Limitation elements

Purpose
The controller provides two limitation elements. With these function blocks signals
can be limited to adjustable value ranges.
Parameter setting
FIG 7-35
FIG 7-36
1. Input
With the function "freely assignable analog inputs" each input can be assigned to
a "terminal signal" from the table in C145.
2. Outputs
With the function "freely assignable analog inputs" the outputs can be assigned to
the targets listed under C146.
3. Function
The function is an override function. If the input signal exceeds the upper limit
(C630 or C635), the upper limit is effective. If the input signal falls below the lower
limit (C631 or 636), the lower limit is effective.
