DT11BreakEnc

D = Device(anpos-camming-camming2)

T = Control functions

The DT11BreakEnc functions executes a check to see any problems on the movement of analog axes. The function puts the device in emergency state (or report the emergency via a flag), when in 1/10 of a second (fixed time) with the analog output higher than the value contained in the MinVout parameter, the axis does not cover at least the space set to the MinSpost parameter.

IMPLEMENTATION

DT11BreakEnc(Asse, MinVout, MinSpost, EmrgOn, AlmEnc)

Parameters:

IN/OUT	VARIABLE TYPE	EXAMPLE NAME	DIM
IN	ANPOS EANPOS CAMMING	Axis (INTDEVICE)	-	Device type to which you can apply the function
IN	SYSTEM	MinVout	L	Vout minimum value after which you enable the control (1/10 V)
IN	SYSTEM	MinSpost	L	Displacement value min to do in 1/10 of sec
IN	SYSTEM	EmrgOn	F	If the Flag is set to 1, in the event of an alarm, the function by an emergency command to device; if set to 0 the function simply set the alarm flag
OUT	SYSTEM/ GLOBAL	AlmEnc	F	Alarm flag. If setting to 1 when the function detect the alarm, (regardless of the value of the EmrgOn parameter).

Example

MinVout = 3			;(0.3 Volt minimum voltage that enable the control)
MinSpost = 10	        	;(10 units of minimum displacement measurement to be performed in 1/10 of sec)
EmrgOn = 0			;(Enables only the flag and not the emergency command directly to the device)
DT11BreakEnc(Axis, MinVout, MinSpost, EmrgOn, AlmEnc)
IF AlmEnc
     IF NOT Axis:st_emrg
            EMRG Axis
     ENDIF
ENDIF

Note

This function should be placed at a point of the application that runs on every round makes sense so that control is constant.
The AlmEnc flag is reset automatically when the emergency situation becomes invalid (voltage for the device that falls below the set value in the (MinVout) parameter.
