IDevice.GetSpecificDeviceErrorAsync (METH)¶

METHOD GetSpecificDeviceErrorAsync : PROC_STATE

Returns the fieldbus specific device error.

Note

This is an asynchronous method. For easier handling use function block GetSpecificDeviceError.

Note

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

InOut:

Scope	Name	Type	Comment
Return	`GetSpecificDeviceErrorAsync`	PROC_STATE
Input	`eCmd`	PROC_CMD
	`pData`	`CAA.PVOID`	Pointer to memory
	`szSize`	`CAA.SIZE`	Size of memory in bytes where pData is pointing to
Output	`szCount`	`CAA.SIZE`	Number of Bytes written to pData
