Annex A - BACnet and Modbus Objects
The E Point Network can be factory configured with optional
3
communication types: BACnet or Modbus. Each of these communication
protocols has its own specific objects.
Honeywell recommends that appropriate measures be taken to ensure
security since BACnet and Modbus are not inherently secure. The installer
takes all responsibility for protecting the controller from malicious network
traffic.

BACnet Configuration

The E3Point is an MSTP Master Device and supports Dynamic Device
Binding (WHOIS/IAM), which is part of BACnet protocols DM-DDB-B
and DM-DOB-B (see the
Statement

BACnet Objects Descriptions

Each measurement type has Analog Input (AI), Analog Value (AV), Binary
Output (BO) and Binary Value (BV) objects. The table below defines each
object and lists the default setting:
