If either of the following conditions occur after a PAC Control strategy has run, the control engine will not be able to enable communication to the affected groov I/O Unit and a -93 (I/O Unit Disabled) error will be posted to the control engine’s message queue:
- Power is cycled on a remote groov I/O unit.
- You Reset I/O to Defaults using groov Manage (Home > I/O > I/O Unit Configuration and Tools > Configuration > Reset I/O to Defaults)
This issue does not occur the first time the PAC Control strategy is run after downloading the strategy to the control engine.
Clear control engine RAM and then download the strategy again.
