4.4.26 Analog Multiplexer

Short description
This special function outputs one of four predefined analog
values or 0 at the analog output.
Symbol in IDEC
SmartRelay
Parameters V1...V4
The analog values for the parameters V1...V4 can be
derived from another already-programmed function. You can
use the actual values of the following functions:
• Analog comparator (actual value Ax - Ay, see Chapter
4.4.18)
• Analog trigger (actual value Ax, see Chapter 4.4.16)
• Analog amplifier (actual value Ax, see Chapter 4.4.20)
• Analog multiplexer (actual value AQ)
• Analog ramp control (actual value AQ, see Chapter
4.4.27)
• Analog math (actual value AQ, see Chapter 4.4.30)
• PI controller (actual value AQ, see Chapter 4.4.28)
• Up/down counter (actual value Cnt, see Chapter 4.4.13)
Select the required function by the block number. For
information on parameter defaults, refer to Chapter 4.4.1.

Input En A change in status from 0 to 1 at input
En (Enable) switches a parameterized
analog value to the output AQ,
depending on the value of S1 and S2.
Inputs S1 S1 and S2 (selectors) for selecting the
analog value to be issued.
and S2
• S1 = 0 and S2 = 0: 
Value 1 is issued
• S1 = 0 and S2 = 1: 
Value 2 is issued
• S1 = 1 and S2 = 0: 
Value 3 is issued
• S1 = 1 and S2 = 1: 
Value 4 is issued
Parameter V1...V4: Analog values that will be
issued.
Range of values: -32768...+32767
p: Number of decimals
Range of values: 0, 1, 2, 3
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:
-32768...+32767
