10.9.9 Monitor functions
This chapter provides a description on how an HMI can be used to display and
change variables independent of the application program.
For the monitor functions, the following requirements have to be met:
 An HMI with numeric keypad must be connected to the controller.
 The monitor functions must not be blocked in the configuration registers.

The STX instruction UserInput() for inputting numerical values must not
be active.
The monitor function can only access controller variables which are assigned
to permanent addresses.

Registers (%VL)
 Flags (%MX)
 Inputs (%IX)
 Outputs (%QX)
In multi-display mode, the following must be taken into account:
 The monitor function is only displayed on the HMI on which you have
activated it by pressing the key [R] or the key [I/O] .

The controller is not able to tell apart on which HMI subsequent keystrokes
are carried out.
