Diagnosis Function
When errors occur with the CF Reader/Writer, the type of error can be determined through the indicator, i.e.,
by whether the indicator lights red or flashes red.
Errors
The errors detected by the diagnostic function can be classified into two types of errors. One
terminates operation (fatal errors) and the other does not terminate any operation (nonfatal errors).

Fatal Errors
When a CPU error has occurred in the CF Reader/Writer, CPU operation is terminated and the
indicator lights red. The indicator will remain lit red until the power supply is turned OFF. Check the
information in the following table and take appropriate corrective actions before restarting operation.
If the above procedure does not correct the problem, the CF Reader/Writer may be faulty.

between the CF Reader/Writer and Tags, the indicator lights or flashes red. The indicator will turn OFF
after lighting or flashing and the command will be recieved. Check the information in the following table
