How can I display my own logo instead of ABB logo at the upper left corner of Digivis Display
Don't you like ABB logo with hint indication there ;)
In digivis only display area is configurable, The message line frame is fixed and can not be customised. Moreover it is not only logo, also displays indication if there is hint message by small yellow color rectangular box. You can configure your own logo in display area on each graphic page as replied by csanchez.
