Resolution: If PLSCADA is running as a service you will not able to open another instance of the Runtime Project. The only instance that may is open will be displayed as running as host 0 instance. If an attempt is made to open another instance of the project, it will not run. All of the Citect32.exe processes will shutdown shortly after starting. Another symptom will be that you can see some meter values but not able to see circuit breaker status's or one line status's. If you are unsure as to whether or not SCADA is running as a service open the Windows Task Manager and note how many processes are running for Citect.exe. You can select to show Session ID in task manger to see under what session the citect32.exe are running under.
