4.3.1.4 Emergency Object (EMCY)

Emergency objects are triggered by an internal error situation such as i.e. a
module is removed during operation, or a module signals an error. The bus
coupler then sends an emergency object to all connected devices (Broadcast),
to broadcast the error occurred. The informed bus subscribers can then react
accordingly by suitable error correction measures.
