RA Consulting, headquartered in the asparagus town of Bruchsal, Germany, develops software inspired by people. The IT service provider and tool specialist comes with measurement, calibration, and diagnostic know-how for the automotive industry offering over 30 years of experience through intensive development. The products are used by more than 400 customers worldwide with over 40 000 active licenses in the market. RA Consulting has a global presence with regional offices in Beijing, Detroit and more than 13 sales partners in Europe, North America, and Asia. In 2022, RA Consulting joined CAN in Automation (CiA) as a member.

Generations of RA tools are supporting CAN-based protocols such as Classical CAN, CAN FD, CCP, and XCP, and are scalable to CAN XL and beyond. In addition, they support many other protocols used in the automotive industry. RA tools are modular and are highly-scalable to the latest technological trends and individual needs of customers. Some of the well-known tools includes Diagra D, a specialized diagnostic software providing complete solution for vehicular diagnostic development. Diagra D offers reliable diagnostic functions for the acquisition of high-quality diagnostic data from vehicle ECUs (electronic control unit). It supports Classical CAN, CAN FD, SAE J1939, SAE J1979, and others.

Silver Scan-Tool focuses on 100 % OBD compliance for OBD-II, EBOD, HD OBD, and WWH OBD diagnostics around the world including J1939 and J1979. We offer many other software tools, components, and services to our customers worldwide. Diagra Flash Station is a flashing tool which lets users flash up to 20 control units on separate Classical CAN or CAN FD vehicle networks. In the case of DoIP, the control devices can be operated together in a subnet.

Measurement and calibration tool

Diagra X, a relatively young and modern tool for measurement and calibration tasks with focus on usability joins the RA tools family. Measuring and calibrating ECUs is a complex process, due to frequent changes in ECU software and short time-to-market, poses a great challenge for application engineers to optimally adjust software parameters for the given configuration of the system. Although there are many tools for measurement and calibration tasks on the market, Diagra X stands out for its function-oriented, data-rich, and user-friendly design. Diagra X is developed in compliance with ASAM standards and functional safety is ensured in accordance with ISO 26262. The tool is not limited to automotive applications. Its design and configurable architecture allows it to be used in other application areas using Classical CAN, CAN FD, CCP, and XCP on CAN.

Plug-and-play source connectivity

In a larger project with multiple model variants and multiple stakeholders from different areas such as development, calibration, and validation, there is often the possibility that many different control software and interface hardware being used from different vendors. In such scenarios many of the times setting-up of tool environment and associated hardware interfaces is too cumbersome and confusing to novices. Diagra X's plug-and-play source connectivity and compatibility with a range of interface hardware makes it easier for users to create and share configurations.

The product automatically detects the supported protocols based on the source description files such as A2L, DBC. Today, vehicles are equipped with many ECUs, each of which may have thousands of signals to measure and characteristics to optimize. In many cases, users need to tune these ECUs in parallel to achieve optimal vehicle performance. The Diagra X architecture supports multiple controllers in parallel for measurement and calibration operations, users can also use multiple working pages for each controller. The tool offers a variety of configurable visualizers that are well-suited for low to high-speed, high-performance tasks.

Reusable architecture

Typical users of an MCD tool create an experiment consisting of multiple visualizers to perform measurement and calibration operations. In traditional tools, these visualizers are loosely aligned and can be freely moved around the computer screen. As the number of visualizers increases, it often becomes difficult for the users to find and keep track of the visualizers and variables. Diagra X addresses this typical user pain-point with its grid-based layout of worksheets and well-organized experiments. The users can assign a measurement or a calibration visualizer to a grid or a set of grids, these assigned visualizers are fixed in that worksheet. The users could easily search and find worksheets, visualizers, and variables using the variable monitor.
