5 OPERATION CONTROL PROGRAMS
[Functions]
(1) Conversion of the input value specified with (S2) is executed according to the
search/conversion method specified with (S1), using the scaling conversion data
of device (S3) or later. The conversion result is stored in the device specified with
(D).
(2) The setting method of (S1) is the same as 16-bit integer type scaling. (Refer to
Section 5.16.1.)
(3) The device No. specified with (S3) should be an even number. Set the point data
in the specified device as follows.
