1,2,3... 1. With the first cycle, Data 1 is stored in all the history buffers.
Mean value = (Data 1 + Data 1 + Data 1 + Data 1)
÷ 4
2. With the second cycle, Data 2 is stored in the first history buffer.
Mean value = (Data 2 + Data 1 + Data 1 + Data 1)
÷ 4
3. With the third cycle, Data 3 is stored in the first history buffer.
Mean value = (Data 3 + Data 2 + Data 1 + Data 1)
÷ 4
4. With the fourth cycle, Data 4 is stored in the first history buffer.
Mean value = (Data 4 + Data 3 + Data 2 + Data 1)
÷ 4
5. With the fifth cycle, Data 5 is stored in the first history buffer.
Mean value = (Data 5 + Data 4 + Data 3 + Data 2)
÷ 4
When a disconnection is restored, the mean value processing function begins
again from step 1.
Note 1. The default setting for mean value processing in the Analog Input Unit is
mean value processing with 2 buffers. The response time for the default
