can you provide some links for visual diffing tools? 90% of the programs I write are PLC programs in the IEC 61131 function block language. I would love to be able to diff and merge.
PLC processors have come down so much in cost we have gone to a modular architecture where we have multiple CPUs in a plant each running an independent machine or part of the plant process partly so that one programmer can work on the program for 1 CPU without having to merge another programmer's changes.
I thought I might be able to get this open source PLC programming software which includes a function block renderer to read the unity XML program exports and then I could render the function block sections myself and diff them: http://www.beremiz.org/doc
Here is the only real product I've ever seen which has a module for matlab simulink diffing: https://www.diffplug.com/
Schneider does have the UnityDiff tool which has come a long way in the last couple years and it does pretty decent diffs but there is no way to generate them automatically that I know of. I have to open both versions of the program I want to diff and then run the diffing tool. Then the visual diff output can't be exported out of the unitydiff program. printing doesn't work. I should make some feature requests.

I thought this could be useful if I could use the PLC programming software (Schneider Unity) to export PDFs of the function block diagrams: http://www.evilmadscientist.com/2011/improving-open-source-h...
