Historian OPC HDA Server License

A valid license is required for Historian OPC HDA Server. If you do not have a valid license, Historian OPC HDA Server cannot connect to the Historian.

Whenever Historian OPC HDA Server attempts to connect to the Proficy Historian, Historian Server verifies the Historian OPC HDA Server license.

Note: Historian OPC HDA Server does not consume a "Client Access License (CAL)" when Historian OPC HDA Server connects to the Historian.

If the Historian OPC HDA Server license is available, then the Historian OPC HDA Server can connect and read the raw data from the Historian. A message is logged into the Historian OPC HDA Server trace log file. By default, you can view the log file (that is, .html file) in C:\Proficy Historian Data\LogFiles. For example:

4/6/2009 4:32:05 PM HDA Client is connecting

4/6/2009 4:32:06 PM Connected to Historian server : [3.212.219.88]

4/6/2009 4:32:06 PM HDA Client Connected

4/6/2009 4:32:11 PM HDA Address Space Created

If the Historian OPC HDA Server license is not available, then the Historian OPC HDA Server cannot connect to Historian. A message is logged into the Historian OPC HDA Server trace log file. By default, you can view the log file (that is, .html file) in C:\Historian Data\LogFiles. For example:
