4.4.20 Analog amplifier
Short description
This special function amplifies the value of an analog input
and outputs the result at an analog output.
Gain and offset parameters
Please note the information on gain and offset parameters in
Chapter 4.3.6.
Parameter p (number of decimals)
Applies only to the AQ value in a message text.
Functional description
The function fetches the analog signal of input Ax.
This value is multiplied by the value of the A (gain)
parameter, and parameter B (offset) is then added to the
product: (Ax•gain) + offset = actual value Ax.
The actual value Ax is output at AQ.

Description
Input Ax
You apply the analog signal to be
amplified at input Ax.
Use the analog inputs AI1...AI8
(
*
)
, the
analog memory markers AM1...AM6,
the block number of a function with
analog output, or the analog outputs
AQ1 and AQ2.
Parameter
A: Gain
Range of values:
10.00
B: Zero offset
Range of values:
10,000
p: Number of decimals

Output AQ This special function has an analog
output! This output can only be
connected with the analog input of a
function, an analog memory marker or
an analog output connector (AQ1,
AQ2).
Range of values for AQ:
-32767...+32767
