8.5.3 Function keys
Function keys
Function key assignment is defined during configuration. The configuration engineer can
assign function keys globally and locally.
Function keys with global function assignment
A globally assigned function key always triggers the same action on the HMI device or in
the PLC irrespective of the screen displayed. Such an action could be, for example,
the activation of a screen or the closure of an alarm window.
Function keys with local function assignment
A function key with local function assignment is screen-specific and is therefore only
effective within the active screen.
The function assigned locally to a function key can vary from screen to screen.
The function key of a screen can be assigned one function only, either a global or local one.
The local assignment function takes priority over the global setting.
The configuration engineer can assign function keys in such a way that you can operate
operating elements with function keys, for example, the alarm view, trend view, recipe view
or Status Force.
