Communication protocol 99
The StatusResponse service is used by the MN to query the
current status of CNs that are not communicating isochronously. It
is used for error signaling in runtime. If an error occurs, the EN
(Error New) flag in the PRes frame is toggled. This notifies the MN
that an error has occurred, and the MN polls the CN for a
StatusResponse that includes error information. A list of active and
historical error events can be read using SDO from object 0x1003.
