DD1000i firmware​

New features​

The following new features are included in this release:

  • Time synchronization using NTP.
    • Time can now be imported to both the Upstream and Downstream proxies from an external NTP server.
    • The system clocks of the Upstream and Downstream proxies can now be synchronized with each other, regardless of if time is imported using NTP or not.
  • Remote logging using TLS.
    • It is now possible to forward logs to a remote log server using TLS.

Improvements​

The following improvements are included in this release:

  • A major version upgrade of the underlying operating system has been made.
  • It is now possible to explicitly select which interface (ADMIN or DATA) that shall be used when forwarding logs.
  • A log event is now generated when TLS session establishment to the DD Manager fails.
  • Third party dependency upgrades.

Bug fixes​

The following bugs have been solved in this version:

  • Uploading an invalid configuration file no longer results in the DD Manager displaying a blank page.
  • The Time elapsed counter displayed in the firmware upgrade pop-up window is now properly reset if a firmware upgrade fails.

Known issues​

The following issues are knowingly included in the release:

  • When configuring NTP import or remote logging using the DATA interface, it is not possible to use hostnames in the address fields, even if DNS has been configured for the DATA interface.
  • When remote logging is configured to use TLS, it is not possible to connect to a remote log server using IP address as the configured address, which in turn presents a certificate with its IP in the “Subject Alternative Name” field.
  • It is not possible to upgrade from a version prior to 4.2.0 to 4.5.0 on a device which has an invalid hostname configured. Doing so will cause the firmware upgrade to be aborted and rolled back to the previously installed version.
    • A valid hostname may contain alphanumeric characters (a-z and 0-9), dot (.) and dash (-). The hostname may be up to 64 characters in length.

OPC UA​

New features​

The following new features are included in this release:
