ES920.1
3.2.1
Features
The ES920.1 FlexRay Module, when accommodated in the extension slot of the
ES910 Rapid Prototyping Module, enables rapid prototyping applications at Flex
-
Ray channels.
Together with the ES910, the ES920.1 module is part of a highly efficient, com
-
pact development and experimental platform with high computing and simula
-
tion performance due to the use of a close-to-target, fast floating-point
processor. The AUTOSAR-compatible RTA-OSEK operating system of the ES910
guarantees simple transition from the finished function prototype to ECU soft
-
ware development.
The ES920.1, equipped with the Bosch E-RAY IP, provides a FlexRay node with
the channels A and B which can send and receive FlexRay frames. Interrupts can
be triggered at cycle, segment and slot level.
To optimize system performance, a preprocessor handles the FlexRay communi
-
cation paths independently from the simulation controller of the ES910.
Together with the ES920.1, the ES910 is hardware optimized for rapid prototyp
-
ing applications used to develop FlexRay ECUs.
The ES920.1 is configured entirely in INTECRIO.
Overview of the Major Features of the ES920.1:
• One FlexRay node with two FlexRay channels which can be used redun
-
dantly
– Channels galvanically isolated from each other, from the device
ground and from the supply voltage
– “Wake Up” via FlexRay
• Efficient connection of the ES920.1 FlexRay port to the ES910 simulation
controller
• Use of the BOSCH E-Ray IP Module as a FlexRay Communication Control
-
ler, compatible with the FlexRay Protocol Specification V2.1
• Support of future FlexRay versions with firmware update
• Configuration possibilities in the calibration software:
– Data rates of up to 10 MBit/s
– Max. 128 frames
– 8 kByte message RAM, for example
to save 128 frames with max. 48 byte payload or
to save 30 frames with max. 254 byte payload
– Slot counter filter, cycle counter filter and channel filter
– Network management support
Note
The ES920.1 FlexRay Module can be operated in the extension slot of the
ES910.2 and the ES910.3-A.
