Hi,

thank you very much. It fixed my problem with the colors.

But now I have a problem with my connection to the PLC's. I checked it and as soon as I made the update for the winCC the connection cannot be established anymore.

To ping the PLC's is no problem

Do you know maybe what the issue could be?

I'm using S7-1500 Channel OMS+

My PLC's are 1518F-4 with Firmware version v2.9

Siamtic Net 16 is installed

Split from WinCC color palette.

Hello roxas21

I know the reason it is all about the new security features of the enchrypted HMI connection.

you have to do exactly all steps of this FAQ (also if you have disabled the secure HMI conneciton in the PLC):

Because of the Upd 4 or newer you only can work with the new 2.9 FW together with importing the certificate  like in the FAQ described.
