Data Control Instructions
Section 3-18
Description
When the execution condition is ON, LMT(680) controls output data according
to whether or not the specified input data (signed 16-bit binary) is within the
upper and lower limits. The contents of words C and C+1 are as follows:
C and C+1 must have the same area classification.
If the input data (S) is less than the lower limit (C), the lower limit data will be
output to D and the Less Than Flag will turn ON.
If the input data (S) is greater than the upper limit (C+1), the upper limit data
will be output to D and the Greater Than Flag will turn ON.
If the input data (S) is greater than or equal to the lower limit (C) and less than
or equal to the upper limit (C+1), the input data (S) will be output to D.
