Network system for monitoring operation of monitored node
A network system includes: a monitored node (300) which is connected to a network (50) for isochronous transfer and asynchronous transfer and has a utility function; and a monitoring node (200) which monitors an operating state of the monitored node. The monitored node cyclically transmits a command (KA) representative of a normal operating state thereof to the monitoring node in one of isochronous channels on the network. When the monitoring node determines non-reception of the command representative of the normal operating state from the monitored node, the monitoring node transmits, to the monitored node, a real-time command to execute abnormality response processing such as resetting, power shut-off or disconnection from the network.
