DewesoftRT: embedded data acquisition software
OBSIDIAN® systems now utilize the new DewesoftRT embedded data acquisition software. This is a versatile, cross-platform software designed to operate on the OBSIDIAN’s Linux system, powered by an integrated ARM processor. “RT” stands for real-time and is designed from the ground up to work in real-time scenarios.
DewesoftRT features a streamlined core, including components for data acquisition, channel configuration, data storage, and support for standard interfaces like OPC-UA, XCP, CAN, USB, Ethernet, and EtherCAT. It’s flexibility and modular design make it easy to customize and adapt quickly for specific applications or tasks.
Future iterations of DewesoftRT software will also add openDAQ™ support and include math capabilities, such as online calculations, simple math formulas, statistics, fatigue analysis, and more.
The software excels in fast data transfer and real-time operations, such as control mechanisms or watchdog functionalities. Over time, DewesoftRT’s capabilities will evolve based on user and application requirements. If you have a specific application in mind, we encourage you to get in touch with us.
Stand-alone data logger mode
When set up for stand-alone operation in data logger mode, OBSIDIAN® devices offer versatile data storage directly on the device through several options:
- 4 GB of built-in SSD storage for quick and efficient data saving.
- An SD card slot that supports adding extra storage up to 1 TB, providing ample space for extensive data collection.
- A USB Type-C port that facilitates the connection of external hard drives, further expanding storage capabilities.
OBSIDIAN® data loggers are capable of handling a wide range of input channels at maximum sampling rates, making them ideal for various data recording tasks.
Additionally, the DewesoftRT data logger software comes with multiple standard features for data storage, including:
- Trigger-based saving, which allows data to be stored automatically when specific conditions are met. Triggered storing can work on any input channel including CAN bus channel.
- The option to save data in either a single file or multiple files.
Anyone can review and analyze stored data files using the included DewesoftX software, which is an award-winning tool for data acquisition and signal processing.
High-end signal conditioning
OBSIDIAN® devices offer exceptional signal conditioning capabilities, accommodating a wide variety of input and output modules. These modules are capable of measuring a diverse range of signals including:
- Voltage and high voltage
- Current
- Resistance
- Strain, stress, and force.
- Sound and vibration (IEPE and charge)
- Temperature (thermocouples and RTDs)
- Digital counters
- And others
Multi-channel amplifier cards offer data in 24-bit resolution, alias-free with high dynamic and low SNR. Sampling rates are software selectable per each input channel and offer acquisition speeds up to 20 kS/s.
The combination of Dewesoft’s high-quality data acquisition hardware and software ensures that data collection is seamless and precise, without missing a single sample. Robust data visualization and signal processing features are available through the included DewesoftX software.
