Introduction

This guide 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.

 

WARNING: Firmware updates should only be performed when the equipment being controlled by the OCS is in a safe, non-operational state. Communication or hardware failures during the firmware update process can cause the controller to behave erratically resulting in injury or equipment damage. Make sure the functions of the equipment work properly after a firmware update before returning the device to an operational mode.

Options for Updating Firmware

WARNING: 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.

 

Method A: Removable Media Method

The controller firmware is updated by a bootloader, using a microSD card or USB Flash drive (not through the Cscape Firmware Update Wizard).

 

To update or change firmware:

  1. Download desired Firmware set from the Horner APG website. (Verify CsCAN or CANopen communications.)

  2. Save Firmware files to microSD card or USB, these are the removable media devices.

  3. Update the firmware through the controller’s Firmware Update function

 

NOTE: Files from the Horner website come as a .ZIP file which need to be unzipped and placed in the root of the drive for them to function properly.

 

 

Method B: RS232 Serial Connection

Serial firmware updates are done from Cscape software to the controller’s primary serial port, MJ1 in most cases.
