Operands:

: Start device to obtain mean value

: Destination device for storing mean value

: The number of consecutive source devices used

Explanations:

1. After the content of n devices starting from S are added up, the mean value of the result will be

stored in

2. Remainders in the operation will be left out.

3. Provided the No. of designated device exceeds its normal range, only the No. within the normal

range can be processed.

4. If

n falls without the range of 1 ~ 64, DOP-EXIO series will determine it as an “instruction

operation error”.

Program Example:

When X10 = On, the contents in 3 (n = 3) registers starting from D0 will be summed and then divided

by 3. The obtained mean value will be stored in D10 and the remainder will be left out.
