+====== IR10EdgTmInp ======
+**I = **//Input//
+**R = **//Reading functions//
+The IR10EdgTmInp function __detects the rising edge of a digital input__.
+In particular:
+  *the function sets the flag on the rising edge whenever the digital input transitions from the off state (value 0) at the active state (value 1);
+  *the function sets the flag on the falling edge whenever the digital input transitions from the active state (value 1) at the off state (value 0);
+  *flags that pertain to both sides are reset automatically by the function after a settable time (timeReset).
+===== IMPLEMENTATION =====
+**IR10EdgTmInp (Input, FronteUp, FronteDw, timeReset)**
+Parameters:
+^IN/OUT^VARIABLE TYPE^EXAMPLE NAME^DIM^^
+|  IN  |  INPUT / SYSTEM  |  Input  |  F  |Digital input or variable you want to "capture" the front|
+|  OUT  |  GLOBAL  |  FronteUp  |  F  |Flag on the rising edge|
+|  OUT  |  GLOBAL  |  FronteDn  |  F  |Flag on the falling edge|
+|  IN  |  CONST SYSTEM  |  timeReset  |  L  |Waiting time before reset capture flag fronts (msec)|
+=== Example ===
+In the example the "ofUscita" output is set on the rising edge of the input "Input" and it's reset on the falling edge of the same entrance.
+**IR10EdgTmInp (Input, FronteUp, FronteDw, timeReset)**
+<code QCL>
+IF FronteUp
+        SETOUT ofUscita
+ENDIF
+IF FronteDw
+        RESOUT ofUscita
+ENDIF
+</code>
+=== Note ===
+  * In order to be effective, the function should be placed at a point of the application that runs on every logical round.
+  * Front capture flags remain in the State for the 'timeReset' time, then the function automatically resets them.
