Firmware Release Note Changelog

CLICK HERE to download our OCS Firmware Update Manual which details how to update or change firmware on the Horner OCS Controllers. Updating firmware to the newest version adds new benefits to the controller. Also, changing firmware is necessary when changing communications between CsCAN and CANopen.

Remember:  Updating firmware will clear the application program, screens, configurations, and register data.

If required, make sure to backup program and register data before updating firmware. The controller’s User Manual has instructions for doing backups.
