8.12
Data Control Instruction
Upper and lower limit control of 16-bit binary data
LIMIT(P)(_U)
These instructions control the output value to be stored in the device specified by (d) by checking the input value (16-bit binary
data) in the device specified by (s3) with the upper and lower limit values specified by (s1) and (s2).
*1 The LIMIT and LIMIT_U instructions are not supported by the ST language and the FBD/LD language. Use LIMIT of the standard
function.
