ESX.3xm

Midsize Expandable Controller Module

A freely programmable robust controller module built for expansion and customization

Overview

The ESX.3xm is a highly customizable control unit from STW built for use in harsh mobile applications. This controller provides up to 65 software-configurable inputs and outputs due to the modular design. With 14 different expansion boards to choose from, this off-highway rated controller is ready to meet the needs of any mobile machine OEM at any scale. It also supports a multitude of programming environments such as C, logi.CAD, CODESYS, and MATLAB.

Communication

4 CAN interfaces for users of J1939, CANopen, and any other CAN protocol.

Connections

The base version, with 23 inputs and outputs, provides 4 CAN interfaces and 1 RS232 serial interface. Additional CAN or RS232 interfaces, as well as other communication interfaces like USB or Ethernet can be added easily.

Processing

The processor system of the ESX.3xm, based on the powerful TriCore TC1796 from Infineon, is clocked at 150 MHz and is backed by 4 MB of RAM and 6 MB of Flash. A buzzer for audio alarms, and system and user LEDs for diagnostics help troubleshoot the system without the need for any special software tools.

Programming

The ESX.3xm is freely programmable in CoDeSys (version 3.x), in the ‘C’ Language, or with a Matlab/Simulink support package. All of the inputs, outputs and communications ports are fully accessible and configurable through extensive BIOS libraries.

C with API Library (SIL2 safety features available)
CoDeSys v3 (SIL2 safety features available)
Matlab/Simulink

Design

The system is designed for safety-related applications according to SIL2/ISO 61508. Safety features are controlled by a separate, independent microcontroller. Safety functions are available both in CoDeSys and in the C programming language. A complete safety manual is available along with the extensive help files that fully document the ESX.3xm hardware and software.
