BACnet Integration & Multi-Protocol BAS Work

BACnet/IP network design

Subnet planning, BBMD (BACnet Broadcast Management Device) configuration for routed networks, foreign device registration where needed, and Device Instance ID schemes that scale across buildings.

BACnet MS/TP trunk design

RS-485 trunk segmentation, MAC addressing, baud-rate decisions, biasing and termination, and tools-based troubleshooting when a trunk goes flaky.

Device discovery and object mapping

Whois/Iam discovery, manual device addressing where required, object property reads, and clean exposure of controlled equipment as BACnet objects to the supervisor.

Gateway integration for non-BACnet equipment

Modbus RTU/TCP-to-BACnet gateways for chillers, VFDs, meters, and generators. LON-to-BACnet for legacy installations. Custom point mapping and scaling documented per device.

BACnet/SC migration planning

BACnet/SC (Secure Connect) is the modern, TLS-secured transport. We plan and pilot BACnet/SC deployments where customer security requirements demand it.

Documentation that doesn't lie

Device Instance ID list, object naming conventions, MS/TP MAC map, network topology, and a maintained as-built BACnet point list per building.

Network audit and protocol plan

Walk the building, identify every device that does or should speak BACnet, document existing addressing chaos, and produce a target network design.

Addressing scheme and Device Instance IDs

Design a Device Instance ID scheme that's unique across the building and predictable to read. Plan MS/TP MAC addresses by trunk. Document everything before configuration begins.

Discovery and integration

Bring devices online segment by segment, validate discovery, verify every object reads true value, and bind the supervisor (Niagara or otherwise) to the discovered points.

Gateway work and exception handling

For non-BACnet equipment, set up gateways with point-by-point Modbus or LON-to-BACnet maps. Validate values against the equipment's native interface before going live.

Documentation and turnover

Deliver a complete BACnet network diagram, object list, gateway configuration backups, and a written operations playbook for the network.

Building with controls from Trane, Carrier, Daikin, and JCI — each with its own proprietary or partial BACnet implementation. We discover what we can, gateway what we have to, and present a single normalized BACnet network to the supervisor.

Chillers and pumps reporting Modbus only. We install Modbus-to-BACnet gateways, map every status, alarm, and setpoint to clean BACnet objects, and expose runtime data to the BAS for trending and optimization.

Generators and automatic transfer switches reporting via Modbus or proprietary protocols. We gateway them onto BACnet so emergency power status appears on the BAS alongside HVAC.

Electrical, water, gas, and BTU meters speaking Modbus RTU on RS-485 trunks. We translate to BACnet, expose cumulative and demand values, and feed energy dashboards.
