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 slave
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 slave stations set in "Network
Configuration Settings" under "Basic
Settings".

19.1 Error Codes When a Module Error Occurs
Action
• Check the Announce frame send cycle parameter setting value of the
device operating as the grandmaster. When the RJ71GN11-T2 or
RJ71GN11-EIP 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 RJ71GN11-T2 or
RJ71GN11-EIP 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 RJ71GN11-T2 or RJ71GN11-
EIP 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.
Set the same parameter setting values for "Network No." and "Station No."
of the local station to the setting values of 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 value in the detailed information exceeds the upper limit of
"Communication Period Interval Setting" that can be set on 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 value does not exceed the upper limit of
"Communication Period Interval Setting".
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 value in the detailed information exceeds the upper limit of "Cyclic
Transmission Time" that can be set on 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 value does not exceed the upper limit of "Cyclic Transmission
Time".
