8.2 Troubleshooting
Error code is 20 or higher
Condition
A self-diagnostic error other than a syntax error has occurred.
Operation
Use the programming tool in PROG. mode to clear the error.
Using programming tool software (FPWIN GR)
Click "Clear Error" button in the "Status Display" menu described on the previous page.
Error code 43 and higher can be cleared.
In the PROG. mode, the power supply can be turned off and then on again to clear the
error, but all of the contents of the operation memory except hold type data are cleared.
An error can also be cleared by executing a self-diagnostic error set instruction F148
(ERR)/P148 (PERR).
When an operation error (error code 45) occurs, the address at which the error occurred
is stored in special data registers DT90017 and DT90018. If this happens, monitor the
address at which the error occurred before cancelling the error.
