4.10.3.6.16. Password conguration

These variables allow you to lock or unlock access to the programming menu, and also allow

you to change the password code. The password code may only be changed through this com-

mand.

The unit does not need you to enter the old password in order for it to record the new one; it

records the new one directly without any verication.

4�10�4� BACnet PROTOCOL

BACnet is a communications protocol for Building Automation and Control NETworks. This

protocol replaces the proprietary communications of each device, making it a set of common

communication rules that enables the complete integration of the building automation and

control devices of different manufacturers.

The unit features BACNet MS/TP communications, following the specifications of ANSI/

ASHRAE 135 (ISO 16484-5).

Using a RS485 connection, the unit can connect to a BACnet and include all of the objects and

services dened in the attached PICS map (Protocol Implementation Conformance Statement).

( “4.10.5. PICS MAP”)

The default speed is 9600 bps and the MAC is 2 (node number), and can be changed on the

conguration screen or by entering the BaudRate and MAC_Address variables. The identier

(Device_ID) can be changed on the conguration screen using the writing property over the

variable or through the Device_ID variable.

Another option is to overwrite the Object_Name in the Device object:

a) #Baud x – where x can be: 9600, 19200

b) #MAC x – where x can be: 0 ... 255

c) #ID x – where x can be: 0 ... 999999

For further information on the protocol: www.bacnet.org.
