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.
