1
Turn ON the STEP signal while the BUSY signal is OFF.
2
Measurement begins and the BUSY signal is turned ON during the measurement process.
3
Measurement data is output when a Parallel Data Output Unit in the measurement flow is executed.
4
After the data output processing, the GATE signal is turned ON after the time set for the [Gate
ON delay] in the parallel communications settings has elapsed.
*1: A delay of up to 1 ms will occur when the GATE signal is turned ON. (This applied only to the FH.)
5
After the GATE signal is turned ON, the GATE signal is turned OFF after the time set for the
[Output time] in the parallel communications settings has elapsed.
6
If the processing for the next data item is completed, the next GATE signal is turned ON after
the time set for the [Output period] has elapsed from the end of processing in step 5 above.
*2: Set the GATE ON delay and output time for the GATE signal so that the total time does not exceed the output period.
7
After measurement is completed, the OR signal is output based on the measurement result
and the BUSY signal is turned OFF.
IMPORTANT
Data Output Time and STEP Signal Input Interval
Set the input interval for the STEP signal so that it is longer than the total output time. If the STEP signal input
interval is shorter than the total output time, the data output buffer will eventually overflow and data will be lost.
