Dual EtherCAT Data Buses for Maximum Data Integration 

OBSIDIAN data acquisition system is equipped with two fully independent EtherCAT bus systems that work in parallel.

The Primary Bus

When OBSIDIAN is switched to external master mode, the primary bus is used for perfectly timed and synchronized data acquisition. It connects to the PC running DewesoftX data acquisition software and streams any number of input and output channels at high speed to the PC's hard drive. 

The Secondary Bus

OBSIDIAN'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. Additional bus for redundant 3rd party data acquisition system in critical DAQ applications.

Excellent Connectivity With Standard Data Interfaces and Protocols

The acquired data is available to other data systems or controllers using standard data protocols:

  • EtherCAT: an industry standard for real-time control applications. OBSIDIAN uses two EtherCAT buses in parallel. When it is switched to external master mode, the primary EtherCAT bus is used for full-speed buffered data acquisition to a computer. In contrast, the secondary bus is mainly used to serve data in real-time to any 3rd party control system.

  • OPC UA: a leading standard for Industry 4.0 applications. The data can be served to SCADA, ERPs, MES systems as well as mobile clients in real-time.

  • CAN and XCP on Ethernet: with the XCP protocol you can provide the data to ECU calibration software such as ETAS INCA or Vector CANape in real-time with minimum latency.

Redundant Power Supply

IOLITE R8 and IOLITE R12 data acquisition systems are 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.

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 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.
