Lists of Error Codes
This section describes error codes.
Error codes are classified by error number as follows.
(1) List of error codes (0000H to 3FFFH, D529H, D52BH)
The errors are classified into the following three types.
If an error has occurred, check that the D LINK LED is on and take actions as listed below.
(a) List of error codes (0000H to 015FH)
Error code Classification Reference
0000H to 3FFFH, D529H, D52BH Temperature control module error Page 271, Section 11.2 (1)
D000H to DFFFH (D529H and
D52BH excluded)
CC-Link IE Field Network error (communication system error) Page 276, Section 11.2 (2)
Classification Description
Major error An error where the module cannot be recovered. The RUN LED turns off.
Moderate error
An error where the module cannot continue to operate. The ERR. LED turns on. However, with some moderate errors, the
module keeps operating using the setting value of normal operation.
Minor error An error where the module can continue to operate. The ERR. LED flashes.

Error details
*1
Action
0001H Major error Hardware error
The operation differs
depending on the
symptom.
0 is stored in Error occurrence
address, Process value (PV),
Manipulated value (MV), and
Set value (SV).
• Check that the terminal block or the cold
junction temperature compensation
resistor is not disconnected or loose.
(Check the cold junction temperature
compensation resistor only for the
NZ2GF2B-60TCTT4.)
• Turn off and on the power of the system.
If the same error occurs again, the
possible cause is a module failure.
Please consult your local Mitsubishi
representative.
0003H Moderate error
Either of the
following
operations is being
performed.
• While the
module is
operating, data
is being written
to the area
where data can
be written only
during the
module stop
*2
.
• Initial data
setting request
flag (RY9) was
turned on during
the module
operation.
• The data written is
retained.
• The operating
status remains
same as before
the error
occurrence.
• The address of remote
buffer memory area where
an error has occurred is
stored in Error occurrence
address. (If the parameter
has not been changed,
FFFFH is stored in Error
occurrence address. In
addition, 0 is stored in
Process value (PV),
Manipulated value (MV),
and Set value (SV).
• The process value of the
error channel is stored in
Process value (PV).
• The manipulated value of
the error channel is stored
in Manipulated value (MV).
• The set value of the error
channel is stored in Set
value (SV).
Follow the instructions below and clear the
error.
1. Stop operation for all channels.
2. Set a correct value and turn on and off
Initial data setting request flag (RY9).
If the changed parameter is the
changeable one during operation and an
error (0003H) has occurred, the error also
can be cleared by following the instructions
below.
1. Turn off Initial data setting request flag
(RY9).
2. Turn on and off During operation setting
change instruction (RY10).
If FFFFH is stored in Error occurrence
address, the error also can be cleared by
following the instructions below.
1. Turn off Initial data setting request flag
(RY9).
2. Turn on and off Error clear request flag
(RYA).
