Particular characteristics to be noted when configuring
For help on analog block parameters, refer to the Analog value processing (Page 286)
section.
Analog output
If you connect this special function to a real analog output, then note that the analog output
can only process values from 0 to 1000. To do this, connect an additional amplifier between
the analog output of the special function and the real analog output. With this amplifier you
standardize the output range of the special function to a value range of 0 to 1000.
Example: additional amplifier behind an analog multiplexer.

Analog multiplexer
Short description
When enabled, the analog multiplexer SFB displays one of four pre-defined analog values,
depending on input conditions.
Connection
Description
Input En
1 on input En (Enable) switches, dependent on S1 and S2, a parameterized
analog value to the output AQ.
0 on input EN switches 0 to the output AQ.
0 on input EN switches 0 to the output AQ.
Inputs S1
and S2
and S2
S1 and S2 (selectors) for selecting the analog value to be issued.
S1 = 0 and S2 = 0: The value V1 is issued
S1 = 0 and S2 = 1: The value V2 is issued
S1 = 1 and S2 = 0: The value V3 is issued
S1 = 1 and S2 = 1: The value V4 is issued
Parameter
V1 to V4: Analog values (Value) that will be issued.
Value range: -32768 to +32767
p: Number of decimal places
p: Number of decimal places
Possible settings: 0, 1, 2, 3
