Mode of Operation

The G38910051 is a Dupline

to Lonworks gateway with
built-in channelgenerator. The
module, based on FTT-10A
transmission media, makes
Dupline

digital and analink

inputs directly available as
standard Lonmark network
variables. Also, it is possible to
control Dupline

digital and

analink signals using network
variables. In total, the module
offers 242 input variables and
242 output variables. Several
Dupline

gateways can be

connected to the same
Lonworks network.

Dupline Configuration
switches
The unit is equipped with the
following Dupline

configuration

switches. (See also switch
settings)

1x16 position rotary-switch for
selecting Number of Dupline

Channels in the range 8..128 (in
steps of 8). The selected letter
indicates the last channel group
available on Dupline

. If e.g. H

is selected, the 64 channels in
groups A..H will be available.

DIP-switch (1) for selection of
Dupline

Operation Mode. In

"Normal" mode, Dupline

operates as a peer-to-peer

system where the channel
generator automatically estab-
lishes a connection between
Dupline

inputs and Dupline

outputs which are coded to the
same Dupline

address. If e.g.

an input coded for B5 is
activated, the output(s) coded
for B5 will also be activated.
Consequently a Dupline

output

can either be activated through
the corresponding Lonworks
network variable or by an active
Dupline

input coded for the

same Dupline

address. In

"Split I/O" mode, the Dupline

inputs and Dupline

outputs are

created independently by the
channel generator. If e.g. an
input coded for B5 is activated,
the Gateway will propagate the
event via the associated
Lonmark network variable (like
in normal mode), but it will not
automatically activate the
Dupline

output(s) coded to B5.

In "Split I/O" mode, the
Dupline

outputs are controlled

exclusively through the Lonmark
network variables.

DIP-switch (2), DIP-switch (3)
and DIP-switch (4) are not used
in this module.

The Service-pin, located on the
front of the module on the right-
hand side, can be used

during commissioning and
maintenance. When activated,
the G38910051 sends a
Lonworks service message
containing its 48-bit unique ID
on the network. This information
can be used by a network
management tool (e.g.
Lonmaker) to install and
configure the node.

Dupline

Input Data

A part of the Gateway input
processor reads all the 128
Dupline

-channels as Digital

inputs and another part reads
the 112 channels (C1 to P8) as
Analink inputs. Each Dupline

digital input has a Lonmark
network variable of type
SNVT_switch assigned to it.
It is also possible to read
the status of the Dupline

digital input by using the vari-
ables nvo_state_64_AH and
nvo_state_64_IP, which are of
the type SNVT_state_64. Each
of these variables contains the
status of 64 Dupline

channels

(A1-H8, I1-P8) and they are
effective in use when a Lon-
works device needs to read the
status of several Dupline

channels.
There is also a Lonmark
network variable assigned to
each Dupline

analink input in

the range C1-P8. It has been
chosen to make two commonly
used variable types available,
namely SNVT_temp_p (channels
C1-I8) and SNVT_lev_percent
(J1-P8). So temperature
sensors need to be assigned an
address in the range C1-I8, and
analink devices with 0-20 mA,
4-20 mA or 0-10 VDC inputs
must be assigned an address in
the range J1-P8. Also, in order
to achieve the correct scaling
for an Analink temperature
sensor, it is necessary to use
the G89111010 or G86111010,
which both operate in the range
30 to +60 C. See table
"Lonwork network variables for
further information".

Dupline

Output Data

There are 128 network variables
of type SNVT_switch available
for control of the digital status
of each Dupline

channel. It is

also possible to perform the
control by using the network
variables nvi_state_64_AH (cov-
ering A1-H8) or nvi_state_64_IP
(covering I1-P8), which are of
the type SNVT_state_64. These
are effective in use if one Lon-
work node need to control sev-
eral Dupline

channels. If Nor-

mal mode is selected on DIP-
switch (1), the outputs can also
be controlled from Dupline

transmitters coded for the
same address as the output
(OR-function).
For control of Dupline

analog

outputs, there are 112 network
variables of type SNVT_lev_

percent available, one for each
channel in the range C1-P8). If
e.g. the value 50% is sent to
such a variable, the output of a
4-20mA Dupline

module with

this address will be 12 mA.

The Neuron chip ID is printed
