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, and SIRIUS RT changed 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.
