Data Processing Timing
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
Data processing Next data processing
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: Normal
No. of Mean Value Processings: 1
Input Sampling Speed:
Fast
Example 2 Timing Hold: Sampling hold
No. of Mean Value Processings: 4
Input Sampling Speed:
Fast
Timing input
