Password on any mode selection on scada
Respecting all the Valuable suggestions you have provided for my all queries everytime, I am having one more to ask !!
This may be easy, but I am not finding the Exact solution.
Compact HMI: v5.1
I am aware How to restrict any Faceplate or any Button,by using Security Aspect.
But all I want to know is How to put a PASSWORD,on the same(any faceplate/or any Mode_selection_option on any Tank mode)
Thanks in advance !!
It depends how secure you want it. The "most" secure mode ( and lets be honest, passwords in a control room are shared between operators so really arent that secure anyway) is to use Windows Logover and / or Double Authentication. The double authentication means somebody else has to authenticate an action or change and is probably the way that you "should" do it.
Or you could just store a password in a Controller Variable or General Properties aspect and compare that with a text entry field on the faceplate.
