AcquiSuite Ally 12 & 48 User Guide (Rev D)

BACnet

Building Automation and Control Network (BACnet) protocol was developed under the auspices of the
American Society of Heating, Refrigerating and Air-Conditioning Engineers (ASHRAE) and is recognized as
an American National, European, and ISO global standard.
BACnet Device ID. All device IDs on a BACnet network must be unique. Refer to the section "Serial
Protocols" and refer to the Register List for additional information.
Serial
The AcquiSuite™ Ally Serial version supports writable max_master, MS/TP address,
max_info_frames properties in the device object for MS/TP networks. For best network
performance, the max_master should be set to the highest MS/TP MAC address on the network.
The MS/TP address (object 1069) must be unique on the MS/TP network. The max_info_frames
does not need to be changed in most installations.
Ethernet
Ethernet versions can register as Foreign Devices to a BBMD. BBMD stand for BACnet/IP Broadcast
Management Device. The BBMD IP address can be set from the Ally Configurataion Console, or
through character string object 2264. A value of 0.0.0.0 disables foreign device registration. This
process requires a processor soft reset.
BAC S
NET TRUCTURED
The AcquiSuite Ally meter supports the Structured View (SV) object container. If this option is supported
in the BACnet exploring tool, objects will be grouped logically into elements which can be named to reflect
electrical or physical locations, followed by system objects, as shown below for an AMC12 having elements
A-D.
Within each element, Structured View lists the BACnet objects by Object Type and then by numeric
number as shown below. In addition objects for elements are grouped in a "hotel room" scheme. That is
Element A (and system objects) have a range from 0-9999, Element B 10000-19999, Element 20000-
29999, to Element P on the AMC48 150000-15999. Some BACnet explorer tools have additional sorting
capabilities.
