List of Error Codes

If an error occurs during operation, a temperature input 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) clears the error code in 'Latest error
code' (Un\G0) and turns off 'Error flag' (XF). Error codes of a temperature input module are classified in minor errors or
moderate errors.
• Minor error: This error is caused by the setting failure of programs and parameters. The temperature conversion continues
with the parameter setting before the setting change. (1000H to 1FFFH)
• Moderate error: Hardware failures. The temperature conversion does not continue. (3000H to 3FFFH)
: This symbol indicates the number of the channel where an error has occurred. A numerical value of 0 to 7 is used to
correspond to CH1 to 8.
(CH1: 0, CH2: 1, CH3: 2, CH4: 3, CH5: 4, CH6: 5, CH7: 6, CH8: 7)
: For what this symbol indicates, refer to Description and cause of error.

Description and cause
There is no error.
The number of the offset/gain settings has exceeded
the guaranteed maximum number.
Offset/gain values have not been restored using the
module-specific backup parameter.
A module-specific backup parameter has not been
created.
A value other than 0 to 1 is set in Interrupt factor
generation setting [n].
 indicates the interrupt setting related to the error
as below:
Setting 1: 0, Setting 2: 1, Setting 3: 2, Setting 4: 3,
Setting 5: 4, Setting 6: 5, Setting 7: 6, Setting 8: 7,
Setting 9: 8, Setting 10: 9, Setting 11: A, Setting 12:
B, Setting 13: C, Setting 14: D, Setting 15: E, Setting
16: F
A value other than 0 to 7 is set in Condition target
setting [n].
 indicates the interrupt setting related to the error
as below:
Setting 1: 0, Setting 2: 1, Setting 3: 2, Setting 4: 3,
Setting 5: 4, Setting 6: 5, Setting 7: 6, Setting 8: 7,
Setting 9: 8, Setting 10: 9, Setting 11: A, Setting 12:
B, Setting 13: C, Setting 14: D, Setting 15: E, Setting
16: F
A value other than 0 to 8 is set in Condition target
channel setting [n].
 indicates the interrupt setting related to the error
as below:
Setting 1: 0, Setting 2: 1, Setting 3: 2, Setting 4: 3,
Setting 5: 4, Setting 6: 5, Setting 7: 6, Setting 8: 7,
Setting 9: 8, Setting 10: 9, Setting 11: A, Setting 12:
B, Setting 13: C, Setting 14: D, Setting 15: E, Setting
16: F
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.
The G(P).OGSTOR instruction has been executed
on a module different from the one on which the
G(P).OGLOAD instruction was executed.
The G(P).OGSTOR instruction has been executed
ahead of the G(P).OGLOAD instruction.
Action

Any further setting of offset/gain values may not be
reflected correctly.
The possible cause is a damage of the module-
specific backup parameter file. Adjust the user range
again.
Check the free space on the data memory or SD
memory card of the control CPU, and create a
module-specific backup parameter again.
Set 0 or 1 in Interrupt factor generation setting [n].
Set a value of 0 to 7 in Condition target setting [n].
Set a value of 0 to 8 in Condition target channel
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.
Execute the G(P).OGLOAD and G(P).OGSTOR
instructions on the same module. As the other way,
execute the G(P).OGLOAD instruction on the
module whose data is to be restored, and then
execute the G(P).OGSTOR instruction on the
module to which the data is to be restored.
