Sharing devices associated with an A7810, A8810, A8812 to a BACnet/IP network

This article may be helpful for the following reasons:

• Wanting to share devices and datapoints on the Device List of the EMH via BACnet/IP
• Requesting information in advance so that the EMH is programmed to work with the on site BACnet network
• Having difficulty seeing/detecting the instance ID#s and subsequent objects from the EMH

What items do I need to know from the person managing the BACnet network to program into the EMH to have its devices appear on the BACnet network?

• BACnet UDP Port: (default: 47808)
• Virtual Network Number: (1-65534)
• BBMD mode: [Three options below]
  • Disable all bbmd features
  • Allow incoming FDR
  • Full BBMD
    • If full BBMD, a list of IP addresses can be entered by IP : PORT
      example: 192.168.1.1:47808, 192.168.2.1:47808
• BACnet base object ID: (1-4194302)
  [The EMH will share the meter data on band of ID numbers starting from the base object ID# through base+255]
• BACnet base object name: (ex. ELEC_RM_NORTH , ROOM105)

If a Leviton technician is providing the programming services to the EMH to share the datapoints to your on site BACnet system, please provide the information above for each EMH on site when coordinating with them.

Where should I go to program the EMH to begin sharing devices and datapoints on the BACnet network?

1. BACnet > Gateway
   1. Meters shared via BACnet is set to All
   2. All items below are showing green check mark status
   3. Check BACnet base ID# setting on that page, and note this number (this is the base object instance number)
2. BACnet > Setup
   1. Confirm BACnet port matches that of the other devices
   2. Adjust virtual network number if needed
   3. Set BBMD mode and distribution accordingly; typically needed when IP of EMH is not on the same subnet as the BACnet system
3. BACnet > Discover
   • Scan Device ID# between the base object instance number and the base+250 . Devices on the Devices > Device List should appear on the screen, indicating what BACnet instance numbers they are located on.
     • On any of those line items, click the "objects" link for object datapoint listing with the associated analog input #’s. These can be listed as a BACnet EPICS template if desired by clicking the appropriate button.

Note: As object numbers and datapoint lists are generated as the EMH is programmed, it is often not possible to have a finalized objects listing prior to completion of the on site setup.

Example:

BACnet configuration where base object ID# located under BACnet > Gateway (246000)

BACnet object ID#s of each device from the device list. Click into the BACnet Objects link of the device in question to view the datapoint listing & EPICS

Example EPICS statement showing the points list for BACnet object #246005

Example EPICS statements are provided below. These are examples based on the EMH being configured using the typical datapoint mappings our Leviton Techs will use to read the devices. As customization is possible and when meeting certain customer requirements, the list of available datapoints may change.

Series 7000/7100 PICS datapoint listing. The number of device object ID#s per meter The 71D03 for example, is one device instance so it will have a BACnet object number assigned to it. The 71D48 would have 16.
Series 7200/7300 PICS datapoint listing. This meter will have all 24 virtual metering elements available under one device object ID#.
