Appendix 1.4 List Of Error Codes (2000 To 2999) - Mitsubishi Electric Q26UD(E)HCPU User Manual

Appendix 1.4
The following table shows the error messages, the error contents and causes, and the corrective actions for the error
codes (2000 to 2999).
Error
Error and cause
code
[UNIT VERIFY ERR.]
In a multiple CPU system, a CPU module
incompatible with the multiple CPU system is
mounted.
■Collateral information
• Common information: Module No. (Slot No.)
• Individual information: -
■Diagnostic timing
• When an END instruction executed
[UNIT VERIFY ERR.]
The I/O module status is different from the I/O
module information at power ON.
• The I/O module (including the intelligent function
module) is nearly disconnected or removed
while the system is running.
■Collateral information
• Common information: Module No. (Slot No.)
[For Remote I/O network] and Network
2000
No./Station No.
• Individual information: -
■Diagnostic timing
• When an END instruction executed
[UNIT VERIFY ERR.]
The I/O module status is different from the I/O
module information at power ON.
• The I/O module (including the intelligent function
module/special function module) is nearly
disconnected, removed, or mounted while the
system is running.
■Collateral information
• Common information: Module No. (Slot No.)
[For Remote I/O network] Network No./Station
No.
• Individual information: -
■Diagnostic timing
• Always
[UNIT VERIFY ERR.]
During operation, a module was mounted on the
slot where the empty setting of the CPU module
was made.
2001 ■Collateral information
• Common information: Module No. (CPU No.)
• Individual information: -
■Diagnostic timing
• Always
[BASE LAY ERROR]
• More than applicable number of extension base
units have been used.
• When a GOT was bus-connected, the CPU
module was reset while the power of the GOT
2010
was OFF.
■Collateral information
• Common information: Base No.
• Individual information: -
■Diagnostic timing
• At power-on/At reset

Corrective action
Replace the CPU module incompatible with
the multiple CPU system with a CPU module
compatible with the multiple CPU system.
• Read common information of the error
using the programming tool to identify the
numeric value (module No.). Check the
module corresponding to the value and
replace it as necessary.
• Monitor SD150 to SD157 using the
programming tool to identify the module
whose data bit is "1". Check the
corresponding module and replace it as
necessary.
• Read common information of the error
using the programming tool to identify the
numeric value (module No.). Check the
module corresponding to the value and
replace it as necessary.
• Monitor SD1400 to SD1431 using the
programming tool to identify the module
whose data bit is "1". Check the
corresponding module and replace it as
necessary.
• When a GOT is bus-connected to the main
base unit or extension base unit, check the
connection status of the extension cable
and the grounding status of the GOT.
During operation, do not mount a module on
the slot where the empty setting of the CPU
module was made.
• Use the allowable number of extension
base units or less.
• Power on the programmable controller and
GOT again.
