1 Notes for the planning engineer
1.1 Overview
The @Link option allows the integration of Nordmann AT4 humidiers into
a BACnet/IP or a LonWorks network. The @Link option features a serial-
interface Gateway which converts the information from the host Modbus
protocol to a specied secondary protocol.
The following protocol options are available and must be specied when
ordering (ordering form see page 23):
Part Number Protocols Part Description
2559069 BACnet/IP BMS AT4 Master set for BACnet /IP
2559070 LonWorks BMS AT4 Master set for LonWorks
2559071 BMS AT4 Slave set for successive units
The following read out and settings functions are available:
Functions AT4
Read out of unit status (operating mode, etc.) X
Read out of service messages X
Read out of analog (%) and sensor (%rh) demand X
Read out of unit type X
Read out actual system request X

1.2 Network diagrams
It is possible to link up a maximum of 8 units via a single ProtoCessor
Gateway to a building management system. The ProtoCessor Gateway is
connected to the lead unit. All other units (up to a maximum of 8) are daisy-
chained via the NetworkLink terminals.
Since each unit can be separately addressed, it is possible to monitor and
control each unit individually. Different network congurations may be achieved
and are mostly dependant on the type of network present at the site.

1.2.1 BACnet/IP network
The diagram below shows the connection of a series of Nordmann AT4
units to an Ethernet network. This is only possible for BACnet and is es-
sentially referred to as a BACnet/IP conguration. Please see chapter 2.1
for additional details.

2 Wiring
The internal wiring and the installation of the Gateway option in the lead-
ing unit as well as the internal wiring of the successive units are made at
the factory. On site only the gateway must be connected to the network
(BACnet/IP or LonWorks) and the successive units must be daisy-chained
via the NetworkLink terminals using two-wire cables (see corresponding
wiring diagrams).

Important: make sure the Modbus address for each unit is unique!
Parity: None1 (no parity, 1 Stop bit)
The following Modbus parameters of the Nordmann AT4 can not be adjusted and are set to the follow-
ing values:
– 9600 baud
– 1 start bit
– 8 data bits
2. Select the signal source

3.2 Gatewayconguration
The protocol conguration is made at the factory, prior to nal testing.
The baud rates are adjusted to the following values:
Protocol Baud rate
BACnet/IP 10 / 100 BaseT
LonWorks 78125 bps
3.2.1 SettingtheIPaddressandsubnetmask
For BACnet/IP and LonWorks application, an IP address and the subnet
mask must be assigned to the gateway in order to access it. The IP ad-
dress and subnet mask may be assigned at the factory or can be modied
at any time via the integrated FieldServer GUI (Graphic User Interface) of
the ProtoCessor.
To congure the IP address and the subnet mask via the integrated Field-
Server GUI of the ProtoCessor proceed as follows:
1. Connect the ProtoCessor gateway to a PC using an Ethernet cross-
over cable or directly to the network using a straight cable.
2. The default IPaddress of the ProtoCessor Gateway is set to 10.232.72.172,
Subnet Mask is 255.255.0.0.
Make sure your PCis in the same IP network as the ProtoCessor Gate-
way; otherwise assign a static IP address to your PCon the 10.232.72.0
network.
3. Power up the ProtoCessor Gateway.
4. Open your internet browser and enter the IP address of the gateway
(by default ex factory 10.232.72.172), then conrm the entry with the
Enter key.

10
5. The FieldServer GUI will be started.
6. Select the menu point “Setup > Network Settings” in the “Navigation
Tree”. Enter the appropriate IP-Address and subnetmask. To activate
the new settings, click rst on the button <Update IP settings> and then
on the button <System Restart>. After restart the gateway is congured
to the new IP address and subnetmask.
7. In order to access the ProtoCessor gateway, the IP address of your
laptop must be set to the same network as the ProtoCessor.

11
3.2.2 ModifyingtheBACnetNodeID
1. Enter the (new) IP address of the gateway in your internet browser and
conrm the entry with the Enter key. The FieldServer GUI will be started.
2. Select the menu point “Setup > File Transfer” in the “Navigation Tree”.
Then, click in the “Retrieve” section on the link “cong.csv” and save
the conguration le to the desired loaction on your laptop.
3. Open the conguration le “cong.csv” with a text editor, change in the
section “Server Side Nodes” of the window the Node ID to the appro-
priate value and save the conguration le.

12
4. Select the menu point “Setup > File Transfer” in the “Navigation Tree”.
Click in the “Update” section on the button <Browse...> and select the
conguration le you have modied. Then, click on the button <Submit>
in order to upload conguration le into the ProtoCessor.
As soon as the upload is nished a corresponding message appears
in the upper part of the window. Click on the button <System Restart>
to restart the system with the new settings. After restart the Node IDis
changed to the new value.

4.2 Conversiontablesgatewayvariables
The following tables show the ProtoCessor gateway varibales and their
BACnet/IP and LonWorks equivalents.
Note: the number at the end of the gateway variables (e.g. “_1”) indicate
the unit number (Modbus number) of the corresponding Nordmann AT4. If
there is only one Nordmann AT4 humidier, all variable names will end in
“_1”. If two units are networked together, the second unit’s variable names
will end in “_2”. For three networked units,… “_3” and so on.
