1.1 Installing OPC Core Components

OPC Core Components are required for OPC servers and OPC clients to run. If the server and the client are installed on different computers, this package must be installed on both computers. If the client or the server runs on a 64-bit version of the operating system and they are 64-bit applications, you need to install the corresponding version of OPC Core Components.

You can download OPC Core Components free of charge from opcfoundation.org.

  1. Move the mouse pointer to one of the desktop corners;
  2. Select Settings - Control Panel - Programs - Turn Windows Features on or off in the Windows sidebar;
  3. Select .Net Framework 3.5 in the tree. Clear the Activate Windows Communication Foundation checkboxes.
