Hello everyone,

I am a total new user of Wincc Unified and I am trying to simulate my 1200 Unified panel in my PC using the WinCC Unified web interface. But I keep getting the message "the validation of the parameter 'service' failed".

I am using the user configured in WinCC Unified configuration wizard, and I made sure that all Windows services required are activated.

Your help is highly appreciated.

Hello Ro14,

Thanks for your reply.

It turned out to be an update problem. It works fine now after using TIA16 Update 4.
