2.6. Counter and Multiplexer

2.6.1. Multiplexer (transmission of counter values)

Description
The counter channels with the sum sign ∑ are for transmission of counter values. This multiplex transmission
of up to 128 counter values is dedicated to the use of the counter module G 4420 7401.
The range of values to be transmitted can be selected in the Basic setup through the option "Counter range".
Depending on the range of values, a corresponding number of address groups are reserved, whereby the
Multiplex system is started.
Hint: The reserved addresses must not be used for other purposes, eg to output switch commands.
There are no further configuration possibilities in the Configuration software - addressing of the channels as
well as transmission and saving of data is carried out automatically by the Master Generator.
Module configuration
Detection of the counter values requires correct setting of the counter module G 4420 7401. Apart from the
setting the counter range, it is also necessary to assign an address to each module through rotary switch.
Data format
A description of the used data format can be found in the user manual of the counter module G 4420 7401.
Counter value output
Access to and output of the stored counter values is only done through the Modbus communication interface
of the Master Generator. There are basically 3 possibilities of continued processing:
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
3. Individual reset of counter values.
Simultaneous operation with Multiplex Analog Value Transmisison
If transmission of counter and analog values is needed, 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 transmission. Read the following chapter 2.6.2. "Multiplexer (Transmission of analog values)".
