Note: If you are using an OPC UA DA Collector with unsolicited data collection and have collector compression disabled, all new values should produce an exception. When the OPC UA DA Collector is doing unsolicited collection, the deadband percentage is determined by the collector deadband percent. You can only configure the collector deadband percent by enabling compression.
You must set Time Assigned by field to Source if you have unsolicited tags getting data from an OPC UA DA Collector.
