Problem:
After starting RTDAS it gives a fatal error as shown in the below screenshot.
Issue analysis:
Reason -Another DAS for this site is already running.
Steps to check the issue:-
1. Please check if another PlantConnect DAS service is running on the same machine in 'services.msc'
2. If service with some ASCII/garbage character display, then disable this service.
3. Again start the PLS from startup.
