CfUnit is verified on the following runtime versions (not exhaustive). If you have successfully ran CfUnit on a runtime system that is not yet listed here, please drop us an email and let us know so others can benefit from it too.
Sadly, we cannot guarantee this library to be compatible with all systems, though we strive for high inter-compatibility. All vanilla CODESYS runtimes from v3.5.14.x or higher are supported. OEM runtimes listed (or higher) are supported, but mileage may vary. Older runtime support in theory can work starting from 188.8.131.52 ( again, your mileage may vary, so try at your own luck). In case of older runtimes, some library references/dependencies should be swapped for older ones.
