12-4 Task Error Codes
Explanation of Tables
536
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.
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.
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.
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.
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.

Task Error Flag Task 1
Task 2
Task 3
Task 4
The meanings of the error codes are explained in the following tables. The
programs referred to here are MC programs written in G language.
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.
