(3) GATEWAY CONFIGURATION
(1) Protocol configuration is made at the factory, prior to final testing. Baud rates are
also adjusted to the following values:
Table 2. Baud Rates
Protocol Default Baud Rates
BACnet MS/TP 38.4 kbps
BACnet / IP 10BaseT
Johnson N2 9.6 kbps
(2) For BACnet/IP, BACnet/MSTP and Johnson N2 applications, it is necessary to
establish the modules network address parameters in order access it. Address
assignments can be configured at the factory or Nortec can provide instructions to
modify the address settings in the field.
(4) NETWORK INTEGRATION
(A) LONWORKS.XIF FILE
(1) 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.
(B) BACNET PICS AND BIBS
(1) 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.
(2) 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.
