OPC DA 2.05 Server
 This protocol stack can be used with following products
This protocol stack was used in following projects
| OPC DA 2.05 Server is a powerful and reliable protocol stack.
OPC DA 2.05 Server has proven it's capabilities in many prestigious projects. OPC DA 2.05 Server
provides following features:
- OPC DA 2.05 Server was certified by the OPC Foundation®
and allows a fast and seamless integration and reliable operation
- as an integral part of the certification procedure OPC DA 2.05 Server was
tested in a workshop carried out by the OPC Foundation®
with OPC Clients of many other vendors such as ABB® 800xA System, Siemens® Simatic WinCC V6.00, Wonderware®
Industrial Application Server/FSGateway, ICONICS®
GraphWorX32 etc.
- OPC DA 2.05 Server supports either local communication (client und
server running on the same machine) and distributed communication over
LAN (client and server running on different machines)
- OPC DA 2.05 Server supports several simultaneous, independent and fully
operational connections to different OPC clients. The maximum number of
connections is only limited by the system resources
- OPC DA 2.05 Server doesn't require any separate data point configuration. The
protocol stack allows direct access to data points configured at
subordinate protocol stacks
- OPC DA 2.05 Server supports transmission of quality and time tag
directly from the information source i.e. if the data points are
gathered by protocol stacks like IEC 60870-5-101, Master, DNP V3.00, Master etc., the
original quality information and time tag (if available) is preserved
and transmitted to the OPC client
- OPC DA 2.05 Server also supports local time tagging of data points if the time
tag is not provided by the source of information
