Click here for Ignition Version Compatibility


Whilst we run rigorous automated testing for each of our modules, we always recommend that you thoroughly test new module versions in a test environment before releasing to production
When installing Cirrus Link modules in Ignition, all module versions must match. If they are not, class loading issues may result in system instability. Always make sure all Cirrus Link module versions match in an Ignition Gateway.
