CODESYS Forge (or short cforge) is a small tool which should help developers and users to use the services offered on CODESYS Forge. cforge is basically written in C# but can be extended with IronPython scripts. As it makes use of IronPython and MS Scripting, you might have problems running it on anything else than Windows.
cforge itself is packed as a CODESYS package. That leads to the most important prerequisite: CODESYS programming system has to be installed on your PC.
There are different ways of installing cforge to your PC.
To make full use of the cforge functionality, you need:
As it is a C# tool, just use Microsoft VisualStudio to run / attach to your local cforge instance.
There is a nice trick: just lay a file named "debug" (content does not matter) next to the cforge.exe and it will patiently wait when started (e.g. from the browser via a "cforge:" url), so that you have time to attach. Then just press Enter in the console (as it is mentioned there), and continue to debug.
Then you can even debug the IronPython scripts.
