•
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.
8.1.2 Operation on Error
•
Normally, when an error occurs, the operation stops.
•
The user may select wheter operation is to be continued or stopped when a duplicated output error or
operation error occurs, by setting the system registers. You can set the error which operation is to be
continued or stopped using the programming toolshoftware as shown below.
“PLC System Register” setting menue 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.
