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.
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.
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.
One native Windows tool for discovering, inspecting and configuring the BACnet and Modbus devices on a site.
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.
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.
Read and write weekly Schedule objects and Calendar objects directly — an editable grid for daily times and values, exception schedules and calendar dates.
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.
Subscribe to Change-of-Value notifications and watch values update live, without polling — exactly as a real BMS would receive them.
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.
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.
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.
Most engineers carry a BACnet explorer and a Modbus tool. On a mixed site that means two apps, two windows, two workflows. BACManager is one.

The things a careful buyer asks before paying for a commissioning tool.
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.
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.
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.
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. $149 buys the tool with free updates within the major version. No subscription, no per-point fees, no cloud dependency — it runs entirely on your Windows machine.
