Firmware Update

Overview​

This page describes the WPS firmware update flow for supported devices. It does not replace product manuals or device-specific requirements.

Use the device-specific firmware update page when the device has additional requirements, such as a specific communication interface, Unit ID, firmware file extension, Ethernet delay setting, accessory update procedure, or restriction.

Device-specific example

For an example of how device-specific firmware update requirements are documented, see the CFW500 firmware update page.

The flow on this page explains the WPS firmware update procedure. Device pages add product-specific details, such as firmware source availability, required file extension, communication settings, limits, and restrictions.

Firmware update procedure​

Screenshot note

The screenshots in this procedure were captured from a CFW300 and are provided as visual reference only. The WPS wizard uses the same firmware update flow for supported devices. Because this documentation covers many devices with the same interaction pattern, the screenshots are not duplicated only to change the product name. Apply the requirements listed on the device-specific page before starting the update.

Firmware compatibility and operation

The firmware update will not be completed if the binary file is incompatible or corrupted. Before updating firmware, stop program execution and make sure the device is not operating or driving a motor.

Feature availability

The option to select a firmware version directly from WPS is not available for all supported devices. When this option is not available, use the firmware file selection option and confirm the required file extension in the product manual or in the device-specific documentation.

Before you begin​

The firmware update is started from the Online menu in WPS. The procedure does not require an existing WPS project or an existing resource in the workspace.

Before starting, make sure you have:

  • The firmware binary provided by the supplier or technical support.
  • The device connected to the computer.
  • The device powered on.
  • The communication settings required by the device or accessory being updated.
  • The setup information from the Technical Support Manual for Firmware Update via WPS, available from the WEG website.

Firmware update procedure​

1. Connect and power the device​

Connect the device to the computer and make sure the device is powered on.

You do not need to create or open a WPS project before starting the firmware update.

2. Configure communication in WPS​

In WPS, open the firmware download workflow:

From the Top Menu, go to Online > Firmware Download.

Firmware Download option in the Online menu

The communication configuration screen will be displayed.

In this screen, configure communication for the target device:

  1. Select the device from the device list.
  2. Select the physical layer.
  3. Adjust any additional communication settings required by the selected product, physical layer, or accessory.
  4. Click Test to verify communication between WPS and the device.

3. Continue after a successful communication test​

If WPS can communicate with the device, the Next button is enabled.

Click Next.

4. Choose the firmware source​

Select a firmware version available in WPS by using the firmware-version selector.

Disabled version selector

If the firmware-version selector is disabled, WPS may be outdated. Update WPS to access the latest firmware update features and corrections by opening Quick Start > Check for Updates and completing the update flow.

5. Review the firmware information and start recording​

After the firmware file or WPS firmware version is selected, WPS displays the firmware information below the selected source.

Click Finish to close the wizard and start recording the firmware.

6. Confirm the firmware update​

WPS displays a confirmation message.

Click OK to confirm.

7. Wait for the firmware recording process​

The firmware recording process starts.

Wait until the process is complete. WPS shows progress information in the Output window and in the status bar.

8. Complete the update and restore communication if required​

When the firmware recording process is complete, WPS displays a completion message in the Output window. Depending on the device, the device resets or displays an HMI message requesting a restart.

After the reset or restart, you may need to configure the communication parameters again before the device can communicate with WPS.
