Faulty Modicon Quantum CPU

[OsamaSalih]

Hi All

First  I want to thank you all for valuable support

I have this 140CPU43412A  and planned to upgrade it from Concept to Unity.

Looks like something went wrong and after downloading the intermediate OS it stopped

responding and the RUN led blinks 7 times (means that No exec loaded)

What could be done to fix this problem?

Hello,

You're not ready after loading the intermediate firmware. Next step is loading the Unity/EcoStruxure Control Expert firmware.

Please follow the steps as described in chapter 2 of the document:

Hey @OsamaSalih , did this reply solved your issue? If yes, please mark it as solved or let us know so we can provide you more support 😉

thank you @ I can not proceed to the next step because the PLC is not responsive to connection attemps, it is not detectable by the OS loader
