SOE Time Stamp in Controller
Hello,
Is it possible to read/know the SOE time stamp in controller?
My customer wants to know/see only the first-up alarm of SOEs on the graphic display.
Is there any way to display the above from SOEs.
Thanks in advance..

AFAICT, with AC 800M when using an SOE capable IO module the ExternalTimestamp feature can be enabled on the SimpleEventDetector or AlarmCond block. The IO address must be specified.
The alarm or event will then be issued based on the high precision SOE timestamp rather than the execution time of the code/task.
As far as I can tell, only alarm and event lists benefit from SOE, and not really visually.
Graphic Displays cannot interact with OPC AE information, only OPC DA.
