Processing of analog values
As opposed to the counter values, it is not only possible to visualize the analog multiplex values through the
Modbus communication interface, but also to change them. There are basically two possibilities of value pro-
cessing:
1. Representing the values in visualization software or operator panel (eg on a PC with the Dupline Web-
Server).
2. Through communication programmes, eg the Dupline DDEServer - an open software interface to for
example Microsoft
Simultaneous operation with transmission of multiplex analog values
If both multiplex modes are used, care should be taken to avoid address overlap. The transmission channels
of the analog modules must be set so that they do not overlap the channels of the counter value transmis-
sion. Read the preceding chapter 2.6.1. "Multiplexer (Transmission of counter values)".
Working with test unit GTU8
GTU8 makes it easy to read out and simulate analog values of this format (operation mode Analog BCD). In
the case of simulation, care should be taken that both the bit "Signal available" and the validity bit have been
set (see above).

Description
With this setting made under <Edit><Counter & Mux Analog Setup>, you select
how many modules should be addressed. The number depends on the number
of applied modules and their in-/output channels. From 0 to 16 addresses can
be selected. The value 0 switches the multiplex operation out.
With this setting made under <Edit><Counter & Mux Analog Setup>, you select
how fast the Master Generator may scan the multiplex addresses. This setting
only has an effect when multiplex transmission has been activated (at least 1
multiplex channel selected).
Since some of the Dupline Multiplex modules need a large part of their capacity
for internal processing, their response time is reduced. This can be balanced by
a longer delay. The Master Generator then waits for the corresponding number of
cycles between the scans.
