Reconnecting to the OPC HDA Server

About this task

The OPC Classic HDA collector supports auto reconnect to the OPC Classic HDA collector. If the connectivity between the OPC Classic HDA server and the collector is down due to network connectivity issues, the collector will auto reconnect to the server when the server is back and running. The collector polls for the server connection for a set timer of every 5 seconds.

To enable Auto Reconnect to the OPC Classic HDA server:

Procedure

  1. From the Start menu, select Run and type Regedit. Then, select OK. The Registry Editor appears.
  2. Open the key folder: HKEY_LOCAL_MACHINE\SOFTWARE\GE Digital\iHistorian\Services\ OPCHDACollector.
  3. Locate the Key created with the ProgID of the OPC Classic HDA server, which you entered while installing the OPC Classic HDA collector.
  4. Create a new DWORD labelled, EnableOPCHDAReconnect.
  5. Enter the decimal value 1.
    Note: If this registry is not created and set to a value of 1, then the Auto Reconnect functionality will not be enabled.
