OPC XML DA Converter

OPC XML DA converter service that enables XML DA client to access OPC DA DCOM servers

The XML-DA Client to OPC-DA Server Gateway (XDAGW-SS) enables XML DA client applications to access OPC DA servers.
The XDAGW-SS Gateway offers a way to allow existing XML DA client applications access to the wide base of installed OPC DA servers.
The gateway is provided in version for IIS web services  and one for WCF. 
WCF offers more communications options but is useful only when both sides, client and server, are WCF based.

XDAGW-SS is compliance tested for XML-DA V1.0.1 and OPC-DA V2.05 and 3.0. If connected to an OPC-DA V3 server the OPC DA V3 features such as WriteVQT() are used, otherwise the server is accessed OPC-DA V2.05 compliant.

 

Configuration and Diagnostic Utility
The XDAGW-SS gateway configuration settings are defined in the AppSettings section of the web.config file.
The configuration utility displays the settings and changes can be made interactively instead of modifying the web.config file with a text editor.
The diagnostic features test the access to the OPC DA server and the XML DA gateway web service.
The .NET3 configuration is also in the web.config file and is modified with the WCF configuration utility.

 

Security
Web services don't provide a high level of security. Using HTTPS is the only option.
The gateway implements effective security measures. It can be configured to restrict the server access to an item subset. E.g. make some items read-only or allow only a subset of the items to be accessed.

The XDAGW-SS gateway is provided in a version for WCF that can be configured for secure communication.
In communication with WCF based XML DA servers, any WCF communication bindings can be used, including X.509 certificates
