We have an OPC UA Client Connection to a PLC that hosts its own OPC UA server as a more efficient method of communication than using Ignition's built-in drivers. There are situations in which the server goes down and comes back up i.e. is temporarily disconnected. When the connection is faulted/disconnected, we have overlays on every related indicator in the HMI (Vision).
When the server spins back up, the connection is re-established automatically and the indicators that are driven by the PLC (i.e. the ones that are continuously updating) return to normal appearance with the overlays being removed.
Issue: Indicators that do not get continuously updated do not get refreshed/do not have their overlays removed. These indicators have changes that are either intermittent or driven by operator action. Operators will not interact with these values because they appear to have no communication. If I go into the Gateway Webpage > OPC Connections > Edit and toggled "Enabled" off and then on again, all indicators refresh and appear functional.
On various occasions, the persistence of overlays after communication has been restored has been confusing to operators. It is not optimal for an Ignition administrator to manually reset the connection when this occurs (separate from figuring out how to reduce intermittency on the PLC side). Is there some way to auto-refresh all tags upon re-established connection or to otherwise programmatically refresh connection status?
