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

Upper and lower limit control of 32-bit binary data

DLIMIT(P)(_U)
RnPCPU RnPCPU
RnCPU RnENCPU
(Process) (Redundant)
These instructions control the output value depending on whether the specified 32-bit binary bit value is within the upper and
lower limits.
