7.5 Dynamic menu branchingBy means of this function, so-called tree-structured architectures can be created without costly PLC programming.• Display of the elements behind an arrow.• Selection with the cursor keys left " " and right " ".• Jump by operating the key " "• Display changes in the next selection text.• Then the last branch receives execution command.• With , the user always goes back one step, provided that bit 14 of the static control word is set.• The devices support up to 8 branching levels.According to DIN EN 60447, an operation sequence should run in three stages (selection of the device, selection ofthe assigned command, execution).The following graphic illustrates a procedure:Menu structure→Hall A(Text 10)→Hall B →Hall C(Text 200)Hall A→Pump →Motor →Valve(Text 300)Hall B→Pump →Motor →Valve(Text 400)Hall C→Pump →Motor →Valve(Text 210)Hall A Pump→On→Off(Text 220)Hall A Motor→On→Off(Text 230)Hall A Valve→On→Off(Text 232)Hall AValve On(Text 234)Hall AValve OffPicture: Menu branchingStarting from a basic text, in this case Text 10, the user selects the location of a device (Hall A). In the next step thedevice (valve) and then the command "Hall A valve open" whereby the result is reported.Process display and control/ Device Manual/ Issue: 07.01137E
