10.15 LIMT (Upper and Lower Limit Control)
(Note 8) Can be specified only when the operation unit is a double-precision floating point real number (DF).

Outline of operation
● The output value, to be stored in the device address specified by [D], is controlled based on
whether or not the input value specified by [S3] falls within the range bounded by the upper
and lower limits set in [S1] and [S2].
● Output values are defined as follows:
Lower limit [S1] > Input value [S3]
Upper limit [S2] < Input value [S3]
Lower limit [S1] ≤ Input value [S3] ≤ Upper limit [S2]
● For control by the upper limit only, the minimum value for the relevant operation unit is
specified as the lower limit [S1].
● For control by the lower limit only, the maximum value for the relevant operation unit is
specified as the upper limit [S1].
