800xA HI - Confirmed write support

Hi!

I have added a SignalReal in my SIL application.

The value should be manoeuvrable from the 800xA Workstation.

The icon/faceplate is available in the HMI, but the access is denied to the object.

I don't know which aspect to change to enable the object.

I read in the manual that I should use the "Confirme write Support" aspect. But I don't understand what settings to change to enable the object.

I have the right permission since I am able to manoeuvre already existing objects of the same type.

Does anyone have any idea for the proper settings/solution?

Best regards Conny
