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, the 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 I/O Unit is
mean value processing with 2 buffers. If the mean value function is used,
