any ***.obj files. Where I can get it? Is possible to upload from A2N PLC including microcomputer code? What software to be used as the GX Developer was unable to perform this task. I need to upload from existing system to confirm and verify the code before any conversion. Need advice. Thanks.

Hi everyone, I need to convert a old A2N PLC into Q series. But there are some microcomputer program inside the A2N which mainly for PID control. Does anyone know how to upload the microcomputer program? And is it possible to convert everything from A2N to Q? Thanks.
