7.10 Data control instruction
7.10 Data control instruction
Upper and lower limit control of 16-bit binary data
LIMIT(P)(_U)
These instructions control the output value to be stored in the device specified by (d) by checking the input value (16-bit binary
data) in the device specified by (s3) with the upper and lower limit values specified by (s1) and (s2).
*1 The LIMIT_U instruction is not supported by the ST language. Use LIMIT of the standard function.
