ETAS ES600.2 PLC Module

The ETAS ES600.2 is a programmable logic controller (PLC) module designed for rapid control prototyping and hardware-in-the-loop (HIL) simulation in automotive and industrial environments. Part of the ETAS ES600 series, this module provides real-time data acquisition, signal generation, and communication with engine control units (ECUs). It is commonly used in development labs for validating control algorithms before production.

Technical Specifications

The ES600.2 features a high-performance 16-bit microcontroller (Infineon C166 family) running at 40 MHz. Memory: 1 MB RAM, 2 MB flash. Analog inputs: 8 channels, 12-bit resolution, ±10V or 0-5V range, sample rate up to 100 kHz total. Analog outputs: 4 channels, 12-bit, ±10V, update rate 50 kHz. Digital I/O: 16 channels, 5V/24V compatible (programmable direction). Timing I/O: 2 incremental encoder inputs, 4 PWM outputs, 2 frequency measurement channels. Communication: 2 CAN interfaces (ISO 11898), 1 LIN, 1 RS232, and 1 Ethernet (10/100). The module is powered by 24V DC (8-36V range) and consumes 250 mA typical. It is housed in a compact metal enclosure (200 mm x 130 mm x 45 mm) with D-sub connectors. Operating temperature -20°C to +70°C. Protection IP20.

Key Features

• 8 analog inputs, 4 analog outputs, 16 digital I/O

• Dual CAN, LIN, and Ethernet interfaces

• Real-time simulation and data logging

• Programmable via MATLAB/Simulink (ETAS ASCET or RTA-OS)

• Supports XCP calibration protocol

• Robust for automotive and industrial environments

• High-speed signal capture and generation

Programming and Software

The ES600.2 is programmed using ETAS ASCET or directly from Simulink using the ETAS RTA-Target Link. It runs an OSEK-compliant real-time operating system. Users can create control models, compile them to C code, and download to the module via Ethernet or CAN. The module supports online parameter tuning and signal measurement via XCP on CAN or Ethernet. For HIL testing, the ES600.2 can be integrated with ETAS LabCar or INCA systems.

Applications

Typical applications include engine control prototyping, battery management system development, chassis control HIL simulation, and industrial drive validation. Its compact size and ruggedness allow it to be used in vehicle or test bench environments. The module can simulate sensors (e.g., throttle position, temperature) and read actuator responses.

I/O Configuration

Analog inputs are configurable via software as voltage or current (with external shunt). Each input has a 15V overvoltage protection. The analog outputs can sink/source up to 10 mA. Digital I/O levels are selectable (5V TTL or 24V) by external pull-ups. The encoder inputs support incremental encoders up to 1 MHz. PWM outputs have programmable frequency (1 Hz to 100 kHz) and duty cycle.

Communication and Networking

The two CAN interfaces support CAN 2.0A/B, baud rates up to 1 Mbit/s. The LIN interface is master-capable. The Ethernet port supports TCP/IP, UDP, and XCP on Ethernet. The module can act as a gateway between CAN and Ethernet.

Power and Environmental

The wide input voltage (8-36V DC) allows operation from 12V or 24V vehicle batteries. Reverse polarity and overvoltage protection are built-in. The housing is designed for shock and vibration (ISO 16750-3). It is not waterproof; install in a dry location.

Certifications

CE, RoHS, FCC Part 15. EMC tested to CISPR 25 (automotive). Suitable for use in research and development settings, but not for safety-critical production systems without additional qualifications.

Conclusion

The ETAS ES600.2 PLC module bridges the gap between desktop simulation and real hardware, enabling rapid validation of control algorithms. Its versatile I/O and real-time capabilities make it a valuable tool for automotive and industrial control developers.
