330-668-1444WinDaq™ Direct Automated Test Sequencer
bridging the gap between simple data logging and complex programmatic test systems.
- Zero-Install Execution: The entire logic engine runs locally in your web browser. No plugins, no software to download, and no cloud processing required.
- No-Code Visual Builder: Construct complex automated tests using a simple, web-based flowchart editor. Define your states, conditions, and actions without writing a single line of code.
- Advanced Math Triggers: Trigger actions based on live signal analysis. Note: Time resolution for trigger testing is roughly 50Hz
- Intelligent Data Logging: Save hard drive space and analysis time. Command the sequencer to automatically pause and resume CSV data recording only when specific physical events occur.
- Digital I/O Automation: Automatically drive individual digital output pins (D0-D6) High or Low to control external relays, alarms, or shutoff valves based on live sensor data.
- JSON Sequence Portability: Export your entire test flow as a lightweight JSON file. Share test profiles with colleagues or load them instantly to replicate exact testing parameters across different workstations.
- State Machine Architecture: Build robust multi-step tests using sequential logic and delay timers (e.g., Wait for threshold -> Start Log -> Wait 5 mins -> Stop Log -> Reset).

Introducing the WinDaq™ Direct Sequencer
The WinDaq™ Direct Test Sequencer bridges the gap between simple data logging and complex programmatic test systems. Built natively into the WinDaq Direct web portal, this advanced Rule Engine and Finite State Machine (FSM) gives your DATAQ hardware the brains of an automated controller—directly from your web browser.
In the past, running conditional tests required manually staring at a scrolling waveform or writing complex scripts in languages like Python or LabVIEW. With the WinDaq Direct Sequencer, engineers and technicians can easily automate mechanical, environmental, and life-cycle tests using a visual logic builder.
Because the engine processes mathematical conditions on the live data stream before it even hits your hard drive, it can react to anomalies, cycle external hardware via Digital I/O, and intelligently gate data logging. Whether you are running a 48-hour thermal soak or capturing intermittent electrical faults, the Sequencer acts as a tireless digital lab assistant, ensuring you capture exactly the data you need, precisely when you need it.
Sample Applications
1. Thermal Soak & Environmental Chamber Testing
The Problem: An engineer needs to log data only when a motor reaches its operating temperature, record for a 30-minute soak period, and safely shut down the test.
The Sequence:
Step 1: Wait until CH1 (Thermocouple) > 85.0°C.
Step 2: Action: Resume Data Logging. Action: Delay Timer (1800 seconds).
Step 3: Action: Set DIO Bit 0 (Cooling Fan Relay) to High. Action: Pause Data Logging. End Test.
2. Power Quality Monitoring
The Problem: Monitoring a power line to ensure the RMS voltage stays within safe operating limits, triggering an alarm if it drops.
The Sequence:
Step 1: Monitor the AC signal using math: RMS(CH1) < 110.0.
Step 2: Action: Set DIO Bit 2 (Audible Alarm) to High. Action: Resume Data Logging. Action: Delay Timer (10 seconds).
Step 3: Action: Set DIO Bit 2 to Low. Action: Jump back to Step 1.
