Operands:
S: Source device D: Destination for storing result n: Number of consecutive device from S
Explanations:
1. The instruction obtains the mean value from n consecutive registers from S and stores the
value in D.
2. Remainders in the operation will be ignored.
3. If S is not within the valid range, only those addresses within the valid range will be processed.
4. If n is out of the valid range (1~64), PLC will determine it as an “instruction operation error”.
5. If operand D uses index F, only a 16-bit instruction is available.
6. Valid range of operand n : n = 1~64
Program Example:
When X10 = ON, the contents in 3 (n = 3) registers starting from D0 will be summed and then
divided by 3 to obtain the mean value. The result will be stored in D10 and the remainder will be
left out
