| OPC XML-Data Access 1.00 uses HTTP protocol
and XML data encoding for communication between client and server. OPC DAXML 1.01, Server
implements the server role of OPC XML-Data Access 1.00 specification.
OPC DAXML 1.01, Server has proven it's capabilities in many prestigious projects. OPC DAXML 1.01, Server
provides following features:
- OPC DAXML 1.01, Server was certified by the OPC Foundation®
and allows a fast and seamless integration and reliable operation
- OPC DAXML 1.01, 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 DAXML 1.01, 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 DAXML 1.01, Server doesn't require any separate data point configuration. The
protocol stack allows direct access to data points configured at
subordinate protocol stacks
- OPC DAXML 1.01, 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 DAXML 1.01, Server also supports local time tagging of data points if the time
tag is not provided by the source of information
