Special registers
Special registers let you control OS functions and retrieve status information.

Global variables which are assigned to permanent addresses (%VL)
 When the operating system is launched, special registers are initialized
using default values.
 Register numbers: 100,000 ... 999,999

By JetSym
 By browser (via HTTP server)
 From HMIs
 From the application program
 From other controllers
In the following program, two special registers are used. The first is the special
register for status LEDs, the second is the special register for digipot values.
In this task, the value is just copied from the special register for digipot values
to the special registers assigned to the status LEDs. If the application program
is running on the HMI and you turn the digipot, the value contained in the
digipot special register is displayed by the status LEDs.
Var
Digipot: Int At %VL 363000 ;
Status_LEDs: Int At %VL 362100 ;
End_Var ;
Task Main Autorun
Loop
Status_LEDs := Digipot;
