(1) Searches n points from the 16-bit data of the device designated by (S2), regarding
16-bit data of the device designated by (S1) as a keyword. Then, the number of
matches with the keyword is stored at the device designated by (D)+1, and the
first matched device number (in the relative number from (S2)) is stored at the
device designated by (D).
(2) No processing is conducted if n is 0 or a negative value.
(3) If no matches are found in the search, the devices designated at (D) and (D)+1
become "0".
The range of n exceeds that of the device specified in (S2) or the points specified in n
exceed those of the corresponding device specified in (D), sequence program error
occurs.
Safety observation warnings (SM24) are turned ON and error code (SD32): 10, detail
code (SD33): 8014H are stored.
