3 ES400 Product Family

This chapter contains information on the following topics:

• “Wiring Concepts in Test Vehicles” on page 14

• “Features of the ES400 Line” on page 15

• “Housing” on page 16

• “Ports” on page 17

• “LED” on page 19

3.1 Wiring Concepts in Test Vehicles

For the test phase, several hundred sensors must be installed in a test vehicle
in various areas, e.g. in the engine compartment and in the floor area. The sen­sors, which are positioned all over the vehicle, then have to be connected to the
measuring instruments of the test setup.

Today’s standard solutions with their central setup of measuring instruments
inside the vehicle require complex cabling to connect the widely distributed
sensors with the measuring instruments. Numerous, usually long connection
cables between the sensors and the measuring instruments, bundled together
to form several fat wiring harnesses, require a highly modified splash wall of
the test vehicle. This involves long setting-up times as well as high costs.

Fig. 3-1 Central and Decentral Sensor Cabling
With the ES400 modules, ETAS provides a decentral solution which consider-

ably simplifies the test setup of the sensors.

The basic idea of this concept is to install the modules of the ES400 family as
close as possible to the sensors, to concatenate the modules with each other
and to connect just the first module of this chain with the laptop in the vehicle.

ES413.1 - User’s Guide 14

ETAS ES400 Product Family

3.2 Features of the ES400 Line

3.2.1 Advantages of the Decentral Wiring Concept

• The compact ES400 modules can be mounted close to the sensors with
short connection cables.

• The simple assembly and wiring principle (daisy chain topology) of the
modules

– requires only one common cable between the modules for power

supply and data transfer
– considerably reduces the setting-up times for tests
– simplifies the maintenance and the extension of the test setup

• The only item in the vehicle is the laptop which is connected to the mod-

ules with just one cable.

• Test vehicles equipped with an ES400 measurement system can be
used flexibly because the vehicles do not have to be modified for
changed or new test tasks.

3.2.2 Further Features

This list provides an overview of the other features of the ES400 line in addition
to decentral cabling:

• The ES400 modules have a very compact design.

• Each module has an LED for localizing the module.

• The A/D Module with Sensor Supplys of the ES400 family use a XCP­based protocol which is compatible to the existing ETAS Ethernet topol­ogy.

The concept fulfills the following requirements:
– high bandwidth to be able to realize lots of channels with high resolu-

tions (typical in measuring and calibration applications) with fast
sampling rates

– simple application based on the Ethernet integration in INCA, no com-

plicated setting of bus parameters,

– simple to integrate in measurement and calibration tools manufac-

tured by third-party suppliers due to the use of XCP as application
protocol

– support of all probes and pressure sensors used in the automotive

industry

• Innovative, battery-saving power supply management

– automatic power-saving feature (“Standby”)
– “Wake Up” via the Ethernet interface

• Part of the ETAS Tool Suite

• Daisy Chain Configuration Tool (stand-alone operation)

ES413.1 - User’s Guide 15

ETAS ES400 Product Family

• Modules suitable for use in automotive applications; suitable for use in
the development environment and in the vehicle on test drives:

– Housing, connectors and cables waterproof and dustproof in acc.

with IP65 or IP67; designed for use in the engine compartment or the
outside area of the vehicle

– rugged to acceleration or mechanical damage
– rugged to extreme environmental conditions (temperature, damp-

ness, EMC)

– very low temperature coefficients contribute to the reduction in the

number of measurement errors

For the complete technical data of the ES413.1, refer to the chapter “Technical
Data” on page 57.

3.3 Housing

A sturdy metal housing is used for the ES413.1; it has ports on the front of the
device so it can fit into tight spaces. The ES413.1 is specifically designed to be
installed in engine compartment, but also in the passenger cell.

The housings of the ES400 family can quickly and easily be connected to one
another to create a measurement system (see section 5.2 on page 35). The
modules can easily be screwed directly to a carrier system or attached to it
using cable fasteners both in the vehicle and in the lab.

These simple and uncomplicated ways of attaching the modules make them
flexible in terms of assembly. These methods of attachment can also be used
in harsh environmental conditions (salt fog, dirt).

CAUTION

Loss of Features as defined by IP65!

Do not open or change the module housing!
Works on the module housing may be executed only by qualified technical
personnel.

3.4 Ports

The ports of the ES400 measuring modules are on the front of the device (see
Fig. 3-2 on page 17).

Fig. 3-2 Front

The Lemo connectors used adhere to protection class IP65. All ports are
reverse-polarity protected due to the exclusive use of coded Lemo connectors.

3.4.1 Sensor Connection Cable

The front of the ES413.1 features a integrated sensor connection cable to
which four sensors can be connected. An individual sensor power supply port
is available for each sensor.

The ES413.1 is deliverable in three versions with differently assembled sensor
connection cable:

3.4.2 Daisy Chain Ports (“IN”, “OUT”)

The modules are connected using a daisy chain topology. This means each
module has an explicit input socket and an explicit output socket. The Ethernet
data line and the supply voltage are routed through the daisy chain ports of the
module:

• “IN” (input)

• “OUT” (output)

The PC, the modules ES523, ES59x, ES600.2, ES891, ES910.3 or the Drive
Recorder ES720 are connected at the “IN” port (input). The “OUT” port (output)
is connected to the following module of the ES400 line or remains free on the
last module of the chain.

4.2 Block Diagram

Fig. 4-2 Block Diagram
The ES413.1 is a module with four identical sensor channels, two shared Ether-

net interfaces, a power supply and a integrated sensor connection cable.
The integrated sensor connection cable consists of four identical cable sec-

tions in different length to which four sensors can be connected. Each cable
section is assigned to an ES413.1 measurement channel and wired according
to the same scheme.

The ES413.1 is deliverable in three versions with differently assembled sensor
connection cable (see chapter 3.4.1 on page 17).

4.3 Sensor Channels

All sensor channels of the ES413.1 are identical. Every sensor channel consists
of the function groups Signal Processing and Filter as well as Sensor Power
Supply.

4.3.1 Signal Processing and Filters

ES413.1 - User’s Guide 21

Fig. 4-3 Signal Processing and Filters of a Sensor Channel

ETAS Hardware Description

The level of the input signal is limited in every sensor channel after the overvolt­age protection by a capacitively compensated voltage divider. An amplifier
adjusts the input signal to the following analog anti-aliasing filter according to
the selection of the input voltage range.

An A/D converter digitizes the output signal of the analog filter. The individual
A/D converter available in every sensor channel guarantees synchronous sam­pling of the measure signals.

A digital filter then processes the digital signal. The digital filter can be config­ured in the application program. The data is written to a data buffer at the out­put of the digital filter. It can be queried there by the application program.

4.3.1.1 Compensating Group Delay

The group delay is the time it takes the input signal of an analog or digital filter
to pass the filter. In the application program (e.g. INCA MDA), the signal must
be delayed to compensate for the group delay.

A special feature of the ES413.1 is the compensation of the group delay within
the module. The group delays of the analog anti-aliasing filter and the configu­rable digital filter are taken into consideration in this process. The signal in the
application program (e.g. in MDA) no longer has to be delayed to compensate
for the group delay.

4.3.1.2 Setting the Filter

For an overview of the possible settings and details of the technical data of the
digital filter, please refer to section 7.8.5 on page 66.

4.3.1.3 Digital Filter Configuration Recommendations

The -3 dB cutoff frequency of the digital filter system of the ES413.1 can be
configured in the application program.

To avoid aliasing effects, be sure to observe recommendations for the configu­ration of the filter depending on the selected INCA sampling rate. The following
table contains the relevant notes.

4.3.2 Galvanically Isolation

The sensor channels are galvanically isolated from each other and from the
power supply. The digitized transfer of the measurements on an Ethernet con­nection implicitly results in a separation of the sensor channels from the supply
voltage.

4.3.4 Sensor Supply

Every sensor that can be switched to the ES413.1 has an individual sensor sup­ply voltage which can be set separately.

The integrated integrated sensor connection cable transfers both the sensor
supply voltage and the sensor output voltage for the sensor. Additional cables
or an additional external power supply for the sensor supply voltage are not
required.

Fig. 4-5 Sensor Supply for a Sensor Channel

The sensor supply voltage is generated from the module operating voltage in
every sensor channel. The sensor supply voltage can be modified in steps. The
user can switch off the sensor supply voltage of each sensor channel in the
application program or select one of the defined values between +5 V and
+15 V.

With a short-circuit of the sensor supply output against ground, the sensor
power supply of this channel is automatically switched off. Every sensor supply
output is protected against overvoltage. A fuse blows if the maximum value is
exceeded. When a short-circuit occurs and a fuse blows, the application pro­gram receives channel-specific information which can be evaluated.

TIP

The supply voltages of the sensors are not galvanically isolated from the
operating voltage of the module.

4.4 Data Transfer

For data transfer, the ES930.1 as well as the ES4xx and ES63x modules use a
100 Mbit/s Ethernet network connection in duplex operation. The data transfer
can be adapted flexibly to suit the test setup and the measurement task.

TIP

The complete Ethernet bandwidth is available for both measure data and
control variables.
Calibration procedures can take place in a Rapid Prototyping application with­out delay with measure data being acquired at the same time.

4.4.1 Communication Protocols

The universal ASAM measure and calibration protocol XCP is used for serial
communication. On the Ethernet transport and network layer, the UDP/IP pro­tocol is used (see Fig. 4-6 on page 25).

Within the XCP protocol, the modules transfer, among other things, module ID,
time stamp and measure and/or stimulation data in an extremely precise and
predictable time pattern. The communication protocol used for the modules
avoids repeated transfer of protocol data, which takes place, for example, in
handshake-based systems. This makes a high bandwidth available for refer­ence data.

Fig. 4-6 Message Format “XCP on UDP” (Schematic)

Using the UDP/IP standard for data transfer makes it possible to connect the
modules directly to a PC, a router or a switch. In XCP communication, the PC
has the master function.

ETAS

No real-time requirements are made. Data acquisition on a PC, which generally
does not have to fulfil high real-time requirements, can thus be connected
directly to an ES400 chain. With a real-time-capable master, such as, for exam­ple, a Rapid Prototyping system, lots of different kinds of I/O signal can be
accessed with extremely short cycle times.

TIP

The communication protocol used by the ES400 family makes it possible for
third-party suppliers to use the communication protocol for their own, non­ETAS applications once the modules have been configured with the „ES4xx
Configuration Tool from ES4xx_DRV_SW“ .

4.4.2 Realization

4.4.2.1 Time Slice Procedure

The modules in the daisy chain transfer the data to the master using a
100 MBit/s Ethernet connection time-controlled, i.e. without being prompted.
The PC assumes the function of the master. In the network, the modules
respond like a single Ethernet device with one MAC address.

All daisy chained modules have a generator which is only activated in the last
module of each chain after the test setup has been connected to the PC. The
frequency of the generator or the period duration of the time slices generated
can be set in the application program. It corresponds to the measuring fre­quency of the measurement channel with the highest acquisition rate in the
chain.

A binary counter linked to the generator periodically counts the time slices gen­erated (value range: 2
vant number of time slices in the IP header. The Ethernet frames are
transferred from module to module within the chain.

Each module in the chain receives bandwidth to transfer its measure data in
freely selectable time slices assigned within the period of the binary counter.
The module uses the number of the time slice to determine whether it can
insert an XCP message with its measure data into the current time slice.

The fastest module, which determines the period duration of the time slices
generated, transfers data in every time slice. An Ethernet frame then contains
at least one XCP-on-Ethernet data package. The length of the Ethernet frame
transferred inside a time slice increases with the number of modules which can
insert their data into this time slice.

The numbering of the time slices ensures, for example, that two modules which
work with half the sampling rate of the generator never attach their data to the
same Ethernet frame. One module uses only the odd frame numbers and the
other only the even ones. This mechanism also ensures for certain that the
assigned frames do not exceed the length of a time slice.

= 65536). The last module in the chain sends the rele-

The measure data is automatically distributed to the frames so that the avail­able bandwidth is used perfectly.

ETAS

The time slice procedure makes both measurements of fast signals and the
acquisition of a large number of channels with a low sampling rate possible.

If a few fast signals and lots of slow ones are acquired in a chain, the slow
signals can be transferred in time multiplex procedure.

TIP

Due to data transfer by Ethernet, there are virtually no limitations in terms of
the number of modules in a module chain even with fast sampling rates.

4.4.2.2 Clock Generator for Synchronizing Modules

The clock generator for the synchronization of the modules is either the first
module in an module chain or the network module ES600. In both cases, the
measure data is synchronized with a tolerance of one microsecond. Using an
ES600 network module, several ES4xx/ES63x/ES93x chains can be synchro­nized with each other or with the modules of the ES600 series. The ES4xx/
ES63x/ES93x and ES600 modules add the relevant time stamp to the Ethernet
data package for every measure value. The exact assignment in terms of time
of the measure data of the ES4xx/ES63x/ES93x and ES600 modules used
resulting from this makes precise analysis of the correlations of measure sig­nals possible.

4.4.2.3 Synchronizing the Modules and INCA Signal Processing

Data transfer does not require synchronization of the local timebases of the
ES4xx/ES63x/ES93x modules. The time stamps are still synchronized by the
system to be able to correlate measure data and sampling times of different
modules in terms of time after data transfer. A precise time and drift synchro­nization takes place in the modules via a hardware connection.

No bandwidth is required for this, unlike time synchronization in acc. with
IEEE1588 (Precision Time Protocol). The modules add the time stamp to the
Ethernet data package for every measure date.

The combination of time stamp synchronization, full duplex and time slice pro­cedure results in a very high reference data rate of the modules.

4.4.3.1 Example 1

ETAS

Fig. 4-7 on page 28 shows an example of an application with three concatenated ES400 modules with the same acquisition rates. The transfer
scheme for this configuration is shown in Fig. 4-8 on page 28.

In this example, the third module periodically generates 2

(65536) time slices each 100 microseconds long. Modules 1, 2 and 3 acquire measure-

ments with the same rate of 10 kHz each. Module 1, Module 2 and Module 3 link their measurements to each time slice (see Fig. 4-8 on page 28).

Independently of this, control variables can be transferred at the same time from the PC to the modules.
