LE—Less Than or Equal To
The LE function block sets OUT to TRUE if IN1 is lesser than or equal to IN2.
OUT = TRUE IF IN1 ≤ IN2
LIMIT—Limit Function
The LIMIT function block will limit IN within the data range specified by the minimum limit,
MN and the maximum limit MX. The range limited input is written to OUT. OUT will only
be updated if MX ≥ MN.
OUT = IN IF MN ≤ IN ≤ MX
OUT = MN IF IN < MN
OUT = MX IF IN > MX
