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.

Network Reset
Reset the controller via BACnet using the

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 restarts the controller with actual configuration.
Cold Reset. The Cold Reset restarts the controller with
Factory configuration
.
Warning:
The Cold Reset erases the actual configuration when setting the MSTP address. Therefore, exercise
caution while performing a Cold Reset.
