• The control unit has a self-diagnostic function which
identifies errors and stops operation if necessary.
• When an error occurs, the status of the status indicator
LEDs on the control unit vary, as shown in the table above.

11.1.2 Operation Mode When an Error Occurs

Normally, when an error occurs, the operation stops.
When the duplicated output error or operation error occurs, the user may select whether operation is to
be continued or stopped by setting the system registers. You can set the error which operation is to be
continued or stopped using the programming tool software as shown below.
"PLC System Register" setting menu on programming tool software
To specify the steps to be taken by the FPWIN GR if a PLC error occurs, select "PLC System Register
setting" under "Option" on the menu bar, and click on the "Action on Error" tab. The screen shown below
is displayed.
Example1: When allowing duplicated output
Turn off the check box for No. 20. When operation is resumed, it will not be handled as an error.
Example2: When continuing operation even a calculation error has occurred
Turn off the check box for No. 26. When operation is resumed, it will be continued, but will be handled as
an error.
