Nontrivial IEC 61131-3 Code Examples

I am currently developing a method for symbolically executing and testing IEC 61131-3 applications. For evaluating my approach, I require non-trivial programs written in any of the languages defined in the standard.

Are there any openly accessible code bases I could use for this?

A very good source for examples is Beckhoff's information system which is also available for download.

You can find good examples of different methods for example under different libraries.

The OSCAT libraries is the biggest open code base written in IEC61131-3 afaik. They provide different libraries for different use cases and for different plc vendors

Furthermore there are some example programs available on Beckhoff Infosys. For almost every library they provide a sample section. One of the biggest samples is the OOP extension sample (OOP extensions are included in the new version of IEC61131-3, not sure if you are interested in it).

Another source of examples is the Codesys Store. They have some free and some paid examples.

And one more I like (but its only in german). M. Seitz the author of a good plc programming book provides some accompanying samples, one of them a bit bigger (coffee machine). There is also a simulation and control library available.
