List of Error Codes

If an error occurs during operation, the A/D converter module stores the error code into 'Latest error code' (Un\G0) of the
buffer memory. In addition, 'Error flag' (XF) turns on. Turning on 'Error clear request' (YF) allows clearing of the error code of
'Latest error code' (Un\G0), and turning off of 'Error flag' (XF).
Error codes of the A/D converter module are classified in minor errors or moderate errors.
• Minor error: This error is caused by a setting failure of programs and parameters. The A/D conversion continues with the
parameter setting before the change. (1000H to 1FFFH)
• Moderate error: Hardware failures are included. The A/D conversion do not continue. (2000H to 2FFFH, 3000H to 3FFFH)
The following table lists the error codes that may be stored.
 in an error code: This symbol indicates the number of the channel where an error has occurred. A numerical value of 0 to 3
is used to correspond to CH1 to 4.
(CH1: 0, CH2: 1, CH3: 2, CH4: 3)
 in an error code: For what this symbol indicates, refer to Description and cause.

Description and cause
There is no error.
The number of the offset/gain settings has exceeded
the guaranteed maximum number.
Offset/gain values cannot be restored with the
module-specific backup parameter.
The module-specific backup parameter has not been
created.
A value other than Interrupt resend request (0) and
No interrupt resend request (1) is set in Interrupt
factor generation setting [n].
 indicates the interrupt setting related to the error
as follows:
0: Setting 1 to F: Setting 16
A value out of the range is set in Condition target
setting [n].
 indicates the interrupt setting related to the error
as follows:
0: Setting 1 to F: Setting 16
A value out of the range is set in Condition target
channel setting [n].
 indicates the interrupt setting related to the error
as follows:
0: Setting 1 to F: Setting 16
The same combination of condition target and
condition target channel are set to multiple interrupt
settings.
(Setting 0: All channels in Condition target channel
setting is regarded the same as setting 1: CH1 to 4:
CH4.)
For one channel, both "5: A/D conversion
completed" and "7: Logging read" are set as an
interrupt condition target.
The G(P).OGSTOR instruction has been executed in
offset/gain setting mode.
The G(P).OGSTOR instruction has been executed
continuously or a setting value has been
continuously written to the flash memory 26 times or
more in the offset/gain setting.
Action

Any further setting of offset/gain values may not be
reflected correctly.
The module-specific backup parameter file may be
damaged. Readjust the user range.
Check the free space on the data memory of the
control CPU and the SD memory card, and recreate
a module-specific backup parameter.
For how to create module-specific backup
parameters, refer to the following.
Page 140 Creating and updating a module-
specific backup parameter
Set Interrupt factor generation setting [n] to Interrupt
resend request (0) or No interrupt resend request
(1).
■Normal mode (low speed: 20s/CH), inter-module
synchronization mode
Set Condition target setting [n] to Disable (0) to
Logging read (7).
■Normal mode (high speed: 1s/CH), simultaneous
conversion mode
Set Condition target setting [n] to Disable (0) or
Continuous logging data storage (8).
Set Condition target channel setting [n] to All
channels (0) to CH4 (4).
For each interrupt setting, check and correct the
combination of all Condition target setting and
Condition target channel setting.
For each channel, set either "5: A/D conversion
completed" or "7: Logging read" in Condition target
setting [n].
Do not execute the G(P).OGSTOR instruction in the
offset/gain setting mode.
For the G(P).OGSTOR instruction, execute it only
once per module. For the offset/gain setting, write
the setting value only once per setting.
