How can remote OPC DA servers be accessed?
The DCOM, Firewall and Windows security settings for remote OPC server access are the main cause of troubles getting Remote OPC server access to work. Advosol offers the free OpcSecurityAnalyzer utility as tool to find the proper configuration settings. Tunnelling and Bridging solutions eliminate teh remote DCOM communication. Tunnelling solutions use a proprietary TCP communication and require a matching module on both sides. The Advosol bridging products use the OPC specified XML-DA communication. With .NET3 (WCF) the coommunication can be configured to achieve the same performance as a tunnelling approach. An XML-DA gateway is installed at the OPC DA server location. Through the gateway, XML-DA clients located anywhere can access the OPC DA server. The client applications can be implemented as XML-DA clients or OPC DA clients can use the Advosol OPC DA to XML-DA gateway.
