DescriptionWiring
Output AQ This special function has an
analog output
(= manipulated variable)!
This output can only be con-
nected with the analog input
of a function, an analog flag
or an analog output
connector (AQ1, AQ2).
Range of values for AQ:
0...1000
Parameters SP, Mq
The analog values for the parameters SP and Mq 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 threshold trigger (actual value Ax, see Chapter
4.4.16)
 Analog amplifier (actual value Ax, see Chapter 4.4.20)
 Analog multiplexer (actual value AQ, see Chapter
4.4.26)
 Analog ramp (actual value AQ, see Chapter 4.4.27)
 PI controller (actual value AQ)
and
 Up/down counter (actual value Cnt, see Chapter
4.4.13).).
Select the required function by means of the block number.
For information on parameter defaults,
refer to Chapter 4.4.1.
