Calculation of averages for 16-bit data, calculation of averages
for 32-bit data
MEAN(P), DMEAN(P)
Processing details
■MEAN(P)
• This instruction calculates the mean of 16-bit BIN data stored in n-point devices starting from the device specified by (S),
and then stores the result into the device specified by (D).
• If the value calculated is not integer, this instruction will drop the number of decimal places.
• If the value specified by n is 0, the instruction will be not processed.
■DMEAN(P)
• This instruction calculates the mean of 32-bit BIN data stored in n-point devices starting from the device specified by (S),
and then stores the result into the device specified by (D).
• If the value calculated is not integer, this instruction will drop the number of decimal places.
• If the value specified by n is 0, the instruction will be not processed.
• QnU(D)(H)CPU, QnUDE(H)CPU: the serial number (first five digits) is "10102" or later
• Q00UJCPU, Q00UCPU, Q01UCPU, QnUDVCPU: Supported
(S): Head number of the devices where the data to be averaged are stored (BIN16/32 bits)
(D): 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) (BIN 16 bits)
