Firmware update of the IO-Link device
 | Firmware update only possible with EtherCAT IO-Link master products The firmware update of the IO-Link device is only possible with the EP6224-xxxx, EP6228-xxxx and EL6224. A firmware update is not possible with the KL6224. |
An update of the box firmware is currently supported via the EP622x-xxxx IO-Link master box and the TwinCAT System Manager from version 2.11 R3 build 2248 or TwinCAT 3.1 build 4018.
The firmware update is performed directly via the IO-Link interface. To this end the box must be connected to the EP622x-xxxx and in Operational state. The update is started in the Advanced dialog of the corresponding IO-Link port (see the two figures below).
- Select the EP622x-xxxx Box in the System Manager,
- in the IO-Link tab, right click on the appropriate port
- open the Settings tab,
- select the Advanced button
- Select IO-Link firmware files via the Download button (use the file extension *.efw).
The Firmware Update dialog is only displayed for supported Beckhoff IO-Link devices. Once the *.efw file has been checked, the firmware update starts automatically. This process must not be interrupted! After a successful update, the box is automatically restarted and therefore usually does not have to be de-energized. Device-specific settings (Appl. -Specific Tag, Settings) will not be lost.
The firmware version that is currently used can be obtained as follows (see the figure below):
- Select the EP622x-xxxx Box in the System Manager,
- In the IO-Link tab, right click on the appropriate port
- open the Parameter tab,
- select Index 0x017 (firmware version)
- click the Read button
- The firmware version is read out and displayed when IO-Link communication to the box is active.
