7 APPLICATION INSTRUCTIONS
7.9 Real Number Instructions
■Applicable devices
*1 T, ST, and C cannot be used.
Processing details
• These instructions compare the band between the single-precision real number specified by lower limit value (s1) and the
single-precision real number specified by upper limit value (s2) with the single-precision real number in the device specified
by comparison data (s3). According to the comparison result (below, within zone, or above), (d), (d)+1, or (d)+2 is turned
on.
Precautions
• Set (s1) to a value less than (s2). If (s1) is set to a value greater than (s2), (s2) is treated as the same value as (s1).
