   Special CoDeSys Variables


The following variables can be defined in CoDeSys to enable specific
functions on the panel. They all begin with the prefix "SPC_MB_". 

These variables must appear in a view in any way. For example in a 
rectangle element in the textdisplay-variable field. This element can 
be hidden. The best way is to insert these elements in the start view, 
mostly PLC_VISU.

A demo project showing the use of theses variables is available on
our website.


SPC_MB_Backlight
----------------

Description:

  With the variable "SPC_MB_Backlight", it is possible to contol the
  backlight of the embedded device.
  
  Since v00.21

CoDeSys definition:

  SPC_MB_Backlight:BOOL;

Variable value:

  0: the device behaves as normal, i.e. it switches the backlight off
     after a given timeout (see chapter Hardware).

  1: the backlight stays permanently on.


SPC_MB_Clock
-------------

Description:

  The panel doesn't have an internal clock. By defining the
  variable "SPC_MB_Clock", it is possible to set the time and date of
  the panel. This can be used for trend elements.
  
  Since v00.33

CoDeSys definition:

  SPC_MB_Clock:DT;

Variable value:

  The PLC application is responsible to periodically write the current time
  in this variable.
  
  Example: SPC_MB_Clock := SysRtcGetTime(dummy);
