Introduction
The SKH High Pressure Atomiser Humidifier BACnet
®
Communication Module User Guide provides information about
using the humidifier with BACnet communications feature. The BACnet communication protocol for building automation
and control networks enables communication between client devices within a network. The humidifier provides a BACnet
network interface between BACnet client devices and Neptronic Humidifier series devices. It uses the BACnet Master
Slave/Token Passing (MS/TP) protocol at the BACnet MAC layer.
Pre-requisites
The BACnet communication user guide assumes that you are familiar with the concepts of BACnet and its terminology.
Advantages of BACnet
BACnet enabled humidifiers have the following advantages:
•
Quick Message Transmission.
The humidifier uses a synchronous implementation for BACnet messages making
it quick and efficient. Each BACnet confirmed service request is answered as quickly as possible without using
the
Reply Postponed
frame. The MS/TP implementation is performed within
Tusage_delay
of 15 minutes to
ensure a
Tusage_timeout
value within 20 minutes.
•
MS/TP Support.
The humidifier supports a Full Master Node state machine for MS/TP. Max_Master and the
instances are configured to the device object through
BACnet WriteProperty
service. The MAC address is set
via the DIP switches. Programming mode determines the MS/TP baud rate setting of 9600, 19200, 38400, and
76800. In the configuration mode, the device is configured through the device’s keypad. For more information
about the WriteProperty, refer to
Table 3 - Object Types Supported
•
BIBB Support
. The humidifier functions the same way as the B-ASC type profile server and supports the specific
BIBB as per their relevant definitions.

Object Support
. The humidifier supports a fixed list of BACnet visible values, which appear as Present_Values
of various BACnet standard object types in addition to a device object. For more information, refer to
•
Alarms
. The humidifier supports indication of various alarm conditions through value changes in properties of
several objects. However, it does not generate BACnet event notifications.
