+====== DT21BreakEnc ======
+**D = **//Device(oopos-oopos2)//
+**T = **//Control functions//
+The __DT21BreakEnc function executes a check to see any problems on the On/Off axes movement__. The function commands a stop device (or report the emergency through the flag), when with the active forward or back output, the axis, in the time set in //TmCntrl// parameter, covered at least the space set to the //MinSpost parameter.//
+===== IMPLEMENTATION =====
+**DT21BreakEnc(Axis, MinSpost, TmCntrl**, **EmrgOn**, **AlmEnc)**
+Parameters:
+^IN/OUT^VARIABLE TYPE^EXAMPLE NAME^DIM^^
+|  IN  |  OOPOS OOPOS2\\ OOPOS3  |  Axis (INTDEVICE)  |  -  |Device type to which you can apply the function|
+|  IN  |  SYSTEM  |  MinSpost  |  L  |Minimum displacement value to do over time //TmCntrl// (UM)|
+|  IN  |  SYSTEM  |  TmCntrl  |  L  |Time to execute the minimum movement //MinSpost //(msec)|
+|  IN  |  SYSTEM  |  EmrgOn  |  F  |If the Flag is set to 1, if an alarm function, gives a stop command to the device; is set to 0 the function simply set the alarm flag|
+|  IN  |  SYSTEM/\\ GLOBAL  |  AlmEnc  |  F  |Alarm Flag. Set to 1 when the function detects the alarm, (regardless of the value of the //EmrgOn parameter//).|
+=== Example ===
+<code QCL>
+MinSpost = 10		;(10 units of measure of displacement)
+TmCntrl = 1000		;(1secTime in which to execute the MinSpost space)
+EmrgOn = 0		;(Enable only the flag and not the stop command directed to the device)
+DT21BreakEnc(Axis, MinSpost, TmCntrl, EmrgOn, AlmEnc)
+IF AlmEnc
+     IF NOT Axis:st_still
+            STOP Axis
+     ENDIF
+ENDIF
+</code>
+=== Note ===
+  * The AlmEnc flag is reset automatically when the emergency situation becomes invalid (stoped device).
