TROUBLESHOOTING
Error code
• A module is installed in the position of slot 65 or higher.
• A module is installed in the position of the slot number that exceeds
the number of slots set for the base unit.
2124 • A module is installed in the slot where I/O points of 4096 or higher are
assigned.
• A module is installed in the slot whose assigned I/O points cross over
the boundary of 4096.
• A module that cannot be recognized is mounted.
2125
• No response returns from an intelligent function module.
In the multiple CPU system, CPU modules are configured as follows:
• The slot on the left of a CPU module is empty.
• A CPU module other than High Performance model QCPUs is
mounted on the left of a High Performance model QCPU.
• When CPU No.1 is a High Performance model QCPU, a CPU module
2126 other than C Controller modules is mounted on the right of a C
Controller module.
• When CPU No.1 is a C Controller module, a programmable controller
CPU is mounted on the right of the C Controller module.
• When CPU No.1 is a Basic model QCPU, a CPU module is mounted
on the right of the C Controller module.
In the multiple CPU system, an intelligent function module
2150 incompatible with the multiple CPU system is set to be controlled by a
CPU other than CPU No.1.
• No parameter file is set.
2200
• The parameters were written to a drive different from a valid one.
• One command (one line) in the script file has 129 or more characters.
2502 • The command in the script file cannot be executed. (An error in the
syntax, or no command exists.)
Error details and cause
16.3 Actions to be Taken When the ERR. LED is On or Flashing
Corrective action
• Remove the module in slot 65 or higher.
• Remove the module installed in the position of the slot number that
exceeds the number of slots set for the base unit.
• Remove the module installed in the slot where 4096 points or higher
are assigned.
• Replace the last module with a module whose I/O points do not
exceed 4096.
• Mount applicable modules.
• The intelligent function module is faulty. Please consult your local
Mitsubishi service center or representative, explaining the details of
the problem.
Perform the following.
For CPU module positions in a multiple CPU system, refer to Page 12-
1, Section 12.1.
• Eliminate any empty slot space between CPU modules. (An empty
slot must be set on the right side of CPU modules.)
• Replace the module other than High Performance model QCPUs on
the left of the High Performance model QCPU with a High
Performance model QCPU.
• Remove the CPU module other than C Controller modules on the
right of the C Controller module.
• Remove the programmable controller CPU mounted on the right of
the C Controller module.
• Remove the CPU module mounted on the right of the C Controller
module.
• Change the module to an intelligent function module that supports
the multiple CPU system (function version B or later).
• Change the control CPU setting for the intelligent function module to
CPU No.1.
• Set the parameter file.
• Write the parameters to a valid drive.
Correct the description of the error script file as shown below, and
restart the C Controller module.
• Reduce the number of characters for one command (one line) in the
script file to 128 or less.
• Confirm no error in the syntax and the presence of a command.
