mitsibushi A series PLC programming using GX IEC Developer

[mitsibushiman]

I have recently started using GX IEC Developer V4 for programming plc programs for an A2SH(S1) CPU. But the problem i now have is that i am trying to upload a program from the cpu into the developer software in ladder format, however it will not allow me to do so , it will only upload in melsec instruction list, which is no use to me for monitoring purposes, does anyone have any idea how to do this???. Whwn i try to upload from cpu to software in symbolic mode (ladder) i get an error message along the lines of GX Developer is unable to upload symbolic information from CPU as none is availible do you wish to upload in melsec IL(instruction list). Or is there a way in developer to convert melsec IL to Ladder??

Any help much appreciated

Unfortunately, you will not be able to upload Ladder unless the code was downloaded with IEC developer, the symbolic information is the info that says how to display ladder, functions, function blocks etc.

If you are adding code, then stick what you have into a function block (if you know it works ok) call this in a POU and add your code around that, or stick that in another function block ( because you can prevent anyone else having access if required)
