Calculation of averages for 16-bit or 32-bit data 

(MEAN(P),DMEAN(P))

MEAN(P),DMEAN(P)

Function

(1) This instruction calculates the mean of 16-bit BIN data stored in n-point devices starting from 

the device specified by 

, and then stores the result into 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.

(1) This instruction calculates the mean of 32-bit BIN data stored in n-point devices starting from 

the device specified by 

, and then stores the result into 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.

• QnU(D)(H)CPU: The serial number (first five digits) is "10102" or later.
• QnUDE(H)CPU: The serial number (first five digits) is "10102" or later.
