A-3-1 Fatal Errors
*1 Execute the I/O verification operation by selecting ntlp??? Options
−
Compare with Project from the I/O Table Menu of
the CX-Programmer.
*2 A404.00 to A404.07 contain the error slot number (00 to 09) in binary. “0F hex” indicates that the slot cannot be deter-
mined.
“0B hex” indicates a bus error occurred for the built-in EtherNet/IP port.
“0E hex” indicates the End Cover is not connected to the CPU Rack or an Expansion Rack.
*3 The CJ1W-ID201 (8-point DC Input Unit), CJ1W-OC201 (8-point Contact Output Unit), CJ1W-IA201 (8-point AC Input
Unit), CJ1W-OA201 (8-point Triac Output Unit), and CJ1W-OD201/202/203/204 (8-point Triac Output Units) are allocated
one word each, so set them as 16-point Input Units or 16-point Output Units in the I/O tables when manually setting the
I/O tables from the CX-Programmer. An I/O setting error will occur if they are set as 8-point Input Units or 8-point Output
Units.
*4 Regardless of the error that occurred, the three bits in parentheses will be stored in A407.13 to A407.15. The value will
simultaneously be stored in A407.00 to A407.12.
*5 Bits A410.00 to A410.15 correspond to unit numbers 0 to F.
*6 Bits A411.00 to A416.15 correspond to unit numbers 0 to 95.
Memory Error 0x80F1 A401.15: Mem-
ory Error Flag
A403: Mem-
ory Error
Location
An error has occurred in memory. A
bit in A403 will turn ON to show the
location of the error as listed below.
See below.
A403.00 ON: A checksum error has
occurred in the user program mem-
ory. The power was turned OFF while
storing data to the flash memory
(backup memory).
Check the program and correct the error.
A403.04 ON: A checksum error has
occurred in the PLC Setup.
Clear the entire PLC Setup to 0000 and reenter the
settings.
A403.05 ON: A checksum error has
occurred in the registered I/O tables.
Initialize the registered I/O table and generate a new
I/O table.
A403.07 ON: A checksum error has
occurred in the routing tables.
Initialize the routing tables and reenter the tables.
A403.08 ON: A checksum error has
occurred in the CPU Bus Unit Setup.
Initialize the CPU Bus Unit setup and reenter the
settings.
A403.10 ON: An error occurred in
flash memory (backup memory).
CPU Unit hardware is faulty. Replace the CPU Unit.
Version Error 0x80F2 A401.05: Ver-
sion Error Flag
A293 The user program that was trans-
ferred includes functions that are not
supported by the unit version of the
CPU Unit.
• Check whether the unit version supports the user
program.
• Upgrade the unit version of the CPU Unit.
Card Transfer
Error
0x80F4 A401.03: Mem-
ory Card Error
Flag
--- When A401.03 is ON: The contents
of the Memory Card cannot be cor-
rectly read to the CPU Unit when the
power is ON.
Check whether the files required for executing the
automatic transfer function are available.
System Fail-
ure (FALS)
Error
0xC101 to
0xC2FF
A401.06: FALS
Error Flag
--- FALS(007) has been executed in the
program. The error code in A400 will
indicate the FAL number. The left-
most digit of the code will be C and
the rightmost 3 digits of the code will
be from100 to 2FF hex and will corre-
spond to FAL numbers 001 to 511.
Correct according to cause indicated by the FAL
number (set by user).
