How to troubleshoot flashing ERROR/ALARM LED on NAiS FP?
If the ERROR/ALARM LED is flashing on your NAiS Controller, it indicates a self-diagnostic error. Use the programming tool to check the specific error code. Alternatively, in ONLINE mode, select 'STATUS DISPLAY' to find the error code at the bottom of the 'STATUS DISPLAY' window.
What to do if NAiS FP Controller error code is 20 or higher?
If your NAiS Controller displays an error code of 20 or higher, it signifies a self-diagnostic error other than a syntax error. You can try the following: * Use the programming tool in PROG. mode to clear the error. * Press the ** key in the status display menu. * Click the 'Clear Error' button in the status display menu. * Navigate to Monitor –> PLC Status –> Click Clear. In PROG. mode, turning the power OFF and then ON again may clear the error, but all operation memory contents (except hold type data) will be cleared. You can also clear the error by executing a self-diagnostic error set instruction F148 (ERR).
How to fix syntax error in NAiS FP Controller program?
If there is a syntax error in the program of your NAiS Controller, change to PROG. mode and clear the error. You can also execute a total-check function to determine the exact location of the syntax error.
