Description and cause
Over the number of stations that can be
connected.
IP address duplication was detected.
The parameter setting is corrupted.
• The set value is out of the range. Or the
setting values of the master station and local
stations are not consistent.
• Parameters that are not supported by the
firmware version of the network module have
been set.
The result when the value set in
"Communication Period Interval Setting" in
"Communication Period Setting" under "Basic
Settings" of the master station is multiplied by
"Communication Period Setting" of the slave
station set in "Network Configuration Settings"
under "Basic Settings" is out of the range.
• The combination of the local station firmware
version and the master station firmware
version is incorrect.
• The set value is out of the range. Or the
setting values of the master station and local
stations are not consistent.
Multiple master stations were detected in the
network.
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".
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".
The value set in "Transient Transmission Time"
in "Communication Period Setting" under "Basic
Settings" of the master station is smaller than
the transient transmission time calculated using
the number of slave stations and the points of
slave stations set in "Network Configuration
Settings" under "Basic Settings".
Action
Reduce the number of authentication Class B devices to eight or
less for each port of the master station.
Check the IP addresses.
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 contact your local Mitsubishi representative.
• Check the detailed information of the error in "Module
Diagnostics" of the engineering tool, and correct the parameter
setting corresponding to the parameter number.
• 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 in "Module Diagnostics" of the
engineering tool. Correct the parameter settings described below
so that the result when the value set in "Communication Period
Interval Setting" in "Communication Period Setting" under "Basic
Settings" of the master station is multiplied by "Communication
Period Setting" of the slave station set in "Network Configuration
Settings" under "Basic Settings" becomes within 16ms.
• "Communication Period Interval Setting" in "Basic Settings"
• "Communication Period Setting" of the relevant slave station in
"Network Configuration Settings"
Set a value to "Communication Period Setting" of slave stations by
selecting a multiple value on "Multiple Period Setting" of
"Communication Period Setting" under "Basic Settings".
• Check the firmware versions of the master station and local
station. If the combination is incorrect, update the firmware
version of the older local station or that of the master station.
• Check the detailed information of the error in "Module
Diagnostics" of the engineering tool, and correct the parameter
setting of the master station corresponding to the parameter
number. If the same error occurs again, the possible cause is a
hardware failure of the module. Please contact your local
Mitsubishi representative.
• 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" as a
value equal to or larger than the value in the detailed information
displayed in "Module Diagnostics" using "Communication Period
Setting" under "Basic Settings" of the master station.
Set the value of "Cyclic Transmission Time" as a value equal to or
larger than the value in the detailed information displayed in
"Module Diagnostics" using "Communication Period Setting" under
"Basic Settings" of the master station.
Set "Communication Period Interval Setting" and "Cyclic
Transmission Time" so that the value of "Transient Transmission
Time" in "Communication Period Setting" under "Basic Settings" of
the master station is equal to or larger than the value shown in the
detailed information displayed in "Module Diagnostics".
