One tool for mixed buildings · Windows 10/11
One tool for every device in the building
The AHU speaks BACnet. The energy meters and drives speak Modbus. Stop carrying two tools. BACManager discovers, browses and writes BACnet/IP, MS/TP and Modbus RTU/TCP devices — property browser, schedule & calendar editor, EDE export, COV — all from one native Windows window. No BMS, no engineering workstation, no per-point licensing.

// one tool, every device
BACnet and Modbus, one app
Real buildings are mixed. The AHU talks BACnet; the energy meters and drives talk Modbus. BACManager speaks both.
Real buildings are mixed. The air handlers and controllers talk BACnet; the energy meters, VFDs and solar inverters talk Modbus. Every other tool forces you to pick a side — a BACnet explorer that ignores your meters, or a Modbus poller that can't see your controllers. BACManager does both natively: discover and browse BACnet/IP and MS/TP devices, and poll Modbus RTU or TCP devices on the same site, each on its own port, side by side. Walk into a plant room, plug in, and read everything with one window open.

Tools neededJust one
Need advanced Modbus features — dashboards, alarms, historian, scripting? Our dedicated Modbus tool ModbusManager goes deeper. BACManager covers the everyday Modbus reads you hit during BACnet commissioning.
// what it does
Everything for on-site commissioning
One native Windows tool for discovering, inspecting and configuring the BACnet and Modbus devices on a site.
🔍
Device discovery
Broadcast or directed whoIs across BACnet/IP and MS/TP. Find every device, its ID, name and address — including devices behind routers via BBMD foreign-device registration. Scanner guide →
📁
Property browser
Browse the full object list of any device. Read and write any property, see the raw decoded values, and inspect priority arrays — not just present-value.
📅
Schedule & calendar editor
Read and write weekly Schedule objects and Calendar objects directly — an editable grid for daily times and values, exception schedules and calendar dates.
📤
EDE & CSV export
Export a device object list as BACnet EDE 2.3 — importable by other BACnet tools and BMS engineering software — or as plain CSV for documentation.
⚡
COV subscriptions
Subscribe to Change-of-Value notifications and watch values update live, without polling — exactly as a real BMS would receive them.
🔢
BACnet and Modbus
BACnet/IP, MS/TP over RS-485, and Modbus RTU/TCP — all in one app. Commission the BACnet controllers and read the Modbus energy meters on the same site without switching tools.
🔌
BACnet ↔ Modbus gateway
Bridge either direction from one PC — expose Modbus meters as a BACnet device for a BMS, or a BACnet device as a Modbus map for a PLC. Publishes to MQTT and Home Assistant too. Priority-aware writes, runs unattended in the background. Gateway guide →
// RS-485 field devices
Real MS/TP, not just IP
Most BACnet tools only speak BACnet/IP. The field devices — VAV boxes, room controllers, thermostats — are often MS/TP only.
BACManager includes a full MS/TP master-node implementation over RS-485: it joins the token ring, answers Poll-For-Master, and reads and writes confirmed requests just like a native device. Point a USB-RS485 adapter at an MS/TP segment, pick the baud rate and MAC, and the same property browser, schedule editor and EDE export work exactly as they do over IP. And because Modbus RTU and BACnet MS/TP each run on their own COM port, you can even run alongside a Modbus session on a second adapter.
MS/TP connection fields — serial port, baud rate, MAC address
// schedule + calendar
Read and write schedules
View and edit BACnet Schedule and Calendar objects directly on the device — no engineering tool required.
Open a Schedule object and BACManager shows an editable weekly grid: time and value pairs for each day, the schedule default, what it writes to, and its exception schedules. Calendar objects show their date entries — specific dates, ranges and recurring weekdays — all editable and writable back to the device. The schedule and calendar codec has been validated byte-for-byte against independent reference BACnet stacks, so what you write is exactly what the standard specifies.
The things a careful buyer asks before paying for a commissioning tool.
Aren’t there free BACnet tools already?
Yes — and they are good at BACnet. But they are BACnet-only. The moment your site also has Modbus energy meters, VFDs or inverters — which most buildings do — a BACnet-only tool leaves you switching to a second app. BACManager is the one tool that reads both, so you are not paying for BACnet you can get free; you are paying to stop carrying two tools.
Is the BACnet side a real implementation?
Yes. Full device discovery (whoIs, including devices behind routers via BBMD/FDR), complete object-list browsing, read and write of any property, COV subscriptions, and a Schedule & Calendar editor. The schedule and calendar codec is validated byte-for-byte against independent reference BACnet stacks.
Does it do MS/TP, or just BACnet/IP?
Full MS/TP master-node support over RS-485, alongside BACnet/IP. Point a USB-RS485 adapter at an MS/TP segment, pick the baud rate and MAC, and the same browser, schedule editor and EDE export work exactly as they do over IP. The field devices that are MS/TP-only — VAV boxes, room controllers — are reachable too.
How deep is the Modbus support?
Modbus RTU and TCP polling — the everyday reads you hit during commissioning: registers, coils, common data types and scaling. If you need heavy Modbus work — dashboards, alarms, historian, scripting — our dedicated tool ModbusManager goes further. BACManager covers the Modbus you meet while commissioning BACnet.
One-time price, or subscription?
One-time. $149 buys the tool with 12 months of free updates. No subscription, no per-point fees, no cloud dependency — it runs entirely on your Windows machine.
