800xA system status notification icon is not reliable.
I'm sure most of people must have noticed it. The icon does not always represent true status of 800xA system. If system is running it must be green but many times it can show up as Red.
Although everything else work fine, it can be confusing specially for people not so much familiar with 800xA.
As you know purpose of the 800xA system status notification icon is to show the 800xA service state from the perspective of the local node it is viewed from.
It can also be used to launch the Configuration Wizard and AfwServiceConnectionViewer.
Unfortunately states RED and RED with Padlock icon status may be shown even if the system is healthy.
The icon is driven by a regular ABB System Notification Icon windows service in 5.x ; Restarting it may recover the icon.
Hope this helps you
I'm sorry, but I have to agree 110% with your observations.
I would not for the world let my car's oil pressure light behave like this.
I recommend submitting a support case with your regional ABB support center. There exist even more powerful ways to file a complaint with ABB. If you like, please go ahead and use them.
