Easy channel count expansion
Increasing your channel count is straightforward with the EtherCAT® expansion feature. By simply connecting additional data acquisition systems like KRYPTON®, IOLITE®, or another OBSIDIAN®, you can easily increase your system’s capabilities. The beauty of this setup lies in its simplicity and efficiency: systems can be extended using a daisy chain topology, meaning you only need a single cable to connect each device*. This one cable handles everything – power, synchronization, and data transfer between devices.
This design simplifies scaling up your data acquisition setup and minimizes the clutter and complexity of managing multiple connections. Whether you’re looking to add more channels for comprehensive data collection or need to adapt to growing project demands, this streamlined approach makes expanding your system fast and easy.
* Expanding OBSIDIAN with IOLITE or another OBSIDIAN requires a power supply via a 2-pin power connector.
Excellent connectivity with standard data interfaces and protocols
The data collected by OBSIDIAN® systems is easily accessible to other devices such as third-party devices, controllers, test benches, and SCADA systems. Standard data protocols ensure easy integration with other systems:
-
EtherCAT®: Recognized as an industry standard for real-time control applications, OBSIDIAN can operate dual EtherCAT buses simultaneously. In external master mode, the primary EtherCAT bus facilitates high-speed, buffered data acquisition directly to a computer. Meanwhile, the secondary bus primarily offers real-time data to any third-party control system, ensuring timely and efficient data transfer.
-
OPC UA: A cornerstone for Industry 4.0 applications, OPC UA allows OBSIDIAN to provide data in real-time to SCADA systems, ERPs, MES, and even mobile clients, enabling seamless integration across a broad range of industrial applications.
-
CAN and XCP on Ethernet: Through the XCP protocol, OBSIDIAN can deliver data in real-time to ECU calibration software, such as ETAS INCA or Vector CANape, with minimal latency. This ensures that data is quickly and efficiently processed, ideal for tasks requiring precision and speed.
Dual EtherCAT®data bus
The OBSIDIAN® devices feature two completely independent EtherCAT® bus systems operating in parallel.
CAN and CAN-FD data logging
OBSIDIAN® devices have the capability to log and decode CAN and CAN FD streams through the following connections:
-
Integrated CAN bus ports:
-
The back panel of OBSIDIAN systems includes two integrated CAN bus ports.
-
These ports support standard CAN 2.0b data but are not compatible with higher-speed CAN FD buses.
-
-
IOLITEir 4xCAN-FD expansion card:
-
This card can be inserted into any available card slot.
-
It supports data rates up to 5 Mbit/s with a single bus or up to 2 Mbit/s when all four bus channels are used simultaneously.
-
All four channels are backward compatible with CAN 2.0.
-
Additionally, OBSIDIAN® supports OBDII and XCP/CCP protocols when configured to run as a standard data acquisition system connected to DewesoftX software.
When OBSIDIAN® operates in stand-alone data logger mode, the embedded DewesoftRT software allows logging raw CAN data streams and decoding up to 100 CAN bus channels (including SAE J1939) in real-time. The decoded channels can be used in trigger conditions. All raw CAN bus data can also be decoded offline using DewesoftX software.
Integrated GNSS positioning
The OBSIDIAN® R8w systems come equipped with an embedded GNSS sensor designed for precise location tracking. This 10 Hz GNSS sensor is compatible with multiple satellite constellations, including BeiDou, Galileo, GLONASS, and GPS/QZSS, ensuring accurate positioning within 2.5 meters and velocity accuracy up to 0.05 meters per second.
With this integrated GNSS sensor, you can effortlessly monitor and record various parameters such as:
-
Longitude
-
Latitude
-
Altitude
-
Velocity
-
Number of satellites
Please note, that the current version of embedded GNSS does not yet support RTK (Real-Time Kinematics) correction, but this advanced feature is expected to be available soon.
All OBSIDIAN devices also support the connection of external GNSS sensors via the USB-C connector. Any of our USB-type GNSS receivers can be used.
Merging data acquisition and real-time control
Historically, data acquisition and real-time control existed in different worlds, and there was no overlap. Controllers, including PLC systems, prioritized rapid response to events, and data recording was a secondary function. At the same time, data acquisition systems focused on recording speed, neglecting real-time control completely.
However, many applications require both functionalities. For example, test benches require precise signal conditioning and signal processing, along with real-time control. Integrating DAQ instruments and PLCs required redundant cabling, each dedicated to a specific signal.
The introduction of the Dewesoft EtherCat-based systems like OBSIDIAN,IOLITE, andSIRIUS RTchanged the landscape by offering dual independent EtherCAT data buses. With this innovation, one bus could be used for high-speed, buffered data acquisition and the bus could send low-latency data to third-party controllers.
With today’s Dewesoft instruments, only one data bus is needed between the PLC and the DAQ, drastically reducing cable complexity. This not only simplifies installation but also avoids unnecessary analog-to-digital hardware on the controller side. Dewesoft systems elegantly merge control and data acquisition, solving the integration of DAQ and real-time control once and for all.
This feature is available to any third-party controller software with EtherCAT master enabled. Dewesoft systems can easily command and control actuators, for example.
The days of requiring two independent systems are gone – Dewesoft does it all.
