OPC Classic

note

Note: OPC Classic is not supported in Docker.

This page describes the OPC Classic client connection of the OPC client in the OPC Router. It is part of the OPC Classic specification, specifically OPC DA (Data Access), and is used to read or write current values from classic OPC servers.

Classification​

  • Specification: OPC Classic
  • Standard Used: OPC DA (Data Access)
  • Typical Use: Connecting existing classic OPC servers in Windows environments

If the OPC server is running on another computer in the network, a correct DCOM configuration is required for OPC Classic.

Setup Procedure​

To connect to an OPC DA server, proceed as follows:

  1. Open the corresponding plug-in by clicking "Shopfloor" -> "OPC-Classic" in the "Plug-ins" menu.
  2. Click the plus button in the table header or double-click an existing entry.
  3. Make the necessary settings (see section “Properties of OPC Classic Connections”).
  4. Confirm with “OK”.

The connection to the classic OPC DA server is then available for connection configuration in OPC Router.
