Product Description
Ordering Key
The Counter enables impulse
counting on up to 4 channels
or entry of up to 4 periods of
operation with cyclic transfer
on the Dupline
Bus.
The device has DIP-switches
for operating mode, for reset
of counter via Dupline
and
for selection of measuring
range with 2 to 8 decades.
The Two rotary switches
enable individual assignment
of device address.
The counter readings can be
displayed on a Touch Screen
panel or by means of visual-
ization software.
Upon voltage failure, the
counter values will be stored
and be available after return
of the voltage.

In order to avoid disturbances, the length of the cable between the counter inputs of G4420 7401 and the impulse output
should not exceed 5 m. NOTE: The G4420 7401 724 is pure DC-supplied. The G4420 7401 230 are having the possibility
of two powersupplies. Both a DC and a AC, If using the DC Supply, the minus of the supply is used as common wire
for the inputs of the module.

Dupline
is a registered trademark. A product of the CARLO GAVAZZI Group
G4420 7401 has 4 DIP-switches for selection of Operating
mode and 2 rotary switches for selection of device address.
Selection of device address (rotary switches)
Selection of device address is performed by means of the two
rotary switches at the front. In multiplex mode, up to 32 devices
with 4 channels each (128 counter values) can operate on the
same Dupline
network simultaneously.
The address selection is deliberately kept simple: all that is
needed is to assign a unique address to the first of the four
channels of G 4420 7401. The following addresses are then
automatically assigned to the three other channels. If several
G 4420 7401 are used, the settings must look as follows:
The 4 counter inputs can be selected individually as follows:
A change of address during operation has immediate effect,
but does not influence the counter value. After the change, the
G 4420 7401 transmits updated values to the new address.
The Dupline
multiplex operation makes it possible to transmit
several counter or analog values to the same address so that
the number of addresses in use remains relatively low. By
means of a special addressing mechanism, it is possible to
transmit up to 128 signals on channels B2 to B8.
If a device detects the address of one of its channels, it will
transfer the data to the bus in the same cycle. The addresses
used for counting start with C1 and depending on the mea-
suring range go up to F8. The address is created as a binary
value.
RESET Feature (Dip-switch 1)
The G 4420 7401 makes it possible to reset each of the four
counter values induvidually via the Dupline-Bus. In order to
prevent unwanted resetting, this function can be disabled for all
channels via Dip-Switch 1.
Dip-switch 1 OFF: Reset Disabled
Dip-switch 1 ON: Reset Enabled
The Reset of a value takes place through address B1. If the
address is set to "1" during the reading of the value, the G 4420
7401 automatically sets the counter value to "0". It is also pos-
sible to reset the respective multiplex address by setting B1 to
"1" and then back to "0".
Operating Mode (DIP switch 2)
It is possible to select operating mode for all channels with DIP
switch 2. Two modes can be selected:
Dip-switch 2 OFF: All channels operates as impulse Count
Dip-switch 2 ON: All channels operates as impulse Count or
ON-time Summarizing
When operating as an impulse counter (position "OFF"), the
G 4420 7401 counts impulses at the inputs of up to 20 Hz.
When DIP switch 2 is set to "ON", G 4420 7401 counts the
operating hours and sums up the time for which the contact
connected to the input is enabled. Min. time is 1 s.
Selection of measuring range DIP switches 3 & 4
DIP switches 3 & 4 make it possible to select measuring ranges
with 2 to 8 digit positions in two steps. If the measuring range
is exceeded, the counter rolls over and starts from zero.
Data channels
Data transmission by G 4420 7401 always starts on the first
address in channel group C. The number of addresses needed
depends on the selected measuring range. The value "59" lies
in the range from 0 99 and looks as follows:
The value " 7584" lies in the range from 0 9999 and looks as
follows:
