Output Description

DONE

Data_Type	Default_Value	Range	Unit
BOOL	-	-	-

Output DONE indicates that clock setting is completed. The output always has to be considered together with output ERR.

The following applies:

• DONE = TRUE and ERR = FALSE:

  Clock setting is completed.

• DONE = TRUE and ERR = TRUE:

  An error occurred during clock setting. The error number is indicated at output ERNO.

ERR

Data_Type	Default_Value	Range	Unit
BOOL	-	-	-

Output ERR indicates whether an error occurred during clock setting. This output always has to be considered together with output DONE. If DONE = TRUE and ERR = TRUE, an error occurred during Function Block processing. In this case, the error number can be read at output ERNO.

ERNO

Data_Type	Default_Value	Range	Unit
WORD	-	-	-

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