Hi everybody
I want the PLC know the current page of the HMI (Siemens MP277, programmed with winCCflexible 2008). I set, in coordination -> page number, the address DB1.dbw16
It's a 5 word object, and in the 2nd word I find the current page of the HMI.
But when I switch on the HMI, sometimes I find the last page before switching off.... it seems like it doesn't refresh...
Is there something else to set in winCC if I want to do this?
