Product Overview

The SIXNET UDR driver exchanges data between OPC clients and SIXNET RTUs using the Native SIDNET protocol. It supports both Serial and Ethernet connections, and also supports the IPM Linux-based RTU. The driver supports a unique pass through feature of the Sixnet protocol that allows you to configure an RTU while continuing to gather data. Kepware automatically optimizes data acquisition based on client demand, and data integrity is ensured with our extensive error handling.

  • Removed non-inclusive terms out of respect for users of our software.


  • Resolved an issue where the driver would not run if another application was already using the dependency files maintained by SIXNET. The driver will now search the server's application directory first for SIXNET files 'six32com.exe' and 'udrcom32.dll'. If they are not found locally, the driver will fall back to the system directory.


  • Reference to SIXNET files 'six32com.exe' and 'udrcom32.dll' was changed from windows\system32 to the application's root directory to ensure that the driver uses its own compatible version and not a version installed by other applications.


  • Fixed access violation when the driver dll is unloaded and reloaded.
