: 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) (BIN 16 bits)
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.
Operation Error
(1) In any of the following cases, an operation error occurs, the error flag (SM0) turns on, and an error code is stored into
SD0.
