Error Error definition and causes
code
2600H The cyclic processing does not finish
before the start timing for the next inter-
module synchronization cycle.
2610H An inter-module synchronization signal
error (synchronization loss) was detected.
3000H Any of the items in the module which is set
as a synchronization target in "Inter-
module Synchronization Setting" in
"System Parameter" are set as follows.
• "Station No./IP Address Setting Method"
in "Required Settings" is set to
"Program".
• "Setting Method of Basic/Application
Settings" under "Parameter Setting
Method" in "Required Settings" is set to
"Program".
• "Network Topology" in "Basic Settings" is
set to "Ring".
• Although a slave station in which
"Network Synchronous Communication"
in "Network Configuration Settings" of
"Basic Settings" is set to "Synchronous"
exists, the master/local module is not set
as a synchronization target module in
"Inter-module Synchronization Setting"
in "System Parameter".
• The control CPU of a master/local
module is a CPU module in which the
inter-module synchronization function
cannot be used.
3009H 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.
300AH • 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.
Action
• Check that the inter-module synchronous interrupt program (I44) was
written to the CPU module.
• Set the inter-module synchronization cycle to be longer than the current
value in "Fixed Scan Interval Setting of Inter-module Synchronization"
under "Inter-module Synchronization Setting" in "System Parameter".
• Change the setting value greater than the current setting for
"Communication Period Interval Setting" and "Transient Transmission
Time" in "Communication Period Setting" of the module parameter.
• If the value is not 0 in 'Transient transmission additional time (calculation
value)' (SW007A), add the value to "Communication Period Interval
Setting" and "Transient Transmission Time".
• Reduce the number of cyclic assignment points and the number of
connected slave modules, and correct the settings so that a shorter value
can be set for the communication period interval setting.
• Do not perform the online change in the CPU module.
• Take measures to reduce noise.
• Reset the CPU module, and run it again. If the same error occurs again
even after taking the above, the possible cause is a hardware failure of
the module, base unit, or extension cable. Please consult your local
Mitsubishi representative.
• Correct the parameters shown in cause.
• Check that the control CPU is CPU No.1. Update the firmware version of
the CPU module to a version supporting the inter-module synchronization
function with CC-Link IE TSN, or replace the CPU module with a CPU
module that supports this function.
Check the detailed information on 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 by executing module
diagnostics using the engineering tool, and correct the parameter setting
of the master station corresponding to the displayed parameter number.
• If the same error occurs again, the possible cause is a hardware failure of
the module. Please consult your local Mitsubishi representative.
