ETAS
While the ES910/ ES920 modules are used for accessing ETK, XETK, FlexRay,
CAN and LIN, the ES930.1 module allows simultaneously accessing analog and
digital I/O signals. In the process, sensors and actuators are controlled and
analyzed directly by the function model. Simulink®, ASCET-RP or C-code mod-
els can be used as function model.

Configuration and Data Acquisition
All configurations of the ES930.1 module can be defined for each channel in
each case.
The sampling of the signal at the inputs and the output of signals are done
independently of each other, either in a predefined, equidistant time grid or in
the event-triggered mode whose event rasters are defined based on digital
input signals.
The event rasters can be used to synchronously capture all the input data and
initiate model triggers in the rapid prototyping module.

Properties
Overview of the most important properties of the ES930.1:
3.2.1
Decentral cabling Concept
Communication with the PC via an XCP-based protocol that is compatible with
the existing ETAS Ethernet topology. The concept meets the following require-
ments:
•
High bandwidth to be able to capture measured values with high resolu-
tion and high sampling rates,
•
Low transfer times for applications in the function development,
•
Exact synchronization possible with other measuring systems,
•
Simple application based on the Ethernet integration in INCA, no compli-
cated settings of bus parameters
3.2.2
Inputs and Outputs
The following inputs and outputs are available:
•
4 thermo inputs
•
8 analog inputs
•
4 digital inputs
•
4 analog outputs
•
4 sensor supplies
•
6 digital outputs, which also provide the control signals for the half-
bridge switches
•
6 half-bridge switches with current measurement
