Existance of Sequense of Events recorder Node in System 800xA
Is there a system with Sequense of Events recorder name and application in system 800xA?
what is the solution to achieve to the simsilar application and features in a specific Node?
As far as I know, SOE require special IO modules and special configuration in PLC (in AC 800M it is called ExternalTimestamp).
When correctly configured, alarms and events from such PLC & IO will have true timestamps (interrupt based in IO module rather than scan based in PLC).
The A&E will propagate to the HMI's collection and presentation services (Event Collector, Alarm Manager and Event Storage) like any other A&E. Event Historians, eg an IM running an OPC message log will not make any difference for SOE based A&E.
So, 800xA does not have any dedicated SOE recording mechanism. SOE gives high quality timestamps in the IO/PLC, but after that there are no differences upwards in the HMI.
Of course, you can name that message log "SOE logger" but that won't change anything. The difference with SOE is as said in the way A&E is timestamped at low level.
