Error Error definition and causes
code
300BH The Announce frame send cycle
parameter error was detected.
300CH A propagation delay send cycle parameter
error was detected.
300DH The Sync frame send cycle parameter
error was detected.
300EH The set values of the master station and
local station do not match.
300FH Multiple master stations were detected in
the network.
3010H The value set in "Communication Period
Interval Setting" in "Communication Period
Setting" under "Basic Settings" of the
master station is smaller than the
communication cycle interval calculated
by the number of stations and points of
device stations that was set in "Network
Configuration Settings" under "Basic
Settings".
3011H The value set in "Cyclic transmission time"
in "Communication Period Setting" under
"Basic Settings" of the master station is
smaller than the cyclic transmission time
calculated by the number of stations and
points of device stations set in "Network
Configuration Settings" under "Basic
Settings".
3012H The Motion module not compatible with
network synchronous communication is
set as the master station, and "Network
Synchronous Communication" in the
device station in "Network Configuration
Settings" under "Basic Settings" of the
master station is set to "Synchronous".

4.5 List of Error Codes
Action
• Check the Announce frame send cycle parameter setting value of the
device operating as the grandmaster. When the Motion module is
operating as the grandmaster, reset the CPU module, and run it again.
• If the same error occurs again even after taking the above measure, the
possible cause is a hardware failure of the module. Please consult your
local Mitsubishi representative.
• Check the propagation delay send cycle parameter setting value of the
device operating as the grandmaster. When the Motion module is
operating as the grandmaster, reset the CPU module, and run it again.
• If the same error occurs again even after taking the above measure, the
possible cause is a hardware failure of the module. Please consult your
local Mitsubishi representative.
• Check the Sync frame send cycle parameter setting value of the device
operating as the grandmaster. When the Motion module is operating as
the grandmaster, reset the CPU module, and run it again.
• If the same error occurs again even after taking the above measure, the
possible cause is a hardware failure of the module. Please consult your
local Mitsubishi representative.
For "Network No." and "Station No." of the local station, set the same values
as the ones set in the master station.
• Connect only one master station on the same network.
• After taking the above action, power off and on or reset all stations where
the error was detected.
Set the value of "Communication Period Interval Setting" over the value in
the detailed information displayed by module diagnostics using
"Communication Period Setting" under "Basic Settings" of the master station.
If the detailed information value exceeds the upper limit of "Communication
Period Interval Setting" that can be set in the master station, reduce the
number of modules connected to the master station and the number of link
devices assigned to each module in "Network Configuration Settings", so
that the upper limit of "Communication Period Interval Setting" is not
exceeded.
Set the value of "Cyclic Transmission Time" over the value in the detailed
information displayed by module diagnostics using "Communication Period
Setting" under "Basic Settings" of the master station.
If the detailed information value exceeds the upper limit of "Cyclic
Transmission Time" that can be set in the master station, reduce the number
of modules connected to the master station and the number of link devices
assigned to each module in "Network Configuration Settings", so that the
upper limit of "Communication Period Interval Setting" is not exceeded.
• Update the Add-on baseSystem version to "1.16" or later.
• In "Network Configuration Settings" under "Basic Settings" of the master
station, set "Network Synchronous Communication" of the device station
to "Asynchronous".
