Remote OPC Systems Service Access

The OPC Systems Service must be started to be accessed by a local or remote OPC client component or application.  Use the OPC Systems Service Control application to Start the Service.

If you are using a Firewall or Windows XP Service Pack 2 make sure to open up port 58724 for Configure OPC Systems.NET, OPC Trends and Alarms, OPC Systems Service, and any Visual Studio.NET application you have developed using the OPC Controls.NET, OPC Web Controls.NET, OPC Mobile.NET, OPC Alarm.NET, OPC Web Alarm.NET, OPC Trend.NET, or OPC Web Trend.NET components.  This port number is adjustable in the service and in all .NET dlls.
