L Data Processing Timing - Omron CQM1H series Operation Manual

Sampling
The Unit processes input data in the following two blocks.
• A:
Input sampling time = Sampling period x No. of mean value processings
• B:
Operation process and data set to the data input word
The Unit has the following two sampling periods.
• Fast:
1 ms (with 0.3-ms sampling time)
• Slow:
2 ms (with 0.6-ms sampling time)
The necessity of the sampling hold process depends on the timing hold.
Sampling Example
The following are typical sampling timing examples.
Example 1 Timing Hold:
No. of Mean Value Processings: 1
Input Sampling Speed:
Example 2 Timing Hold:
No. of Mean Value Processings: 4
Input Sampling Speed:
