OPC DA 3.0, Server

see also protocol(s)

 

OPC DA 3.0, Server is a powerful and reliable protocol stack. OPC DA 3.0, Server has proven it's capabilities in many prestigious projects. OPC DA 3.0, Server provides following features:

  • OPC DA 3.0, 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 3.0, 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 3.0, 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 3.0, 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 3.0, 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 3.0, 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 3.0, Server also supports local time tagging of data points if the time tag is not provided by the source of information
