1805H • The cyclic data size exceeds 2K bytes
in total for all device stations on the CC-
Link IE TSN Class A device side at the
boundary between CC-Link IE TSN

Class A devices.
• The total cyclic data size of all device
stations on the side of the station with a
communication speed of 100 Mbps at
the boundary between the station with a

1806H • A connection with a TSN hub was
detected when "TSN HUB Setting" was
set to "Not to Use TSN HUB".

network.
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.
1845H The amount of processing of transient
transmission (link dedicated instruction) is
too much and transient transmission
cannot be performed.
1D10H Cyclic transmission skip occurred.

calculated by the inter-module
synchronization function exceeds
allowable range.

4.5 List of Error Codes
Action
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.
• Do not allow the cyclic data size to exceed 2K bytes in total for all device
stations on the CC-Link IE TSN Class A device side at the boundary
between CC-Link IE TSN Class B devices and CC-Link IE TSN Class A
devices.
• Do not set the total cyclic data size of all device stations on the side of the
station with a communication speed of 100 Mbps at the boundary between
the station with a communication speed of 1 Gbps and the station with a
communication speed of 100 Mbps to exceed 2K bytes.
• Disconnect the switching hub connected to the CC-Link IE TSN Class B
device.
• Set "TSN HUB Setting" to "Use TSN HUB".
• Connect CC-Link IE TSN Class A stations closer to the end than CC-Link
IE TSN Class B stations.
Correct the wiring status.
Check the error of the CPU module and take action using the module
diagnostics of the engineering tool.
Execute the instruction again after lowering the transient transmission usage
frequency.
Correct the transient transmission (link dedicated instruction) execution
count.
• Increase the value for the inter-module synchronization cycle set in "Fixed
Scan Interval Setting of Inter-module Synchronization" under "Inter-
module Synchronization Setting" in "System Parameter" so that the
execution time of synchronization interrupt program does not exceed the
inter-module synchronization cycle.
• Increase the value for "Communication Period Interval Setting" and
"Transient Transmission Time" in "Communication Period Setting" of the
module parameter.
• If the value in 'Transient transmission addition time (calculation value)'
(SW007A) is not 0, add the value (μs unit) to "Communication Period
Interval Setting" and "Transient Transmission Time".
• Reduce the program processing time by reducing the program volume so
that the execution time of synchronization interrupt program does not
exceed the inter-module synchronization cycle.
• Reduce the refresh processing time by reducing the data targeted for
synchronization refreshing so that the execution time of synchronization
interrupt program does not exceed the inter-module synchronization cycle.
• Set modules not requiring synchronization to asynchronous so that the
execution time of synchronization interrupt program does not exceed the
inter-module synchronization cycle.
• Do not perform the online change in the CPU module.
• Take measures to reduce noise.
• If the same error occurs multiple times even after taking the above, the
possible cause is a hardware failure of the module or base unit. Please
consult your local Mitsubishi representative.
