Introducing the ES581 –

New cost-effective CAN ECU Interface Module coming soon

Sometimes all you need is a compact, simple, cost-effective way to connect your PC with a vehicle’s Controller Area Network (CAN).  That’s exactly what ETAS’ new ES581 CAN interface module delivers—high-quality, high-performance, compact, single-channel interface in a cost-effective package.

The new ES581 connects with a PC over USB, and it’s fully integrated with INCA V5.4 and the upcoming INCA release, V6.0. You’ll get the same advantages you’ve come to expect from ETAS--data from an Electronic Control Unit accurately synchronized with data from external sensors. We’ve electrically isolated the ES581 from the PC so there won’t be any communication drop outs to slow your work.

The ES581 is an ideal tool for a wide range of applications. It can be connected to a vehicle’s CAN port, or diagnostics service port, for powertrain feature or diagnostics calibration. And because it’s integrated with INCA, it’s capable of flash programming an ECU. The ES581 supports J2534, CCP, and XCP protocols, so it’s fully capable for body, driver assistance, and chassis ECU calibration/diagnostics projects too. For vehicle validation, either before or after start-of-production, the ES581 and INCA can read and clear Diagnostic Trouble Codes (DTCs), just like a diagnostic service tool. We’re excited about this newest member of the ETAS ECU interface family, and we’re sure you’ll be too.

The ES581 will be available in October. For more information about the ES581, please contact ETAS at sales@etas.us.

Measurement of Calibration Data and Process Points

At times, it is useful to know particular calibration settings, under which a recording was made. As an INCA user, you can record the results of a measurement under various conditions. Some times, a suitable measure value is available and easy to record. In other cases, an image of the calibration value as a measurement variable may not be available. In such cases, using a special INCA setting, it is possible to record a calibration in INCA.

To record calibrations along with measure variables, proceed as follows:

1. Go to the INCA main page and under Options -> User Options, select the tab "Experiment"
2. Under Options -> Calibrations, click on the right side (under Value)
3. Once in “Change in Calibration Options”, under General Options, select “CalibrationRecording”
4. Set “Enable Measure Calibration devices ” to “Yes”. This setting will enable values to be recorded in a file.

Once enabled, a second entry for each ECU device is displayed in the variable selection dialog: The regular one with the “device name” and a second, virtual device, named “Device name”+#MeasureCal. To measure calibrations you will need to select the calibration value from this second device.

Measurement of calibration data and process points:

• Measure/record all calibration variables just like normal measurement variables:
  • In the experiment environment
  • As input for calculated signals
  • Online (via ASAP3)
  • Offline (via ASAP3/MDF-file).

For curves/maps, INCA calculates and records the interpolated process point.

The New Variable Selection Window

In the upcoming INCA V6.0 the Variable Selection Window has a brandnew look and feel:

• A complete redesign provides significant usability improvements, especially when it comes to handling large variable lists
• A visual raster fill indicator - the indicator is updated every time a variable is added (see Figure 4 below)
• Variables displayed in a raster matrix
• Assigning variables to display windows is much easier
