EU3000 main components:

  • User PC – computer(s) with INOVA TestControl user software
  • RTC – server with real time controller
  • I/O Base – peripheral unit (I/O module) sub-rack with transmission paths to both control computer levels
  • Synchroblock/CMUE – transmission paths’ central unit in separate rack module or integrated in the I/O Base
  • Power supply unit (PSU) – distributes power to the I/O Bases, computers and other devices in the system
  • Emergency stop safety circuits – integrated in the power supply unit or as a separate module

EU3000 System Flowchart

EU3000 System Functionality

The user PC and RTC feature highly reliable components to ensure a smooth and trouble-free run of the server-based application over a long time. The user PC is equipped with all standard peripherals for convenient use while the RTC server employs a high-speed Ethernet connection to the I/O cards mounted in the Inova sub-racks. In addition, the RTC server supports optional communication interfaces such as EtherCat, Flexray, CAN, RS-232, RS-485, Modbus RTU and Modbus TCP/IP, allowing glossy synergy with frequency converters, PLCs, distributed peripheries or other devices.

Voluminous data flow between the Inova I/O Base sub-racks and RTC computer peripheral units is controlled by a transmission system. These components are linked via the synchroblock or CMUE module into GBE channel frames without transmission speed losses. A much lower data volume is transmitted between the RTC computer and User PC through the 1 GB Ethernet interface.

The sampling of analog inputs and outputs is fully synchronous and independent of the number of I/O elements in the control system, allowing for a maximum actual input/output sampling rate of 50 kHz.

The whole system is powered from a common power supply unit. The mains appliances (computers and peripherals) and sub-rack electronic circuits are powered through the UPS backup power supply source. After a mains power supply failure the backup power source kicks in to ensure a safe shutdown of the entire system.

The emergency stop subsystem safely stops the system after the operator presses the e-stop button or a potentially dangerous situation is detected. The subsystem and its components are designed to meet the requirements of Performance Levels c to e (PLc to PLe). 

Basic Technical Parameters



Maximum number of sub-racks per subsystem


Maximum number of I/O units per sub-rack


Maximum number of subsystems in one system


Maximum control loops per system


Maximum I/O units per system


Distributed system – Master-slave up to 50 m


Analog input resolution

Small systems use a compact case containing a power supply, space for 8 periphery units and a simple emergency stop subsystem.

Operating and ambient conditions comply with CSN EN 60204-1, Section 4.4:

  • Electromagnetic compatibility (EMC) complies with Section 4.4.2
  • Relative humidity: max. 50% (at +28°C), 90% (at +20°C), in compliance with Section 4.4.4

Ambient temperature +10 °C to +28 °C, or 35 °C as an option.


Inova test rigs are delivered with the TestControl software suite, a proprietary graphical user interface with advanced features for a wide range of testing applications. TestControl communicates with the RTC server computer, which is directly connected to the I/O units, offering full control over connected hardware. In addition, TestControl can display and process data received from the RTC computer and provides the operator with a wide range of powerful features, such as the ability to create user-defined control loops, define loading sequences, data acquisition, online mathematical operations over measured signals (digital filtering, linearization etc.), data postprocessing, analysis and evaluation, managing calibrations etc.
