Code
[<CHK>ERR ***-***]
Error detected by the CHK instruction.
(The "***" portion of the error message indicates
the numbers of contact and coil that have been
detected.)

■Collateral information
• Common information: Program error location
• Individual information: Failure No.
■Diagnostic Timing
• When instruction executed
[BOOT OK]
Storage of data onto ROM was completed
normally in automatic write to standard ROM.
(BOOT LED also flickers.)
9020 ■Collateral information
• Common information:-
• Individual information:-
■Diagnostic Timing
• At power-on/At reset
[CONT. UNIT ERROR]
In the multiple CPU system, an error occurred in
the CPU module other than the Process CPU and
High Performance model QCPU.

*2 For the Basic model QCPU, it can be turned on and off by the LED control function. (For the High Performance model
CPU, Process CPU, Redundant CPU, Universal model QCPU, and LCPU, it can only turned on.)
T
*8 This applies if the function version is B or later.
*9 This applies to the CPU modules when the first five digits of the serial number is "04012".
*18 This applies to the Universal model QCPU except for the Q00UJCPU.
*20 This applies to the Universal model QCPU except for the Q00UJCPU, Q00UCPU, Q01UCPU, and Q02UCPU.
*23 The product name is the Bus interface driver software package of MELSEC-Q series compatible PC CPU module
*24 The Basic model QCPU does not have the USER LED.
*30 USER LED turns on.
*31 This applies when the first five digits of the serial number is "13102" or later.
Appendix 1.10
An error can be cleared as far as the CPU module continues its operation regardless of the error.
1.
Remove the error cause.
2.
Store the error code to be cleared in SD50.
3.
Turn on SM50.
4.
The error is cleared.
When the error in the CPU module is cleared, the special relay and special register or LEDs relating to the error return
to the status before the error. If the same error occurs after clearing the error, the error will be registered to the error
history again.
When multiple annunciators are detected, only the first annunciator detected can be cleared. For details on clearing
errors, refer to the following.

*30
Read the individual information of the error using
the programming tool to identify the numeric value
(error number). Check the program corresponding
to the value.
Use the DIP switches to set the valid parameter
drive to the standard ROM. Then, switch power on
again, and perform boot operation from the
standard ROM.
To check the details of the error, connect a
programming tool to the corresponding CPU
module.
