Network Integration
LonWorks.xif file
To facilitate the integration of a LonWorks unit within a network, it may be desirable to obtain an
External Interface File (XIF). Files of type .xif are used to convey the resources, specific objects
and data types which a LonWorks device possesses. The .xif file allows a network integrator to
simulate the presence of a networked humidifier even if it is not yet physically connected to the
network. In fact, if the integrator has the .xif files of all network devices, a complete system could
be simulated and configured off-line. Once the configuration is done, the integrator's software tool
can be connected to the actual system and the configuration information can be downloaded. If a
.xif file is required prior to installing a LonWorks-enabled humidifier, please contact the factory to
obtain it.
BACnet Pics and Bibs
The Protocol Implementation Conformance Statement or “PICS” describes the BACnet capabilities
of a particular BACnet implementation. It is a written document, created by the manufacturer of a
device, which identifies the particular options specified by BACnet that are implemented in the
device.
BACnet Interoperability Building Blocks (BIBBs) describe a list of services a BACnet device
provides. The main areas that the building blocks are concerned with include: data sharing,
trends, schedules, device and system management. BIBBs help specify the interoperability
capabilities of a BACnet device. Please contact the factory to obtain a PICS statement or BIBBs
profile.
NORTEC OnLine
Firewall Port 5222 must be open to TCP traffic in order for NORTEC OnLine to communicate
properly.
Variable Definition
In the variable name, “_ x ” denotes the humidifier number. If there is only one humidifier, all variable names will
end in “_1”. If two units are networked together, see Figure 4, the second unit’s variable names will end in “_2”.
For 3 networked units, “_3” and so on. If unsure of the unit number, each unit will have a label, in the electrical
compartment close to the terminal strip, indicating the device instance of each humidifier.
NORTEC Links 2 is capable of communicating a variety of variables for each unit that is connected
to it. For a variable listing and definition refer to Table 4. Network variable addresses for the
humidifiers may be seen in Table 5 to Table 12.
