BACnet MS/TP Simulator & Test Analyzer
BACnet MS/TP Simulator and Test Analyzer
A complete BACnet MS/TP master/slave stack and RS-485 test bench in one desktop app — built for engineers validating BACnet gateways, field controllers, and token-ring behavior on the bench or in the field.

Inside the app
Eight modules, one workflow
Everything runs on top of a single MS/TP stack on your chosen serial port, so a device you simulate in one tab is immediately visible to discovery, the test suite, and the activity chart in the others.
Dashboard
Connection status, live frame/error counters, and recent bus activity at a glance.
Connection
Port, baud rate, data bits, parity, stop bits, MAC address, and Master/Slave mode.
Devices
Quick-template or custom simulated devices, object monitor, and COV subscriptions.
Activity
A live TX/RX/total line chart of frame traffic on the bus over time.
Test Suite
Pick a Device Under Test, choose categories, and run the automated test catalog.
Logs
Separate Frame Logs and Application Logs, filterable and exportable to CSV/text.
Settings
Export preferences and general application configuration.

A closer look
Built for the parts of MS/TP that are actually hard to test
Stop waiting for a real field device to test against
- Quick templates build a full 7-object device — AI, AO, AV, BI, BO, BV, MSV — in one click
- Custom devices let you set device name, device ID, MAC and value mode
- Each object runs an independent value mode: Fixed or Random
- Live object monitor and a COV subscription table with lifetime and notify counts
- Import or export a device list instead of rebuilding it by hand
Validate the whole MS/TP path, not just one read
- Pick a Device Under Test — simulated or a real slave/master on the bus
- Run the full catalog or just the categories you need: Discovery, Token Passing, Read, Write, COV, Error Handling
- Every step logs total requests, successes, failures, timeouts, and average response time
- Falls back to sequential writes automatically if WritePropertyMultiple isn’t supported
- Exports a full pass/fail PDF report for commissioning sign-off
See the token ring and the traffic, not just the outcome
- A live TX/RX/total line chart tracks frame counts on the bus in real time
- Separate Frame Logs and Application Logs tables, each filterable
- Frame stats cover sent, received, CRC errors, malformed frames, and token passes
- Export activity and logs to CSV or plain text for later review
- Inject malformed MS/TP octets to confirm the stack stays healthy under bad input
Everything you need to validate a
BACnet MS/TP network
Each module covers a distinct part of MS/TP commissioning — from RS-485 link setup to standards-accurate token timing.
