1802H During data link, overlapping IP addresses
have been detected.
1803H Over the number of stations that can be
connected.
1804H During data link, invalid connection
structure has been detected.
• A CC-Link IE TSN Class B station is
connected further on the end side than a
CC-Link IE TSN Class A station.
• With the master station with a
communication speed of 1 Gbps, further
on the end side than a station with a
communication speed of 100 Mbps, a
station with a communication speed of 1
Gbps is connected.
• With the master station with a
communication speed of 1 Gbps, there
is a 100 Mbps station whose
communication cycle setting is set to
Basic Period or Normal-Speed (4 times).
• With the master station with a
communication speed of 1 Gbps, a 1
Gbps station is connected.
• For a master station with a
communication speed of 100 Mbps,
"Communication Period Setting" of the
CC-Link IE TSN Class B station with a
communication speed of 100 Mbps is set
to "Low-Speed".
• The communication speed of the master
station and local station are not
matched.
■Multicast mode
• A CC-Link IE TSN Class A local station
is connected further on the end side than
a CC-Link IE TSN Class A remote
station.
• With the master station with a
communication speed of 1 Gbps,
stations with a communication speed of
1 Gbps and 100 Mbps are connected on
the end side via the switching hub.
Action
Change the IP address of devices with a duplicated IP address.
Reduce the number of CC-Link IE TSN Class B devices and TSN
switching hubs to eight or less in total in the transmission path from
the master station to the CC-Link IE TSN Class B device of the end.
Check the connection and setting on the end side of the station
shown in detailed information 2 and take the following actions.
• Connect the CC-Link IE TSN Class A station further on the end
than the CC-Link IE TSN Class B station.
• If the master station has a communication speed of 1 Gbps,
connect the station with a communication speed of 1 Gbps on
the master station side rather than on the side where a station
with a communication speed of 100 Mbps is connected.
• If the master station has a communication speed of 1 Gbps, set
"Communication Period Setting" to "Low-Speed" for the station
with a communication speed of 100 Mbps.
• If the master station has a communication speed of 1 Gbps, set
the station with a communication speed of 100 Mbps as a
standard station.
• If the master station has a communication speed of 100 Mbps,
set the communication speed of the device station to 100 Mbps.
• If the master station has a communication speed of 100 Mbps,
set "Communication Period Setting" of the CC-Link IE TSN Class
B station with a communication speed of 100 Mbps to "Basic
Period" or "Normal-Speed" (4).
• Set the same communication speed for the master station and
local station.
■Multicast mode
• Connect the CC-Link IE TSN Class A remote station further on
the end than the CC-Link IE TSN Class A local station.
• If the master station has a communication speed of 1 Gbps, do
not connect a station with a communication speed of 1 Gbps and
100 Mbps on the end side via the switching hub.
