2. 32-bit operation (DLIMIT/DLIMITP)
Depending on how the input value (32-bit binary value) of the device specified by compares to the range
between the upper and lower limits specified by and , the output value to be stored in the device
specified by is controlled.
Error
An operation error is caused when the instruction is executed in the setting status shown below. The error flag
M8067 turns ON, and the error code (K6706) is stored in D8067.
