Redundant EtherCAT Bus Systems

Each IOLITE data acquisition system is eqquiped with two fully independent EtherCAT bus systems that work in parallel. 

The Primary Bus

The primary bus is used for perfectly timed and synchronized data acquisition via Dewesoft X data acquisition software. The IOLITE connects via any EtherCAT RJ45 cable to the PC running Dewesoft X DAQ software and streams any number of input and output channels in high-speed tot he PC's the hard drive. 

The Secondary Bus

IOLITE's secondary EtherCAT bus can be used in two ways:

  1. Low latency front-end interface for any 3rd party EtherCAT compatible real-time controllers
  2. Redundant data acquisition system bus for critical DAQ applications

Perfect Signal Conditioning

IOLITE offers great signal conditioning. With its range of input and output slots, you can measure voltage, current, strain, stress, vibration, sound, temperature, digital, counters and so much more.

Proven high-quality data acquisition hardware combined with award-winning Dewesoft X data acquisition software performs data collection without losing even a single sample. It also provides great data visualization and processing capabilities.

Data can be stored in a time-series database, and served to SCADA systems using standard interfaces such as OPC UA or XCP to truly support Industry 4.0 applications.

Off-the-shelf Dewesoft X data acquisition software with a series of supported industry-standard interfaces makes IOLITE the perfect choice for even the most price-sensitive measurement and control tasks.

Data Acquisition and Control Combined

Until the IOLITE, the worlds of data acquisition and control were completely disconnected. Controller / PLC systems are dedicated to reacting to events as fast as possible, and recording data is a secondary concern. On the other hand, the data acquisition systems are made to acquire data as fast as possible, and doing real-time control is secondary or simply unavailable in many of them.

Very often test benches require both precise signal conditioning and processing, and real-time control. In the past, DAQ and PLCs were often connected by using analog connection - one cable for each signal.

This is where the IOLITE system shines with its dual independent EtherCAT buses. There is only one EtherCAT line between the PLC and DAQ. This greatly reduces cabling and eliminates redundant analog-to-digital conversion of the same signals. Finally, the different worlds of control and data acquisition are combined in one elegant system.

The Endless Possibilities

IOLITE - a perfect solution for your data acquisition and control applications. And this is just the start.

With its outputs, the IOLITE data acquisition and control system totally eliminates the need for the PLC hardware! Any PLC software can fully control the outputs of IOLITE.

Only your preferred EtherCAT based real-time controller software is needed, and the IOLITE system can drive the actuators.

There is no longer a need for two systems, one system can perform everything - Dewesoft IOLITE.

Input and Output Slots and Amplifiers

IOLITEs chassis can be configured with 12 IOLITE slots (IOLITEr) or 8 IOLITE slots (IOLITEs) each featuring high-quality input and output amplifiers. Currently, the following amplifiers are available:

  • 6xSTG: universal analog and strain gage amplifiers. Compatible with Dewesoft smart interface DSI adapters for expansion to Thermocouple, RTD, LVDT, current and IEPE measurements.
  • 8xTH: isolated thermocouple amplifier.
  • 8xRTD: isolated universal PTx temperature, resistance, and voltage.
  • 32xDI: 32 channel digital input.
  • 32xDO: 32 channel digital output with the watchdog functionality.

See the tech specs page for full technical specifications.

6xSTG - Universal Strain Gage Amplifier

Six-channel universal differential analog with 20 kS/sec per channel sampling rate. This module can acquire:

  • Analog voltage up to 50 V
  • Full, half and quarter bridge strain gage channels
  • Potentiometer
  • IEPE, Thermocouple, RTD, Current and LVDT channels (using DSI adapters)

It also features channel independent programmable power supply to power sensors.

8xTH - Universal Thermocouple Amplifier

Isolated thermocouple module can acquire data from any kind of thermocouple (K, J, T, R, S, N, E, C, U, B).

It offers software sensor break detection as well as using a hardware LED indicator.

8xRTD - Universal Resistance  Thermometer (PTx) Amplifier

8 isolated universal PTx temperature, resistance, and voltage input channels for PT-types

  • PT100,
  • PT200,
  • PT500,
  • PT1000,
  • PT2000

It offers software sensor break detection as well as using a hardware LED indicator.

32xDI - Digital Inputs

Digital input module with screw terminal and power supply is perfect for high channel count  data acquisition and control applications.

32xDO - Digital Outputs

Digital output module with screw terminal and power supply is great for control application with feedback monitoring. The module also includes watchdog function.

Redundant Power Supply

Every IOLITE data acquisition system is equipped with a redundant power supply completing the feature set for the ideal and reliable front-end system. 

If the primary power supply fails, the system will be powered by a secondary power supply without any interruption or system shutdown/restart.

Feedback Monitoring

What is really amazing is that IOLITE DAQ system gives the operator the capability to acquire and monitor the data in daily operation as well as while tuning the control systems.

Apart from monitoring the input channels on the data acquisition bus, the system can also monitor the outputs from the controller. Let's say we regulate the switch-off valve by monitoring the pressure. DEWESoft can show the pressure signal as well as digital output signal coming from the controller, all fully synchronized.

This allows the operator to prove that the control system is operating correctly every time.

IOLITEr - 19-inch Rack Cabinet Mount Chassis

Standard IOLITE aluminum chassis is compatible and can be mounted in any 19-inch rack cabinet. This is perfect for the test-bed installations.

The IOLITEr chassis height is 4U and can host up to 12 IOLITE I/O modules.


IOLITEs - Rugged Boxed Chassis

In addition to 19-inch rack cabinet compatible chassis, the IOLITE DAQ system is also available in standalone rugged aluminum chassis compatible with SIRIUS data acquisition instruments. 

The IOLITEs chassis provides 8 slots for IOLITE input and output slices to be installed.

Real-life Example - Durability Tests

Let’s look at a real-life example for IOLITE use.

Automotive durability test benches require hundreds of input channels for very precise data acquisition. They need to record force, torque, linear or angular motion, and more - and everything must be acquired with high precision and fast sample rates. 

Typically, the data acquisition devices are connected to PLCs which control the tests via analog outputs. So each analog output from signal conditioning is connected to inputs of PLC. Hundreds of signals … hundreds of cables … long set-up times and lots of work to connect everything.

But with IOLITE, only a single Ethernet digital interface is required to capture all of this data in real-time and then perform actions via IOLITE analog, digital or CAN outputs.

As a final touch, Dewesoft software monitors the performance of the controller, making sure that the controller and actuators are working flawlessly.

IOLITE is perfect for Industry 4.0 automation, automotive test benches, aerospace component testing, structural monitoring and alarming - just to name a few applications.

We are very happy that this dual bus technology is recognized and used already in the testing of the most advanced systems in the world, including testing a new engine for the most powerful European rocket ever built.
