Version 1.0
Modified 08-MAR-2026 11:05:32.00
Code rt_plc_macro_logic.h 
 Edge detector.


 Detecting on a leading edge of a pulse.

 At detecting Status is TRUE during one program cycle.
RtBody attributes pwr_sClass_edge
Boolean in in The supervised signal.
Can be inverted by means of the Attribute Editor to
detect the trailing edge of a pulse.
Boolean Status sts When the supervised signal makes the transition FALSE
-- > TRUE Status is set, until the next execution
cycle, when it is reset.
Boolean StatusOld StatusOld The value of the supervised signal at the last scan.
