This describes the physical location of the OPC Server software in relation to the SCADA Node. It is recommended to use either Local or Remote OPC Server choice. The In Process Server is a special type of Local OPC Server.
Local OPC Server Type is OPC Server software installed on the SCADA Node. This is the most common choice. It is recommended to use a Local OPC Server. You will be able to import tags from the Local OPC Server if the SCADA Node software is installed on the SCADA Node. If Local is chosen, then the "Browse OPC Sever" button will update the "List of OPC Servers" named at the bottom of the page with Local OPC Servers.
InProcess OPC Server Type is a special application of a Local OPC Server running in the same Process as the Client. There are many special requirements for an In Process Server (for example the Process must be registered, the DLL must be available to the Client, etc). It is recommended to use the Local OPC server if possible. Please refer to your OPC Server Guide for more information.
Remote OPC Server Type is an OPC Server software running on a computer that is NOT this SCADA node. To configure a Remote OPC server will need to specify the address of the computer running the OPC Server Software in the Field labeled "Remote OPC Server IP Address/Node Name" and the TCP Port used by the OPC Server (if any).
If Remote is chosen, then the data fields in PINK are used to connect with the Remote OPC server.
If Remote is chosen, then the "Browse OPC Sever" button will update the "List of OPC Servers" named at the bottom of the page with Servers from the Remote Computer described in Remote OPC Server IP Address/Node Name.
The WebAccess OPC Service must be installed on the remote computer in order to import tags from the Remote OPC Server using OPCTool.exe.
