Is there a known command to read out the device serial number “UN315640102…95+000000…” via command line?

Hi,

For Newer FW you can also use **/etc/config-tools/get\_typelabel\_value UII** to Print the UII Number of the Device.

Hi,

Is there a library that can read the serial number from CODESYS? I am guessing we could use the FuExecuteCommand fb to pass a command, but am looking to see if there is something already built.

Thank you,

Hi Mike,

I was exactly in the same situation as you and looking for a simple answer.  
It has started with customer’s enquiry to obtain serial number in CODESYS project.  
Unfortunately library “SysTarget”, even though equipped with function **SysTargetGetSerialNumber** , returns a MAC address instead of serial number.

One solution is to use library **WAGOAppConfigTool** :

And add a fb call in your program:

@WagoDamRud has described it further in this post: [SSH command from CoDeSys - CODESYS - WAGO Open Source Community](https://www.wago.community/t/ssh-command-from-codesys/1048/3).

Hope this helps! 🙂

Another way would be to use the Web Client SL with localhost communication and use the WDX Rest API. But this is more complicated then using the Config-Tool Script 😃

Hope they will add a Codesys Client Library for the WDX Component very soon!
