5.4.4 ES910.3-A for fast application access with INCA-MCE
Fig. 5-11 Test Bench System with ECU access in real-time
With the fast test bench connection for automated measurement and calibration
tasks INCA-MCE (Measurement and Calibration Embedded) developed by ETAS,
an automation system can access the ECU in real-time via the ES910.3-A proto-
typing and interface module.
Partial functions of the INCA application tool were relocated to the real time-
capable ES910.3-A hardware.
The measurement and calibration privileges from the automation tool are then
no longer carried out via ASAP3/ASAM MCD-3 MC, but via EtherCAT, a real
time-capable, Ethernet-based fieldbus, or iLinkRT
TM
, a heavily simplified variant
of XCP-on-Ethernet.
The application mechanisms, such as converting the data exchanged between
test bench (physical) and ECU (hexadecimal), are carried out on the real-time
operating system of ES910.3-A.
Due to the fast access via INCA-MCE, functions such as those for component
protection (e.g. knock controller and exhaust gas temperature monitoring) or
virtual sensors (e.g. air-mass sensor, torque model and exhaust gas temperature
sensor), which are often not yet available in the ECU during the early develop-
ment phases, can be moved to the automation software of the test bench com-
puter.
For additional information about the application access via EtherCAT as Ether-
CAT slave device see chapter 4.11.3 on page 35 and the INCA-MCE User's
Guide.
For additional information about the application access via iLinkRT, see chapter
4.12.4 on page 39 and the INCA-MCE User's Guide.
