OPC DA Exchange Server

 

The OPC DA Exchange Server aggregates items from multiple OPC DA servers into the Exchange Server and exchanges data between these servers.
The Exchange server can be accessed as an

  • OPC DA V2/V3 server
  • XML DA web service

and is OPC compliance tested for OPC-DA V2.05 and OPC-DA V3.0.XML-DA V1.0.1.

The XML DA Exchange server is provided in version for:

  • ASP.NET2 web service
  • .NET3 (WCF) service

The .NET3 version can be configured to use different communication bindings:

  • basicHTTP for compatibility with ASP.NET2 web services
  • TCP or Named Pipe transport for high performance communication with .NET3 clients
  • Secure communication ( e.g. with X.509 certificates) with .NET3 clients
OPC Foundation Self-Tested for Compliance logo indicates that these products have been tested by the manufacturer to be compliant with the following OPC Specifications: Data Access 2.00, Data Access 2.05a, Data Access 3.00, XML-Data Access 1.00. Additional information about compliance testing, logo program and a summary of test results for OPC Exchange Server Version 1.0 can be found at www.opcfoundation.org.

 

 

 

The Exchange Server is:
  • a data aggregator
  • a server-to-server data exchange handler
  • an OPC DA to XML DA gateway

 

The Exchange Server handles any number of OPC DA child servers and any number of items. Configured items are mirrored in the Exchange server and can be read and written by the clients connected to the Exchange server.

Any number of child server items can be linked to one or multiple items in other child servers. Item value changes are written to all linked items.

The Exchange Server can be accessed as an OPC DA or XML DA server. Remote access using XML DA eliminates most DCOM issues.

The configuration application is extremely easy to use and also handles testing and maintenance tasks.
