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. Please refer to the wiring diagram section for a PICS statement.
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 Links2 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.
