Keep in mind that the timestamps Ignition gets from an OPC UA server, or generates in its own drivers, is almost always the timestamp of the _ **poll** _, when the change was detected by OPC, not the actual timestamp when the signal changed in the real device. This means the ordering will be pseudo-random for signals that changed close in time, less than the poll interval.

If you really need sequence of events, you **must** timestamp **precisely** in the PLC and then buffer transfer to Ignition.
