Output Description

DONE

Data type: BOOL

The output DONE signals the completion of the process, triggered with the EN input. After finishing of the process or if an error occured, DONE is TRUE for at least one PLC cycle. The output DONE always has to be checked in conjunction with the output ERR. If ERR is TRUE, the output ERNO reflects the according error number. Otherwise the output parameter values are valid.

ERR (error)

Data type: BOOL

The output ERR signals any fault detected during the processing of the Function Block. This output always has to be checked in conjunction with the DONE output. If DONE is TRUE and ERR is TRUE, a processing fault was detected. The value of the ERNO output provides the according error number.

ERNO (error number)

Data type: WORD

The output ERNO provides an error number: Error Messages of the Function Block Libraries

NEW

Data type: BOOL

If output NEW=TRUE, a new timing value is available.

DUR (duration)

Data type: REAL

The output DUR is used for display the result of timing measurement. If the input EN_FREQ=FALSE, measured time is in µs.

FREQ (frequency)

Data type: REAL, unit: Hz

The output FREQ is used to display the result of time measurement. If the input EN_FREQ = TRUE, measured frequency is shown.

RPM (rotations per minute)

Data type: REAL, unit: rpm

The output RPM is used to display the result of timing measurement. If the input EN_FREQ = TRUE, measured speed of rotation is shown.
