CODESYS v2.3 version

Hello @AllfourYR, we used the WAGO-flavored CODESYS version 2.3.9.44.

I am very appreciate your replay. I have a question, why do not use CODESYS V3.5 to do research?

hi, I have the same questions. I use CODESYS V3.5 ,but have not found the *prg files, only the *app file. but the *.app file have not the same format with *prg. can you help me?

@AllfourYR there are many reasons behind our choice of devices and software that fall out of scope here. At the moment, ICSREF only handles CODESYS v2.3 binaries.

@AllfourYR, @hjzmc From preliminary analyses on CODESYS v3.5 I also found that *.app files are employed in the place of PRG files. These *.app files include several configurations for the target devices, including HTML for the webserver, graphics and visualization files, along with the compiled application binary (the application binary is somewhat equivalent to the *.PRG files). I think of it as a "combined" configuration file that includes all the target details in one file. It should be feasible to carve out the compiled application binary from the *.app files and apply ICSREF on them; since the mechanics of the underlying compiler (i.e., the CODESYS compiler) do not change significantly between versions, the tool should, perhaps with minor tweaks, apply to the newer app files.

One idea is to have a separate extractor that carves out the prg equivalent from app files and then apply ICSREF on them; another idea is to incorporate such an extractor into ICSREF directly, and recognize whether an app or a prg file is provided and apply the corresponding analyses. In either case, we welcome pull requests for these features. ICSREF development is ongoing with this feature being in our list; however we don't have a definitive timeline for this feature.

Thanks very much！！

thank you!

If i use CODESYS V3.5, i can generate a boot project by CODESYS Control for Raspberry PI. If i want to generate a boot project in CODESYS V2.3, i have to use some others PLC, like WAGO ?

@AllfourYR For compiling projects for different targets CODESYS v2.3 uses the concept of "Targets", so you would need to have the appropriate target files (*.trg in the CODESYS installation directory). These are specific to each target device (in your case Raspberry Pi). I am not certain if Raspberry Pi targets are available for CODESYS v2.3, I would recommend checking the codesys website/forums for an answer to this question.

@tkeliris Sorry to bother you again, I have been trying my best to find WAGO 750-881's target file , but I can not get it. Can you give me some help ?

@AllfourYR Sorry for the (very) late reply. Target files are bundled with licensed versions of CODESYS and therefore cannot be redistributed.
