Hi,

I'm trying to simulate Unified PC and keep getting this license error. Do I really need a license for simulating or is related to something else?

Hi K_Ohjus,

It is normal behavior. The system believes that the RT is actually running and asks for a license.This warning can be ignored.

However, if you are going to run that Runtime project on a PC later on, the PC must have the corresponding license.

Thanks.

Problem is that my project wont start after that message. Good to know that it is something else than license issue.

Reviewing information, it seems that an RT Unified license is required to simulate an RT PC.

Please see page 29 of the 'Installation Notes' pdf from the following link:

Delivery Release SIMATIC WinCC Unified V17 ES & RT

However, I think that if instead of an RT PC, you simulated a Unified Comfort Panel, this would not happen, as long as the Unified PC RT installation package is not installed.

It works now, it does not need license. (Simulation or RT)  only popup appears.

I do not know what was wrong, it just started working. I did not do anything just multiple retries.
