Hello,

I have troubles connecting with a CU320-2PN.

The led status are:

RDY is fixed red, COM is fixed red, OPT is off. Reading from manual this status is BIOS loaded and it seems that the booting procedure is not finish.

Regarding the CF card it seems all ok because i configured the CF card with an other CU320-2PN (same type) and all is working fine.

Someone has some suggestion to fix the CU? Is there some reset function for CU and not for CF card?

Regards,

Alessio

BUt you can ping and go online or not ?

If yes, can you check the fault list ?

Hi

What is your CU FW version?

If you can not connect to CU with starter, I suggest updating the Firmware using CF reader. Of course, first take a backup of the information on the CF.

SINAMICS S120 Firmware Version 4.8
