Output Description

DONE

Data_Type	Default_Value	Range	Unit
BOOL	-	-	-

DONE indicates the processing state of the function block. After completion or abortion of processing due to an error, DONE is set to TRUE for one cycle. This output always has to be considered together with output ERR. If ERR is TRUE, an error occurred. In this case, the error number can be read at output ERNO.

ERR (error)

Data_Type	Default_Value	Range	Unit
BOOL	-	-	-

ERR indicates whether an error occurred during the processing of the function block. This output always has to be considered together with output DONE. If DONE is TRUE and ERR is TRUE, an error occurred. In this case, the error number can be read at output ERNO.

ERNO (error \ number)

Data_Type	Default_Value	Range	Unit
WORD	-	-	-

ERNO provides an error identifier if an invalid value has been applied to an input or if an error occurred during job processing. ERNO has to be considered together with the outputs DONE and ERR. The value output at ERNO is only valid if DONE is TRUE and ERR is TRUE Error Messages of the Function Block Libraries.

RDY_REF (ready reference)

Data_Type	Default_Value	Range	Unit
BOOL	-	-	-

RDY_REF displays the ready message of the reference point approach.

RDY_TOUCH (ready message touch trigger)

Data_Type	Default_Value	Range	Unit
BOOL	-	-	-

RDY_TOUCH displays the ready message of the touch trigger measurement.

MAX_LIM (maximum \ limit)

Data_Type	Default_Value	Range	Unit
BOOL	-	-	-

In the infinite counter operating mode (endless mode), MAX_LIM indicates whether the actual counter value is higher than the value set at input LIM_MAX.

In the limiting counter operating mode (limit mode), output MAX_LIM is FALSE.

MIN_LIM (minimum \ limit)

Data_Type	Default_Value	Range	Unit
BOOL	-	-	-

In the infinite counter operating mode (endless mode), output MIN_LIM indicates whether the actual counter value is lower than the value set at input LIM_MIN.

In the limiting counter operating mode (limit mode), output MIN_LIM is FALSE.

CNT_ACT (counter actual)

Data_Type	Default_Value	Range	Unit
DWORD	-	-	-

CNT_ACT displays the actual counter value of the count-up counter.

CNT_TOUCH (counter touch trigger)

Data_Type	Default_Value	Range	Unit
DWORD	-	-	-

Output CNT_TOUCH displays the result of the touch trigger measurement, i.e. the actual counter value at the moment of the occurrence of the rising edge at input C2 after initiation of a touch trigger measurement by a rising edge at input EN_TOUCH.
