ES910.3-A - User’s Guide 40
ETAS Functional Description
Connecting the Test Bench Computer
The ECU interface and the test bench computer with iLinkRT
TM
interface are con-
nected with the CBE200 cable.
4.12.5 "External Switch with ETAS Modules" Operating Mode
At an external switch connected to the ECU interface, it is possible to operate not
only several ECUs or several XETKs in rapid prototyping or MC applications, but
also additional ETAS modules in MC applications.
For additional information about the use of INCA-MCE, see chapter 5.4.4
on page 55.
4.12.6 Feature
You can find a list of applications supported by the ES910.3-A at the ECU inter-
face in chapter 7.6.2 on page 78.
4.13 Extension Slot
The ES910.3-A has a slot for add-ons (Extension slot). Currently, an ES920.1 Flex-
Ray module or an ES921.1 CAN module can be used.
4.14 NVRAM
Typically, diagnostic data (error states or the last operational states) are stored in
non-volatile RAM (NVRAM). Data to be retained during a loss of power or a
power-on cycle can be stored in this memory. This data can be read out and
analyzed the next time the module is launched.
NVRAM supports cold-start measurements and self-learning algorithms. There
are 32 kBytes of NVRAM in the address space of the main processor of the
ES910.3-A.
For more information on the NVRAM, refer to the INTECRIO documentation.
4.15 Watchdog
The OSEK operating system of the ES910.3-A enables the realization of a User
Watchdog function by software. This enables advanced security concepts to be
implemented easily in the rapid prototyping system.
The watchdog function is run in a proprietary independent process and periodi-
cally monitors the RTA-OSEK application in which the simulation model runs.
The user can adapt the watchdog function to suit the requirements of the simu-
lation model.
For more details, consult the INTECRIO documentation.
The operation of an external switch at the ECU interface with daisy chain mod-
ules is supported starting with HSP V9.6.0.
