Example 3
•
MAC=0, Max_Master=1
•
MAC=2, Max_Master=2
This is an incorrect configuration. The MAC=0 will never find MAC=2 because it will never poll for the master MAC
address=2.
Example 4
•
MAC=0. Max_Master=3
•
MAC=1, Max_Master=3
•
MAC=2, Max_Master=3
•
MAC=3, Max_Master=3
This is an efficient configuration as the units are numbered consecutively and the MAX_Master is set to the most
efficient value. As a general guideline, the most efficient setup for an MS/TP network is one in which the units are
consecutively numbered starting at MAC address 0 and having Max_Master=the maximum MAC address in the
system. If consecutive numbering is not possible, then the next most efficient setup is one in which all units have
Max_Master=the maximum MAC address in the system.
IP Port
For IP communication, a port number of
47808
(0xBAC0)
is used by default. Ensure that the BMS accesses the port
with which the humidifier communicates. Generally, in situations with multiple networks, different ports may be used
such as 47809 (0xBAC1) or 47810 (0xBAC2) to separate traffic.
Network Reset
Reset the humidifier via BACnet using the
Reinitialize Device
service. The Reinitialize Device service can be
accessed using the following password:
nep.
The Reinitialize Device service has two types of reset such as:
•
Warm Reset.
The Warm Reset changes the humidifier to its initial state.
•
Cold Reset.
The Cold Reset restarts the humidifier.
