Function

communication function
Reserved station specification
Description
Disconnects only the slave 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.
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 normal stations even if a cable disconnection or faulty
station occurs. All stations after the cable disconnection point or faulty station
are disconnected in a line topology. By using this function with ring topology,
data link continues with normal stations.
Allows the submaster station to control slave stations instead of the master
station when the master station is disconnected in a system where the master
station and submaster station are connected on the same network. Using this
function prevents the entire network from going down due to disconnection of
the master station.
Description
Checks the status of CC-Link IE Field Network using the engineering tool. The
error locations, error causes, and corrective actions can be checked in the
engineering tool.
Checks the hardware of the master/local 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 path when the IP
packet transfer function is used.
Description
Synchronizes control intervals between slave stations over CC-Link IE Field
Network according to synchronization cycle specified in the master station.
This allows different slave stations on the same network to operate with the
same timing.
( MELSEC iQ-R Inter-Module Synchronization Function Reference

Specifies stations reserved for future use. The reserved stations are not
actually connected, but counted as connected stations. The stations are not
detected as faulty stations even though they are not actually connected.
