Error Error definition and causes
code
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 with a
communication speed of 1Gbps, stations
with a communication speed of 1Gbps
and 100Mbps are connected on the end
side of the switching hub.
1805H • The total cyclic data size of all slave
stations on the CC-Link IE TSN Class A
device side that form a boundary
between CC-Link IE TSN Class B and
CC-Link IE TSN Class A exceeds 2K
bytes.
• The total cyclic data size of all slave
stations on the side of the station with a
communication speed of 100Mbps at the
boundary between the station with a
communication speed of 1Gbps and the
station with a communication speed of
100Mbps exceeds 2K bytes.
1806H • When "TSN HUB Setting" is set to "Not
to Use TSN HUB", connection of the
CC-Link IE TSN Class B devices in a
star topology has been detected.
• A CC-Link IE TSN Class B device is
connected further on the end side than a
CC-Link IE TSN Class A device.
1811H A stop error has been detected in the CPU
module.
1830H Number of reception requests of transient
transmission (link dedicated instruction)
exceeded the upper limit of simultaneously
processable requests.

19.1 Error Codes When a Module Error Occurs
Action
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 side 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 slave 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
side 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
100Mbps on the end side of the switching hub.
Check the connection and setting on the end side of the station shown in
detailed information 2 based on the error definition and cause and take the
following actions.
• Ensure that the total cyclic data size of all slave stations on the CC-Link IE
TSN Class A device side that form a boundary between CC-Link IE TSN
Class B and CC-Link IE TSN Class A does not exceed 2K bytes.
• Do not set the total cyclic data size of all slave stations on the side of the
station with a communication speed of 100Mbps at the boundary between
the station with a communication speed of 1Gbps and the station with a
communication speed of 100Mbps to exceed 2K bytes. For calculation of
the total cyclic data size, refer to the following. ( Page 526
Communication cycle intervals)
• Disconnect the switching hub connected with the CC-Link IE TSN Class B
device.
• Set "TSN HUB Setting" to "Use TSN HUB".
• Connect the CC-Link IE TSN Class A device further on the end side than
the CC-Link IE TSN Class B device.
Check the error of the CPU module and take action using the module
diagnostics of the engineering tool.
Execute the instruction again after lower the transient transmission usage
frequency.
