GetSpecificDeviceError (FB)¶

FUNCTION_BLOCK GetSpecificDeviceError EXTENDS CBM.ETrigA

This function block delivers the fieldbus specific device error.

Bemerkung

The interpretation of pData is fieldbus dependent and will be specified by the associated fieldbus driver.

Bemerkung

This feature may not be supported by all fieldbus drivers. eError will return ERROR.NOT_SUPPORTED if not supported.

InOut:

Scope	Name	Type	Comment	Inherited from
Input	`xExecute`	`BOOL`	Rising edge: Action starts Falling edge: Resets outputs If a falling edge occurs before the function block has completed its action, the outputs operate in the usual manner and are only reset if either the action is completed or in the event of an error. In this case, the corresponding output values (`xDone`, `xError`, `iError`) are present at the outputs for exactly one cycle.	ETrigA
Input	`xAbort`	`BOOL`	`TRUE`: Action is stopped immediately and all outputs are reset to their initial values.	ETrigA
Output	`xDone`	`BOOL`	`TRUE`: Action successfully completed	ETrigA
	`xBusy`	`BOOL`	`TRUE`: Function block active	ETrigA
	`xError`	`BOOL`	`TRUE`: Error occurred, function block aborts action `FALSE`: No error	ETrigA
	`xAborted`	`BOOL`	`TRUE` : Action aborted by user	ETrigA
Input	`itfNode`	INode	device node
Input	`pData`	`CAA.PVOID`	Pointer to memory where specific device error information should be copied to.
Inout	`szSize`	`CAA.SIZE`	IN: Size of memory pData points to. Out: Size of data copied to pData
Output	`eError`	ERROR	operation error code
