*1 Information of the module that has detected an error is stored in Error code details 1 of Error history data  (address:
0A00H to 0AEFH). (The following is an example of Error history data 1 (address: 0A00H to 0A0FH).)
Error code details 1
(address: 0A06H)
*2 The start address of the remote buffer memory areas specified with the REMFR/REMTO instruction is stored in Error
code details 1 of Error history data  (address: 0A00H to 0AEFH).
*3 The remote buffer memory address of the parameter that has detected an error is stored in Error code details 1 of Error
history data  (address: 0A00H to 0AEFH).
The set value upon an error is stored in Error code details 2. The setting values of the lower 16 bits and higher 16 bits
are respectively stored in Error code details 2 and Error code details 3 of Input OFF delay setting and Fast logic setting
that have a setting value of 32 bits.
*4 Mode switch setting change (error code: 0204H) is not cleared even if five seconds have passed after the error occurred.
During the error, the I/O module keeps operating in the mode before the Mode switch (address: 0003H) change.
To clear the error in the previous mode, set the previous value to Mode switch (address: 0003H) and turn on and off
Operation condition setting request flag (RWw0.b9).

Data for b2 to b15 are fixed to "0".
0: The extension module 1 is normal.
1: The extension module 1 has an error.
0: The main module is normal.
1: The main module has an error.
■When the main module is a 16-point module
Correct the parameter settings.
• Correct the set value in Input OFF delay setting X
(address: 0110H to 012FH, 0210H to 022FH) to a value
within the setting range (0 to 150000). (Check the
addresses of 0110H to 012FH of a main input module and
0210H to 022FH of an extension input module.)
■When the main module is a 32-point module
Correct the parameter settings.
• Correct the set value in Input OFF delay setting X
(address: 0110H to 014FH, 0110H to 012FH, 0210H to
022FH) to a value within the setting range (0 to 150000).
(Check the addresses of 0110H to 014FH of a main input
module, 0110H to 012FH of a main I/O combined module,
and 0210H to 022FH of an extension input module.)
Correct the parameter settings.
• Check that the set value in Cyclic data update watch time
setting (address: 0002H) is within the setting range (0 to
20).
Correct the parameter settings.
• Check that the set value in Mode switch (address: 0003H)
is within the setting range (Normal mode (0), Automatical
judgment mode (9)).
Correct the parameter settings.
• Check that the set value in Initial operation setting
(address: 0004H) is within the setting range (With initial
processing (0), Without initial processing (1)).
• A malfunction may have occurred due to noise or others.
Check the cable distance or grounding condition of each
device. Then take measures against noise.
• If the same error occurs again, the hardware of the
module may be in failure. Please consult your local
Mitsubishi representative.
