Task Error Codes Section 12-4
12-4 Task Error Codes
When a task error occurs, the Error Flag and the Task Error Flag turn ON in
the PLC Interface Area, and a 4-digit error code is output in hexadecimal to
word n+11 (for the MC221) or word n+19 (for the MC421). The following table
shows the address of the Error Flags and the Task Error Flags for both the
MC221 and the MC421.
The meanings of the error codes are explained in the following tables. The
programs referred to here are MC programs written in G language.
Explanation of Tables Under the Code heading, the 4-digit hexadecimal code that is output by the
MC Unit is given first. The number given below it in parentheses is the way it
appears when decimal display is selected at the Programming Console.
Under the
Error name heading, the actual error name is given first and the
name as it appears in the CX-Motion and the Teaching Box is given below it in
parentheses.
000F
(0015) IOWR syntax error
(IOWR SYNTAX ERR) One of the following errors occurred when the IOWR
instruction was executed.
The data address is not within the acceptable range.
The number of transfer data items is not within the
acceptable range.
Example: When rewriting a 4-byte parameter, 8 or 12
bytes were specified.
The number of transfer data items is not in 4-byte units.
Set the correct data and execute the IOWR instruction again.

0010
(0016) IOWR data error
(IOWR DATA ERR) The following error occurred in data to be written to the MC
Unit when the IOWR instruction was executed.
The data is not within the acceptable range.
Set the correct data and executed the IOWR instruction
again.
Deceleration
stop
0011
(0017) Flash memory error
(FLASH MEMORY ERR) Data was not saved in the flash memory.
Save the data in the flash memory again.
The error can be cleared when the data is written normally.
Replace the MC Unit if the error persists.
Deceleration
stop
0012
(0018) EEPROM error
(EEPROM ERR) Data could not be written to the EEPROM, where the error
log is stored.
Perform an error reset, and then continuously operate the MC
Unit. If the error recurs, replace the MC Unit.
Deceleration
