Firmware manager damaged two Ethercat and Profinet B40 Bricks


I tried to upgrade the firmware on my Ethercat and Profinet bricks. Each attempt failed and damaged the brick.

I have a couple of ECT and PIR B40 bricks and wanted to upgrade them with the latest firmware. The firmware manager found both bricks and started the upgrade but failed after some time. After the failed upgrade they do not work anymore. Quick test fails: usually with the power supply the LEDs start blinking. I cannot re-upgrade them, because the firmware manager does not recognize the bricks. What is the reason and how can I repair the bricks?


Hi @AndyK,

I would recommend opening a support case for this issue at

Please include the serial numbers of the damaged devices and the link to the firmware that you used.
