GetDeviceError (FB)¶

FUNCTION_BLOCK GetDeviceError EXTENDS CBM.ETrigA

If IDevice.GetDeviceState returns DEVICE_STATE.ERROR this function block returns the associated device error code. The error codes are fieldbus specific and will be defined by the associated communication stack.

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
Output	`eError`	ERROR	operation error code
Output	`einDeviceError`	ERROR_INFO	device error code
