MPM BACnet Integration

[#1]

Issue

How can objects of a SmartStruxure™ Lite network be made available as BACnet points to third party BACnet building management system (BMS)?

Product Line

EcoStruxure Building Operation

Environment

SmartStruxure Lite

BACnet

Cause

The BACnet protocol is always active, as long as the network cable is connected. However, two different BACnet options can be selected: IP or Ethernet. The default option is Ethernet and this will need to be changed if BACnet over IP is required.

Resolution

The BACnet protocol is always active, as long as the network cable is connected. However, two different BACnet options can be selected: IP or Ethernet. The default option is Ethernet.

1. To verify or to change which BACnet protocol is currently in use, select the SmartStruxure Lite Manager that you want to configure from the left-side Network panel.
2. Then choose the BACnet configuration list item.

3. Define the Network Number (if the protocol selected is BACnet IP).

   Note:

   The Network number must be defined only on the monitor Manager. It shall be different then the Parent Network where the monitor is connected.

   A BACnet Device is uniquely located by a network number and a MAC address. Creating two or more B/IP networks, each with a unique network number, can be useful for limiting the propagation of local broadcast messages and for providing security by confining traffic to a particular geographic or logical area.

4. Select the desired protocol type from the drop-down list between BACnet IP and BACnet Ethernet.

5. Then choose an optional port number (if the protocol selected is BACnet IP). Default is 47808.

6. Select the BACnet Priority of the BACnet write action of the SmartStruxure™ Lite's network monitor. Default is 10.

   Note:

   SmartStruxure™ Lite does not support BACnet Write Priority, per se. However, in Firmware version 2.4.x and newer, it is possible to assign the write priority for all SmartStruxure™ Lite BACnet points. Default value is 10, except if you upgrade a Manager using a version 2.3.x or older, BACnet priority will be 8, but can be changed.

7. Click the Save button to apply the configuration changes.

8. Click hit the Save All button to make the modifications permanent and reboot the Manager for the new options to enter into effect.

9. Change the BACnet instance number of the Manager if required.

IMPORTANT

Each Manager must have a unique BACnet device instance number. A Manager device instance number can be changed by selecting the top-left icon inside the left-side Network panel.
