1803H Over the number of stations that can be
connected.
Reduce the number of CC-Link IE TSN Class B devices and
industrial switches (for CC-Link IE TSN Class B) to eight or less in
total for each port of the master station in the transmission path from
the master station to the CC-Link IE TSN Class B device of the end.
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 1Gbps, further on the end side than a
station with a communication speed of
100Mbps, a station with a communication
speed of 1Gbps is connected.
• With the master station with a communication
speed of 100Mbps, a station with a
communication speed of 1Gbps is connected.
• For a master station with a communication
speed of 100Mbps, "Communication Period
Setting" of the CC-Link IE TSN Class B station
with a communication speed of 100Mbps is set
to "Low-Speed".
• With the master station with a communication
speed of 1Gbps, "Communication Period
Setting" of the station with a communication
speed of 100Mbps is set to "Basic Period" or
"Normal-Speed" (4).
• 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.
• When the master station has a communication
speed of 1Gbps, stations with a communication
speed of 1Gbps and 100Mbps are connected
on the end side of the industrial switch.
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 1Gbps,
connect the station with a communication speed of 1Gbps on the
master station side rather than on the side where a station with a
communication speed of 100Mbps is connected.
• If the master station has a communication speed of 100Mbps, set
the communication speed of the device station to 100Mbps.
• If the master station has a communication speed of 100Mbps, set
"Communication Period Setting" of the CC-Link IE TSN Class B
station with a communication speed of 100Mbps to "Basic Period"
or "Normal-Speed" (4).
• If the master station has a communication speed of 1Gbps, set
"Communication Period Setting" to "Low-Speed" for the station
with a communication speed of 100Mbps.
• 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 1Gbps, do not
connect both a station with a communication speed of 1Gbps and
a station with the speed of 100Mbps on the end side of the
industrial switch.
