3.2 Function List of CC-Link IE Controller Network
Description
Automatically returns the station disconnected from the network due to a data
link error to the network when it recovers and restarts data link.
Continues data link with normally operating stations even if a cable
disconnection or faulty station occurs.
Continues data link with a normal station (sub-control station) that serves as a
control station even if the control station goes down.
Disconnects only the normal station where an error occurs, and continues the
data link with the stations that are operating normally. In a line topology, all
stations connected after the faulty station are disconnected.
Continues data link among the normally operating stations without being
disrupted at the power-down station even if the CPU module power supply
goes down in a network. Data link is also continued between more than one
station where CPU module power supply has gone down.
Description
Checks the status of CC-Link IE Controller Network using the engineering tool.
The error locations, error causes, and corrective actions can be checked in the
engineering tool.
Checks the hardware inside the CC-Link IE Controller Network-equipped
module. This test should be conducted when the communication is unstable.
Checks the connection status of the Ethernet cables.
Checks whether the communication route for transient transmission from the
own station to the destination station is correct or not.
Checks whether no error occurs in the communication route when the IP
packet transfer function is used.
