Data Output Timing
●
Output Sequence
If both parallel judgement output and parallel data output are performed at the same time, parallel judgement
output will be performed first followed by parallel data output.
Example: Parallel Judgement Output of D0 to D15 and Parallel Data Output of Data 0
●
Timing Chart
The following timing chart shows the data output timing for parallel judgement outputs.
The data that is output to the OR and D signals after a measurement is held until the next measurement is per-
formed. The values will continue to be output even after all measurements have been completed.
However, if you set the output timing of the OR signal to [One-shot output] in the [Output mode] parameter, the OR
signal will turn OFF after the specified output time has elapsed.
