IOLITE R8/R12 
ETHERCAT Data Acquisition and Real-Time Control System

Merging Data Acquisition and Real-Time Control

Until the IOLITE system, the worlds of data acquisition and control were completely disconnected. Controller and 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 an analog connection - one cable for each signal.

This is where the IOLITE system shines with the dual independent EtherCAT buses. Only one EtherCAT line is required between the PLC and DAQ. This greatly reduces cabling and eliminates redundant analog-to-digital conversion of the same signals. The 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 an IOLITE DAQ system.

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 independent systems. One system can perform everything - Dewesoft IOLITE.

High-Channel-Count Applications

IOLITE data acquisition and control systems offer perfect and cost-efficient installation for high-channel-count applications. Systems can be daisy-chained together and can reach hundreds or even thousands of I/O channels. The channel count is only limited by the bandwidth limit. 

With Dewesoft NET configuration, systems can even be dislocated and distributed into several locations and act as one DAQ system controlled from the central control room.

With 19'' cabinet compatibility, IOLITE R12 systems can easily be installed in your existing cabinet infrastructure. 

Feedback Monitoring

What is really amazing is that the 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 easily 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.
