S: This function is supported only in FX3U/FX3UC PLCs.
Explanation of function and operation
1. 16-bit operation (SER and SERP)
In "n" data starting from , same data as is searched, and the search result is stored to to
+4.
1) Contents of searched data and the search result
a) When same data was detected
Five devices starting from store the number of same data, first position, last position, maximum value
position and minimum value position.
b) When same data was not detected
Five devices starting from store the number of same data, first position, last position, maximum value
position and minimum value position.
In this case, however, "0" is stored in three devices starting from (which store the number of same
data, first position and last position).
