ETAS ES800 - Rapid Prototyping of Software Functions

49 | ES830.1 Rapid Prototyping Module
ETAS ES800 System | User Guide
Digital Inputs and Outputs
The extension connection "I/O" features four digital inputs as triggers or markers
and four digital outputs for indicating system states or events. The function of the
"Power" key on the ES830.1 module can be assumed by an external "Remote
Power" key at the "I/O" connection.
Extensions
The ES830.1 Rapid Prototyping Module can be easily extended:
- with modules from the ES800 series in a module group (stack),
- with an Automotive Ethernet Media Converter ES162.1 at the GE Ethernet
connection,
- with ETAS modules from other series (ES4xx, ES5xx, ES6xx, ES930) via an
ES600.2 switch at the GE Ethernet connection,
- with ETAS modules from other series (ES4xx, ES5xx, ES6xx, ES930) via an
ES88x/ES89x ECU and Bus Interface Module in the ES800 module stack
6.2 Rapid Prototyping of Software Functions
Here, "rapid prototyping" refers to processes that enable early control of the spec-
ifications in near-series vehicles. Early inspection and confirmation of new devel-
opments mean that risks are reduced, the development quality is increased, and
both the development time and costs are reduced.
The modeled software function should be implemented as a prototype. Rapid pro-
totyping systems can be used as an execution platform for the software compo-
nents of these control and diagnostics functions. They are then connected to the
sensors, actuators, and ECUs in the vehicle. These interfaces with the vehicle
mean that the software functions in the rapid prototyping system must be carried
out under real-time requirements as in the ECU.
Rapid prototyping systems are usually real-time computer systems with signifi-
cantly higher computing power than an ECU. Depending on the application, they
can be configured, e.g., with respect to the required interfaces for input and out-
put signals. The entire system is intended for use in vehicles and can be operated
using a PC, for instance. The software functions can be tested and modified
directly in the vehicle. The rapid prototyping model can be executed on the module
without the need to connect a PC.
NOTE
Only one ES830.1 Rapid Prototyping Module can be operated in an ES800 module
stack.
NOTE
The ES830.1 Rapid Prototyping Module must always be operated beneath inter-
face modules (e.g. ES89x) in the module stack. Information on positioning the
module types in the module stack can be found in chapter
13.3 on page 114.
