1 Notes for the planning engineer
1.1 Overview
The @Link option allows the integration of Nordmann AT4 humidiers 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 specied secondary protocol.
The following protocol options are available and must be specied 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:

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 congurations 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 conguration. 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).

** Termination of the bus system: to ensure the correct function the bus system must be terminated on both ends. For that purpose a jumper must be set on
the connector “JP1-RS 485 Termination” on the control board of the rst and the last Nordmann AT4 unit in the bus system. On all intermediate Nordmann
AT4 units the corresponding jumper must be removed (see above diagram).

3 Conguration
3.1 ConguringtheNordmannAT4contolunit
The settings described below must be congured on each Nordmann AT4 unit (see Nordmann AT4
operating instructions regarding the operation of the control software):
1. Modbus settings
Select the Modbus menu, Path:
Mainmenu>User>Passwordentry:3562>Modbus>Networking
Set Modbus parameters as follows:
Modbus Adr.: desired Modbus address (range: 1...247)
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
Select the control settings menu, Path:
Mainmenu>User>Passwordentry:3562>Settings>Controls
Select the parameter “SignalSource” and set it to Modbus.

3.2 Gatewayconguration
The protocol conguration 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 SettingtheIPaddressandsubnetmask
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 modied
at any time via the integrated FieldServer GUI (Graphic User Interface) of
the ProtoCessor.
To congure 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 conrm 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 congured
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.
