-OpcUa Plugin:
-=============
-
-This plugin implements the dissection of the OpcUa Binary Protocol.
-Author: Gerhard Gappmeier
- ascolab GmbH
- http://www.ascolab.com
-
-Overview:
-=========
-
-OpcUa (OPC Unified Architecture) is a vendor and platform independent
-protocol for automation technology. It is the successor of the
-COM/DCOM based specifications OPC DA, OPC Alarm & Events, OPC HDA, etc.
-It unifies all this technologies into a single protocol.
-
-The specification describes abstract services that are independent
-of the underlying protocol. For now there exist protocol mappings
-to a Binary TCP based protocol and a SOAP based Webservice.
-Also a hybrid version will be available where the Binary messages are transported
-by a single webservice command called "Invoke".
-
-More information about the technology you can find on
-http://www.ascolab.com/index.php?file=ua&lang=en.
-
-Protocol Mappings:
-==================
-
-Binary (TCP): The fastest and most flexible version (small footprint, no XML and SOAP necessary)
- can easily be tunneled (SSH, IPSEC, etc.), redirected, ...
-SOAP version: Easy to implement with verious tools like .Net, JAVA, gSOAP, etc.
- Better to communicate through firewalls via HTTP.
-SOAP with Binary Attchment: Combines the advantages of both.
- The messages are encoded as Binary, and transported via SOAP as binary
- attachment.
-
-The OPC Foundation offers a free Opc Ua stack implementation in ANSI C
-for all members. This stack implements the binary protocol as well
-as the SOAP version. It's easily portable to different kinds of operating
-systems from embedded devices to servers.
-This makes it easy to implement Opc Ua applications based on this stack
-and it is expected that the binary protocol will be the most used
-protocol.
-Nevertheless it's free to everbody to implement an own stack according
-to the specification. An own implementation of the SOAP version
-should be easy with the various SOAP toolkits.
-
-For more information see http://www.opcfoundation.org
-
-Known limitations:
-==================
-
-* In this version the security layer contains only dummy data.
- The plugin decodes the transport layer, skips the security dummy data
- and decodes the application layer.
- Security implementation will follow when it has been implemented in the
- Opc Ua stack.
