Calculating The Mean Value Of 32-Bit Binary Data - Mitsubishi Electric MELSEC iQ-R Series Programming Manual

Calculating the mean value of 32-bit binary data

DMEAN(_U)
These instructions calculate the average value of the (n) points of 32-bit data in the devices starting from the specified one.

Processing details
• These instructions calculate the average value of the (n) points of 32-bit binary data in the devices starting from the one
specified by (s), and stores the average value in the device specified by (d).
(s)+1, (s)
(s)+3, (s)+2
(s)+2(n)-1, (s)+2(n)-2
(1) Mean value
• If the calculation result is not an integer, the first decimal place is rounded down.
• When (n) is 0, the processing is not performed.
Operation error
There is no operation error.
