Upper and lower limit control of 32-bit binary data
DLIMIT(P)(_U)
These instructions control the output value depending on whether the specified 32-bit binary bit value is within the upper and
lower limits.
*1 The DLIMIT and DLIMIT_U instructions do not support the ST and FBD/LD. Use the standard function, LIMIT.
