Perform the following procedures to erase the error display.
(a)
When the basic unit is being stopped
Turn the basic unit RUN switch (or RUN terminal) to “STOP,” then to “RUN” again.
If the cause of the error has been corrected, the OK lamp is lit. However, the error information remains in the
error special internal output, which stores the CPU error types and details. (This makes it possible to analyze
the error after recovery.) To reset the error information, perform the procedures shown in (b) or turn ON the
special internal output (R7EB) of the power failure memory clear on the peripheral units.
(b)
When the CPU is still running (RUN)
Set the special internal output R7EC to “1” to clear the OK lamp indicator and the error internal output.
