Function
MEAN(P)
(1) This instruction calculates the mean of 16-bit BIN data stored in n-point devices starting from
the device specified by
(2) If the value calculated is not integer, this instruction will drop the number of decimal places.
(3) If the value specified by n is 0, the instruction will be not processed.
DMEAN(P)
(1) This instruction calculates the mean of 32-bit BIN data stored in n-point devices starting from
the device specified by
S ＋1,
S ＋3,
＋2n−1,
S
(2) If the value calculated is not integer, this instruction will drop the number of decimal places.
(3) If the value specified by n is 0, the instruction will be not processed.
