Processing details
■Range check
This function block checks the range of an input value.
High limit range error (HH)
High limit range error reset (H_)
Input value
Low limit range error reset (L_)
Low limit range error (LL)
No. Condition
Input value  HH
(1)
Input value  H_
(2)
Input value  LL
(3)
Input value  L_
(4)
HH: High limit range error
H_: High limit range error reset
LL: Low limit range error
L_: Low limit range error reset
■Input limiter
This function block performs input limiter processing.
Input limiter processing result
NMAX
NMIN
NMIN
Operation when input limiter processing is enabled.
Condition
Input value  NMAX
Input value  NMIN
NMIN < Input value < NMAX
NMAX: Input high limit, NMIN: Input low limit
