Upper And Lower Limit Control Of 32-Bit Binary Data - Mitsubishi Electric MELSEC iQ-F FX5 Programming Manual

Upper and lower limit control of 32-bit binary data

DLIMIT(P)(_U)
These instructions control the output value to be stored in the device specified by (d) by checking the input value (32-bit binary
data) in the device specified by (s3) with the upper and lower limit values specified by (s1) and (s2).
