Output Description

Function Block PUMP_INTERFACE

DONE

Data_Type	Default_Value	Range	Unit
BOOL	-	-	-

Output 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: BOOL

Output ERR indicates whether an error occurred during data reception. If 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	0	³ 0	-

Output provides an error identifier if an invalid value was applied to an input. ERNO always has to be considered together with the output ERR. The value output at ERNO is only valid if ERR is TRUE (see, error messages): Error Messages of the Function Block Libraries

PUMP_START (pump start)

Data type: BOOL

On command to the pump.

PUMP_REF (pump reference)

Data type: INT

Speed reference to the pump in terms of RPM.

PUMP_REF_FB (pump reference field bus)

Data type: INT

Field bus speed reference to the pump in the range of -20000 to 20000.

PUMP_RUNTIME (pump runtime )

Data type: TIME

Runtime value for the pump.

PUMP_FAULT (pump fault)

Data type: BOOL

TRUE when the pump encountered a fault. This fault can be because of drive tripped, pump protection fault, or due to PUMP_ON=FALSE when the boost control or the level control is running.
