Function keys
The HMI JVM-407B has four function keys: F1 to F4. These function keys are
user-programmable.
In register 361000 of the JVM-407B, there is a bit-coded mapping of the
function keys which can be used for programming.
The sample program has been tested for compliance with the following
software versions:
 JetSym version 5.1
 HMI JVM-407B, OS version 4.01
For more information on programming by STX, please turn to the online help
in JetSym.
Prerequisites:
So that the status LEDs are not also controlled via the JVM-407B inputs, the
inputs IN1 to IN10 should not be set whilst running the sample program.
In the following sample program, the function keys are continuously retrieved
in one task. Pressing one or more keys controls the status LEDs assigned in
the program.
Var
F_Button_Register: Int At %VL 361000 ;
Status_Led_1: Bit At %XL 362100.0 ;
Status_Led_2: Bit At %XL 362100.1 ;
Status_Led_3: Bit At %XL 362100.2 ;
Status_Led_4: Bit At %XL 362100.3 ;
End_Var ;
Task Main Autorun
F_Button_Register := 0 ;
Loop
If F_Button_Register. 0 Then
Status_Led_1 := True ;
Else Status_Led_1 := False ;
End_If ;
If F_Button_Register. 1 Then
Status_Led_2 := True ;
Else Status_Led_2 := False ;
End_If ;
If F_Button_Register. 2 Then
Status_Led_3 := True ;
Else Status_Led_3 := False ;
End_If ;
