Applies only to the display of On, Off and Ax values in a
message text.
Does not apply to the comparison of On and Off values!
(The compare function ignores the decimal point.)
The value of “On”, “Off” and “Dec” can be set/modified in
parameter mode.
Timing diagram
Description of function
The function reads the value of the signal at the analogue
input Ax.
This value is multiplied by the value of parameter A (gain).
Parameter B (offset) is added to the product, hence
(Ax ∙Gain) + Offset = Actual value Ax.
Output Q is set or reset depending on the set threshold
values. See the following calculation rule.
Calculation rule
If threshold (On) ≥ threshold (Off), then:
Q = 1, if the actual value Ax > On
Q = 0, if the actual value Ax ≤Off.
If threshold (On) < threshold (Off), then Q = 1, if
On ≤ the actual value Ax < Off.
NOTICE:
The decimal point setting must be identical in
the min. and max. range.

Analogue Amplifier
Description of function
This SFB amplifies an analogue input value and returns it
at the analogue output.
