MEAN(P),DMEAN(P)
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 , 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.
DMEAN(P)
(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.
: Head number of the devices where the data to be averaged are stored (BIN16/32 bits)
: Head number of the devices where the average will be stored (BIN 16/32 bits)
n : Number of data or number of the devices where the number of data are stored(Setting range: 1 to 32767)
