12-1 Indicators and the Error Log
When an error occurs in the CPU bus, Ethernet network, or other parts of the
system, the PC Card Unit indicates the error with indicators and records it in the
error log to enable the user to identify the error. This section explains how to
retrieve the records in the error log and describes the error log and indicators.
Note Turning the PC Card Unit OFF erases the error log. To prevent this, always
retrieve the error log before turning the PC Card Unit OFF.
12-1-1 Reading the Error Log
To read the error log, execute the FINS command ERROR LOG READ (com-
mand code 21 02) from another computer or CV-series CPU, addressing it to the
PC Card Unit.
Refer to ERROR LOG READ in 11-2 PC Card Unit Commands and Responses
for details on command usage and response details.
12-1-2 Error Log and Indicators
The following table describes the error types and codes recorded by the PC
Card Unit. It also shows the ON/OFF status of each indicator on the front panel of
the PC Card Unit when the error occurs.
