| Exception Type | Condition |
|---|---|
| OpcServerConnectException | The client was unable to connect to the specified server. Check inner exceptions for more details on the reason for the inability to connect. |
This value denotes when the OpcConnection is actually connected to the server. In most cases, you only desire to connect to the OPC server when the component is in the run mode, not during design time. However, if this funtionality is required, set the ConnectionScheme to the appropriate value. Use ManualConnect when you require complete control of when the OPC Server is connected or not.
