Siwarex U (7MH4950-1AA01) problems

Hi!

I'm having problems with Siwarex U1 weigher, 7MH4950-1AA01.

After the power off of the PLC rack, Siwarex started blinking SF light, and from module information I get the message parameters missing.

From programme, the FB gives following error code in FB_Err_c, see attachement. 

Second problem is that I can't connect with Siwatool U 2 to the weigher. Doesn't give any kind of error code. When I push online-button, it opens the connection screen but never gives any kind of error message or anything. COM-led will start blinking when I try to connect.

So only way I can insert any parameters is with HMI where I've programmed faceplate for weigher. Still not working as it should. Something is missing.

Can anyone give any advice?

Best regards,

Matilda
