I have a strategy with several RIOs. Just recently all the IO from the RIO was frozen in the HMI. In Debug, when I click on one of the RIO IO units it has an error:
I/O Unit not enabled. Previous communication failure may have disabled the unit automatically.
I have an IO_Enabler chart on this strategy and the IsIOUnitCommEnabled function is returning true even with that error. Is this supposed to work like this? How do I re-enable a RIO through the strategy after a communications failure?
