Description
Compares the floating point real number data specified by S1 with the data band specified by S2 and S3,
when the trigger turns on. This instruction checks whether S1 is in the data band between S2 (lower limit) and
S3 (upper limit), larger than S3, or smaller than S2. The comparison result is stored in special internal relays
R900A, R900B, and R900C.
The following table lists the states of the carry flag (R9009), > flag (R900A), = flag (R900B), and < flag
(R900C).
