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 18

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 considerably
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.

ES415.1 - User’s Guide14

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 sup-

ply 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 mod­ules 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 High Definition A/D Module with Sensor Supplys of the ES400 family
use a XCP-based 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)

ES415.1 - User’s Guide 15

ES400 Product Family ETAS

CAUTION!

• 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, dampness,

EMC)

– very low temperature coefficients contribute to the reduction in the

number of measurement errors

For the complete technical data of the ES415.1, refer to the chapter "Technical
Data" on page 70.

3.3 Housing

A sturdy metal housing is used for the ES415.1; it has ports on the front of the
device so it can fit into tight spaces. The ES415.1 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 36). 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).

Loss of Features as defined by IP67!

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

3.4 Ports

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

The LEMO and Souriau connectors used adhere to protection class IP67. All ports
are reverse-polarity protected due to the exclusive use of coded LEMO or Souriau
connectors.

Fig. 3-2 Front

3.4.1 “Sensor” Port

The front of the ES415.1 features a 22-pin Souriau port to which four sensors
can be connected using a adapter cable. An individual sensor power supply port
is available for each sensor.

The use of a “cable tail” or “whip” solution with just one connector makes it
possible to change the modules quickly within complex test setups.

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.

4.3 Sensor Channels

All sensor channels of the ES415.1 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

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

4.3.2 Amplifier and analog Filter

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. This 4th order analog filter with Butter­worth characteristics has a cutoff frequency of 50 kHz.

4.3.3 A/D Converter

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.

Sample Rates for Rapid Prototyping Applications

For Rapid Prototyping applications, the sample rate of the ES415.1 module is
limited to a maximum of 10 kHz. The sample rates 100 kHz, 50 kHz and
20 kHz are available only for measurement and calibration applications.

Sample rates to 10 kHz can be configured for measurement and calibration
applications as well as for Rapid Prototyping applications in the application soft­ware.

To avoid the IRQ overload at the I/O port of the ES910.3, the sample rate of the
ES415.1 module in this mode is automatically limited to 10 kHz.

If the ES415.1 would be operated at high sample rates for Rapid Prototyping
applications, the ES910.3 could no longer process the data of the ES415.1 or
other ETAS daisy chain modules due to IRQ overload at its I/O port and would
discard the data.

ES415.1 - User’s Guide 21

Hardware Description ETAS

If the user selects a higher sample rate in this mode (100 kHz, 50 kHz and
20 kHz), the application software prevents the initialization of the hardware and
points to the limited selection of sample rates.

4.3.4 Digital Filter

A digital filter then processes the digital signal. The parameters of the CIC filter
(Cascaded-Integrator-Comb filter) are automatically set upon selecting the sam­ple rate in the configuration software. The digital filter can be switched off,
parameters of the filter cannot be configured.

The data is written to a data buffer at the output of the digital filter. It can be
queried there by the application program.

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 ES415.1 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.

Examples

To represent the group delay with digital filters, a test signal was sent to two
filters of the same type:

• Filter A without compensation of the group delay

• Filter B with compensation of the group delay

The configuration of both filters is identical. The test signal is sampled with the
sampling rate f
quency f

= 200 Hz.

C,CIC

= 2 kHz (0.5 ms). The filter channel was set to a cutoff fre-

S,INCA

Fig. 4-4 and Fig. 4-5 on page 23 show the relevant signal trace - in the upper
part of the figure without a filter, in the lower part of the figures with a filter and
without or with group delay compensation respectively.

4.3.5 Maximum Input and Common-Mode Voltages

The maximum input voltage between two inputs and the maximum voltage
between an input and the case ground is 60 V DC/ 30 V AC. For an explanation

4.3.6 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.

ES415.1 - User’s Guide24

ETAS Hardware Description

Note

4.3.7 Sensor Supply

Every sensor that can be switched to the ES415.1 has an individual sensor supply
voltage which can be set separately.

The cable connected to the sensor port of the ES415.1 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.

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, select one of the defined values between +5 V and +15 V or
enter or define any value within the value range.

Behavior for Rapid Prototyping Applications

The already existing sensor voltage is briefly interrupted at the start of the Rapid
Prototyping model on the ES910.3.

Electrical Isolation

The ground of the sensor supply voltage channels is connected with the ground
of the operating voltage of the module and protected with a fuse.

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

Overvoltage Protection

Each sensor supply output is protected against overvoltages. Exceeding the max­imum value trips a fuse.

Fuses

If a sensor supply output (ground) is connected with the supply voltage (positive)
of the module, it trips a fuse.

Defective fuses cannot be replaced by the user. Please return defective modules
to ETAS. Notes about the process are available from the local ETAS sales and
service offices. The contact information is located in the chapter "ETAS Contact
Addresses" on page 108.

Overload

Upon exceeding the maximum output of a channel, the output voltage of this
channel is reduced.

Short-circuit Detection

In case of a short circuit of a sensor supply output (positive) to ground, the sensor
power supply automatically switches off this channel.

Information in the Application Program

In case of short circuits and tripped fuse, the application program receives ana­lyzable channel-specific information.

can be adapted flexibly to suit the test setup and the measurement task.

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. 4-7 on page 26).

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.

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.

Note

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.

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

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.

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

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.

Note

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.

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.

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.

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.
