7 APPLICATION INSTRUCTION
7.10 Data control instruction
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).
*1 The DLIMIT(_U) instructions are not supported by the ST language. Use LIMIT of the standard function.

Processing details
• 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). The output value
is controlled as follows.
• To control the input value only with the upper limit, set the minimum value within the setting range in (s1).
• To control the input value only with the lower limit, set the maximum value within the setting range in (s2).
