Overview of functions

Operating modes

The Automotive Ethernet interfaces can be configured in the following operating modes:

  • Communication with BR_XETK

  • Ethernet Monitoring and active protocol communication

Ethernet switch

The integrated Ethernet switch is used for connecting the ES600.2 module and additional measuring or interface modules to a user PC. The data acquisition of the connected modules is done synchronized (Overview of functions). The Ethernet switch can be cascaded with additional network modules so that you can also build larger blocks of measuring and interface modules.

The switch is equipped with a host connection (Fast Ethernet), a host connection (Gigabit Ethernet) and six Ethernet connections (10/100BaseT Ethernet).

All connections of the switch, except for the Ethernet connections "ETH1" to "ETH6", are electrically isolated from each other and from the power supply.

"FE-HOST" host connection

The upstream "FE-HOST" Ethernet interface connects the ES600.2 module with the user PC or the downstream Ethernet interface of another module. This interface enables the ETAS software tools to access the connected modules.

"Wake-Up" function

The "FE-HOST" Ethernet interface supports the Overview of functions.

"GE-HOST" host connection

The upstream "GE-HOST" Ethernet interface connects the ES600.2 module with the user PC or the downstream Ethernet interface of another module. This interface enables the ETAS software tools to access the connected modules.

Ethernet connections "ETH1" to "ETH6"

The ES600.2 module provides six downstream Ethernet interfaces for additional modules. The Ethernet interfaces "ETH1" to "ETH6" are based on the 10/100BaseT standard and can be operated with 10 Mbit/s or 100 Mbit/s, half duplex or full duplex. The switchover is done automatically to the highest possible connection speed.

ECUs that are equipped with an XETK or feature a separate Ethernet interface can be connected directly to the module and communicate with the application software via XCP-on-Ethernet.

Module compound

The connections "ETH1" to "ETH6" connect the ES600.2 module with additional ES600 modules, measuring modules, calibration modules and rapid prototyping modules. The cascadability also allows implementing larger blocks of measuring and interface modules.

Power supply of connected modules

The ES600.2 can also take on the power supply of connected ES4xx modules and ES6xx modules via the Ethernet connecting cable. Observe the maximum output current at the Ethernet interfaces when cascading the modules.

Other modules connected via Ethernet cable must be cabled separately with the power supply.

"Wake-Up" function

Time synchronization

To synchronize the measuring channels in a module compound, the modules of the system provide a global time clock.

Modules connected to the "FE-HOST" interface can synchronize the ES600.2 (SYNC-IN). If no synchronization signal is received at the "FE-HOST" connection, the ES600.2 automatically takes over the function of the master module for the synchronization.

The time synchronization unit of the ES600.2 master synchronizes the connected modules via Ethernet lines. At the connections "ETH1" to "ETH6", the synchronization signal is passed on to connected modules (SYNC-OUT). The slave modules adjust to the cycle specified by the master module.

A phase shift of the individual measuring signals to each other is ruled out, even if the measured values are acquired from different modules.

The data of all connected modules of the series ES4xx, ES51x, ES6xx and the XETK are acquired synchronously (ETAS device synchronization).

The ES600.2 provides a fail-safe bypass function for the Automotive Ethernet interfaces AE1 to AE4. Two integrated relays ensure that communication between connected nodes is maintained even when the device is powered off. Due to fast relay switching and link re-establishment, ongoing communication is typically not interrupted. The actual behavior depends on the link recovery characteristics of the connected nodes.

Relay mode also allows decoupling of the measurement hardware from the system under test without rewiring. This enables temporary exclusion of any influence of the measurement setup on the communication between the ECUs.

"Wake-Up" function

If the system is used in a vehicle, the energy consumption must be as low as possible since the measuring setup is supplied by a battery. For this reason, the ES600.2 module is equipped with a link signal detector at all connections for automatic power-save function.

With the "Wake-Up" function, the module can automatically switch between the operating states "Standby" and "On".

The ES600.2 and modules connected to it automatically switch to the "Standby" operating state if no connection receives any link signals any longer or the host computer is switched off or disconnected. As soon as at least one of these connections receives link signals or the host computer is activated again, the module automatically changes to the "On" operating state ("Wake-Up" function) and automatically switches on all ETAS modules connected in the measuring system.

Note  

The automatic switch-on of the ES600.2 via the "Wake-Up" function is possible at all Ethernet connections.

Note  

For a connected PC to send link pulses, its Ethernet adapter must be configured accordingly.
