1805H • The total cyclic data size of all device 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 devices
exceeds 2K bytes.
• The total cyclic data size of all device 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.
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 device 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 devices
does not exceed 2K bytes.
• Do not set the total cyclic data size of all device 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.

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.
• Disconnect the industrial switch connected with the CC-Link IE
TSN Class B device.
• Set "TSN HUB Setting" to "Use TSN HUB".

1811H A stop error has been detected in the CPU
module.
Check the error of the CPU module in "Module Diagnostics" of the
engineering tool and take action.

1830H Number of reception requests of transient
transmission (link dedicated instruction) exceeded
the upper limit of simultaneously processable
requests.
Lower the transient transmission usage frequency, and retry the
operation.

1845H Too much processing of transient transmission
(link dedicated instruction) and cannot perform
transient transmission.
Correct the transient transmission (link dedicated instruction)
execution count.

20E0H The module cannot communicate with the CPU
module.
The hardware failure of the CPU module may have been occurred.
Please consult your local Mitsubishi representative.

2160H IP address duplication was detected. Check the IP addresses. 
2220H • Parameters that are not supported by the
firmware version of the network module have
been set.
• The parameter setting is corrupted.
• Check the firmware version of the network module. If parameters
that are not supported are set, update the firmware version or
correct the parameters.
• Check the detailed information of the error in "Module Diagnostics"
of the engineering tool, and write the displayed parameter. If the
same error occurs again, the possible cause is a hardware failure
of the module. Please consult your local Mitsubishi representative.
