error code
• 5 or more MELSECNET/H modules have been installed in a whole
multiple CPU system.
• 5 or more Q series Ethernet interface modules have been installed
in a whole multiple CPU system.
2106
• 5 or more MELSECNET/H modules have been installed.
• 5 or more Q series Ethernet interface modules have been installed.
• The same network number or same station number is duplicated in
the MELSECNET/H network system.
The start X/Y set in Parameter's I/O assignment setting is overlapped
2107
with the one for another module.
• A network module for A2UCPU (A1SJ71LP21, A1SJ71BR11,
A1SJ71LR21, A1SJ71AP21, A1SJ71AR21, or A1SJ71AT21B) is
2108 mounted.
• A network module for Q2AS (A1SJ71QLP21(S), A1SJ71QBR11 or
A1SJ71QLR21) is mounted.
• In a single CPU system, the QA B or QA1S B was used as a
base unit.
2120
• In a multiple CPU system configuration, the C Controller module
was set as a CPU controlling modules on the QA B or QA1S B.
The CPU module is installed to other than the CPU slot and slots 0 to
2121
2.
2122
QA1S B is used to the main base unit.
• A module is installed to the 65th or higher slot.
• A module is installed to the slot whose number is greater than the
number of slots specified in the base assignment.
2124 • A module is installed to the location corresponding to the I/O points
of 4,096 or greater.
• A module is installed to the slot whose assigned I/O range include
the limit of 4096.
• A module that cannot be recognised has been installed.
2125
• There was no response form the intelligent function module.
In a multiple CPU system, the CPU module configuration is as
described below.
• There are empty slots on the left-hand side of the CPU module.
• A CPU module other than the High Performance model QCPU is
mounted on the left-hand side of the High Performance model
QCPU.
• When CPU No.1 is the High Performance model QCPU, a CPU
2126
module other than the C Controller module is mounted on the right-
hand side of the C Controller module.
• When CPU No.1 is the C Controller module, a programmable
controller CPU is mounted on the right-hand side of the C Controller
module.
• When CPU No.1 is the Basic model QCPU, a CPU module is
mounted on the right-hand side of the C Controller module.
In a multiple CPU system, the control CPU of the intelligent function
2150 module incompatible with the multiple CPU system is set to other than
CPU No.1.
* 2 In the "Error time operation mode" on the <<System setting>> tab of the C Controller setting utility, the CPU operation status after error
occurrence can be set to "Stop" or "Continue". (The LED display also changes according to the setting.)
Error description and cause Corrective action
• Reduce the number of MELSECNET/H modules to 4 or less in the
whole multiple CPU system.
• Reduce the number of Q series Ethernet modules to 4 or less in the
whole multiple CPU system.
• Reduce the number of MELSECNET/H modules to 4 or less.
• Reduce the number of Q series Ethernet modules to 4 or less.
• Check the network numbers and station numbers.
Make the Parameter's I/O assignment setting again so that it is
consistent with the actual status of the intelligent function modules.
Replace the network module with a MELSECNET/H module.
• Use the Q B as a base unit.
• Set the modules on the QA B or QA1S B to be controlled by the
High Performance model QCPU.
Check the mounting position of the C Controller module, and mount it
to the correct slot.
Change the main base unit to the Q B.
• Remove the module installed to the 65th or later slot.
• Remove the module installed to the slot whose number is greater
than the number of slots specified in the base assignment setting.
• Remove the module installed to the location of I/O points, 4,096 or
greater.
• Replace the last module with a module whose I/O points do not
exceed 4,096.
• Install an applicable module.
• The intelligent function module is faulty. Please consult your local
Mitsubishi service center or representative, explaining the details of
the problem.
Take the following actions.
Refer to Section 13.1 for the CPU module's mounting position in a
multiple CPU system.
• Eliminate any empty slot space between CPU modules by moving
the mounted modules to empty slots. (Set empty slots on the right-
hand side of the CPU modules.)
• Remove the module other than the High Performance model QCPU
mounted on the left-hand side of the High Performance model
QCPU, and move the High Performance model QCPU to the left.
• Remove the CPU module other than the C Controller module
mounted on the right-hand side of the C Controller module.
• Remove the programmable controller CPU mounted on the right-
hand side of the C Controller module.
• Remove the CPU module mounted on the right-hand side of the C
Controller module.
• Change the intelligent function module for the one compatible with
the multiple CPU system (function version B or later).
• Change the setting of the control CPU for the intelligent function
module incompatible with the multiple CPU system to CPU No.1.
