Inputs

Type

Comment

HSC_REF_IN

Reference to the HSC.

Must not be changed during block execution.

Execute

BOOL

On rising edge, starts the function block execution.

On falling edge, resets the outputs of the function block when its execution terminates.

This table describes the output variables:

Outputs	Type	Comment
HSC_REF_OUT	HSC_REF	Reference to the HSC.
Done	BOOL	TRUE = indicates that HSCDiag is valid. Function block execution is finished.
Busy	BOOL	TRUE = indicates that the function block execution is in progress.
Error	BOOL	TRUE = indicates that an error was detected. Function block execution is finished.
ErrID	HSC_ERR_TYPE	When Error is TRUE: type of the detected error.
HSCDiag	DWORD	When Done is TRUE, the diagnostic value is output to this pin in the function block. When Bit 7 of the DWORD = TRUE, a configuration error is detected. The Bits 0...6 and 8...15 are not used.

NOTE: For more information about Done, Busy and Execution pins, refer to General Information on Function Block Management.
