4.4.26 Analog Multiplexer

Short description

This special function outputs one of four predefined analog

values or 0 at the analog output.

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.

Description

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
and S2

S1 and S2 (selectors) for selecting the

analog value to be issued.

• 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
