Programming in the programming language JetSym STX
JetViewSoft lets you create visualization applications for use on the following
platforms:
 PC systems

HMIs for industrial applications
 HMIs for mobile applications
JetSym STX lets you access visualization objects and control their
representation on the HMI. The programming language JetSym STX lets you
program the HMI as if it were a controller. The compiled programs can be
processed in the HMI without the need for an external controller. This is made
possible by the STX interpreter and the graphical runtime environment JVER
(JetView Embedded Runtime). Both form an integral part of the HMI's
operating system.
The program listed below switches the status LEDs on the left and the right of
the display ON and OFF. This example shows how JetSym STX can be used.
Task Mini Example AutoRun
Var
// Bit-coded mapping of status LEDs
LEDs: Int At %VL 362100 ;
End_Var ;
Loop
If LEDs > 0 Then
// All LEDs OFF
LEDs := 0 ;
Else
LEDs := 0xFFFFFFFF ;
End_If ;
Delay (
T#500ms );
End_Loop ;
End_Task ;
When you load the compiled program to the HMI, JetSym creates in the
directory \App a folder and names it after the project. JetSym stores the
application program to this folder. The file name of the application program
comprises of the project name and the extension *.es3 . Path and file names
are always converted into lower case letters.
The file
start.ini is automatically created on program download. It defines
which application program is to be loaded.
