Need to connect a remote OPC client to ClearSCADA bypassing DCOM configuration.
This can be achieved by installing the Data Access component of ClearSCADA on the remote machine hosting the OPC client. To install and configure the component follow the steps below:
1. Run the ClearSCADA Installer on the remote machine hosting the OPC client and select "Install ClearSCADA".
2. Select Custom installation and only install the Data Access component:
3. You should now see the Configure Connections program if you click on the Windows Start button. If the program cannot be located in Windows Start menu, the program can be run directly from: C:\Program Files (x86)\Schneider Electric\ClearSCADA\ClientConfig.exe (on 64-bit machines) or C:\Program Files\Schneider Electric\ClearSCADA\ClientConfig.exe (on 32-bit machines)
4. Run the Configure Connections program and create a connection to the ClearSCADA server by specifying the IP address (or server name) of the ClearSCADA server in the Node Name field of the Node A tab and select OK to apply the changes:
5. Your OPC Client should now see ClearSCADA OPC Server among its local OPC servers as below:
The OPC service name takes the format of the following based on the information defined within the Configure Connections program:
Serck.ScxV6OPC[OPC type].[System name].[Host address or IP address]
|The Data Access component uses TCP port 5481 (default) to communicate to ClearSCADA server and the server connects
back to the client on TCP ports 5500-5509. Make sure these ports are not being blocked on either machine hosting the OPC
client or ClearSCADA server. It is possible that your application might have different ports allocated for client-server communication.
