EX_OK/EX33_OK
Three modes of output are available for EX_OK. The presence or absence of the output and the mode switching of the
output are performed in C-Flash (see below).
① Result output (High at OK, Low at NG)
Hi is output when write completes successfully. If writing fails, nothing(L) is output.
② LED interlocking (Pulse output during writing, High at OK, Low at NG)
EX_OK pulse will resemble the turning on and off of the STS LED on the FP.
The following waveform is output during Write operation and when the operation completes successfully:
The following waveform is output during Write operation and when the Write operation fails:
*1 : Low/Hi signal period may vary during Write operation
③ Write interlocking (High during writing, Low after writing)
Hi is output on EX_OK when Write operation is in progess. After write operation comepletes, irrespective of
whether the Write operation succeeds or fails the signal level drops to L.
