4 ECO GATEWAY SYSTEM
Many sensors, powerful interface and access point
5 The ECO Gateway Concept
For all ECO gateways, we have developed and applied a system concept based on our decades of
experience in the development of electronic devices.
THIS CONCEPT CONTAINS THE FOLLOWING POINTS
CONNECTION OF SENSORS
The system concept allows a large number of sensors to be connected via the Industrial 1-Wire Bus using
Auto-E-Connect. This process is fully automatic, which simplifies installation and configuration.
NUMBER OF SENSORS
Up to 30 sensors can be connected to an ECO gateway. These sensors can provide a maximum of 150
sensor values in total.
ANALOG AND DIGITAL INPUTS
In addition to the sensors connected via 1-Wire bus, the ECO gateways also offer direct analog and digital
inputs. This means that other sensors or devices can also be connected directly to the gateway.
CASE INTERIOR CLIMATE MONITORING
The system concept includes a climate monitoring system for the interior of the case. It monitors various
parameters such as temperature, humidity, etc. and has limit values and an alarm system to detect potential
problems at an early stage.
POWERFUL DATA INTERFACE
The ECO gateways offer an extremely powerful data interface that supports up to 5 simultaneous data
connections to control systems and PLC controllers. This allows the acquired sensor values to be transmitted
efficiently in real time.
CONFIGURATION VIA WEBSERVER
The settings of the device can be made via a web server. This gives users a user-friendly interface for
configuring and monitoring the gateway.
ACCESS POINT
The ECO gateways have a connectable access point that enables independent access by mobile devices
such as smartphones, tablets or laptops. This also allows users to access the gateway wirelessly and
monitor and control the data.

6 DEVICE CONSTRUCTION
The basic structure of all ESERA ECO gateways consists of two sections. The following is a general
description of the functions and advantages resulting from the structure.
The description does not apply to all devices, this is a general description about all ECO gateways.
6.1 INTERFACE / SENSOR INTERFACE AND I/O SECTION
The basic structure of all ESERA ECO gateways consists of two sections. The following is a general
description of the functions and advantages resulting from the structure.
The description does not apply to all devices, this is a general description about all ECO gateways.
SECTION I, I/O SECTION/GATEWAY
This section includes the 1-Wire bus, the eBus and/or a sensor unit. It is specially optimized for the
acquisition and communication of sensor information.
The I/O section is designed as an independent, microcontroller-based electronic unit.
SECTION II, DATA INTERFACE, MAXI INTERFACE
The data interface or also called Maxi Interface represents the powerful communication interface of the
gateway. It enables the connection to other systems, control systems or controllers. The Maxi Interface is
also designed as a separate electronic unit based on a microcontroller.
ADVANTAGES OF THE SEPARATE SECTIONS
Below are some of the advantages that result from the device's structure in two sections:
MODULAR EXPANSION OPTIONS
Due to the construction of the device in two sections, extensions and upgrades can be easily carried out.
When a new function or additional module is needed, it can be easily inserted into the appropriate section
without having to replace all the hardware. This allows flexible adaptation of the device to the specific
requirements and needs of the user.
EASY MAINTENANCE AND REPAIR
The modular design also facilitates maintenance and repair of the unit. If a problem occurs in one section, it
can be checked and repaired separately without affecting the functionality of the other section. This reduces
downtime and allows problems to be fixed more quickly.
SCALABILITY AND FLEXIBILITY
The two-section design of the device allows for easy scaling and adaptation to changing requirements.
Different sections with different functions can be combined to meet the requirements of a specific application
area. This makes the device flexible to use and adapt to different scenarios.
SPACE AND COST SAVINGS
Due to the modular design and the possibility of expansion, the device can be used more efficiently. There is
no need to purchase separate devices for different functions, but they can be integrated into a single device.
This saves space and costs for additional hardware.
NATIVELY PROGRAMMED
The sections are natively programmed, which means that they do not rely on Linux or other operating
systems. This contributes to the gateway's low maintenance and enables many years of use without frequent
updates.
SEPARATE CONSTRUCTION
The separate design of the two sections offers advantages in terms of security and operational readiness. In
the event of attempted interference or cyber sabotage attacks on one of the sections, the other section
remains unaffected and operational.

VARIOUS I/O FUNCTIONS AND INTERFACES
Depending on the requirements and the field of application of the ECO gateways, different I/O functions such
as 1-Wire or eBus as well as different interfaces such as Ethernet, WLAN, NB-IoT and LoRaWAN are
available. This allows the gateways to be adapted to different environments and applications.
Overall, the two-section design and associated benefits of the device provide increased flexibility, security,
scalability and efficiency in the use of the device.
Implementation of specific protection measures
In addition, the implementation of specific protection measures in each section of the gateway
provides increased security and protection against potential attacks. Here are some of the protections that
can be implemented in each section of the gateway:
•Secure Boot
Using Secure Boot ensures that only trusted and authenticated software components are loaded
during the boot process. This prevents malicious or unauthorized code from running and
compromising the system.
•Encryption techniques
Sensitive data exchanged between the sections of the gateway can be protected by encryption
techniques. For example, symmetric or asymmetric encryption algorithms are used here to ensure the
confidentiality and integrity of the data.
•TPM modules
Trusted Platform Modules (TPM) are special hardware modules that are used to securely store
cryptographic keys and perform security-related operations. The use of TPM modules can further
strengthen the security functions of the gateway, as they enable the detection of hardware tampering,
for example, and support the secure generation and management of keys.
These protective measures help to increase the security of the gateway and ward off potential attacks. They
ensure the integrity of the system, protect against unauthorized access to sensitive data, and ensure
trustworthy and secure communication between the sections of the gateway. The use of these security
mechanisms minimizes the risk of security breaches and unauthorized access.
Overall, the separate sections, the powerful communication interface and the security measures provide a
robust and flexible system for the acquisition, transmission and backup of sensor data. The use of native
programming and the absence of Linux ensure reliable and low-maintenance use of the ECO gateways over
a long period of time.

"Service and Support", Support Videos.
8 AUTO-E-CONNECT® PLUG AND PLAY SYSTEM
The Auto-E-Connect® 1-Wire Plug and Play system enables fully automatic
configurations of the 1-Wire sensors and actuators on the 1-Wire bus. It offers
various added values and time savings for the customer. The system has been
optimized over many years and is optimized for smart building, industrial applications and IoT.
The Auto-E-Connect system automatically recognizes sensors and actuators and starts suitable libraries.
The data is ready formatted and output. These functions run automatically in the background during the
installation and commissioning of sensors and actuators.
The Auto-E-Connect system consists of three complementary levels that extend the functionality. With these
functions, fully automatic configurations of the 1-Wire sensors and actuators on the 1-Wire bus can be
realized.
Please note that the Auto-E-Connect functionality will be available for the ESERA ECO Gateways and
Station 200 Pro from 2021.
9 SCOPE OF FUNCTIONS AUTO-E-CONNECT SYSTEM
The three levels of the Auto-E-Connect system provide advanced functions and automation for the
installation and configuration of sensors and actuators in the 1-Wire bus.
Below are three levels of the Auto-E-Connect system
Level I
OWD Detect stands for "One-Wire Device Detect" and refers to the function of the ECO gateway to
automatically detect new sensors and actuators and to start adapted libraries within the gateway. This
saves time when connecting a new device to a 1-Wire gateway.
When a new sensor or actuator is connected to the 1-Wire bus, the ECO gateway automatically detects the
new device. It then automatically starts the corresponding libraries which are required for the detected
device.
This function makes the integration of new sensors and actuators much easier, as the manual configuration
effort is eliminated. It saves time and simplifies the installation process, as the gateway independently makes
the necessary settings and adjustments.
OWD Detect thus avoids the time-consuming manual configuration of new devices on the 1-Wire gateway,
which saves time overall when connecting new devices.
Level II
The ECO Gateway offers the possibility to read out and visualize the Auto-E-Connect data and
manufacturer data of sensors and actuators. Various information such as article number, date of
manufacture, firmware version and hardware version can be displayed.
Reading out this data gives you a detailed overview of the properties and specifications of the connected
sensors and actuators. This can help you manage and monitor your 1-Wire devices.
The visualization of the data can be done in different ways, depending on the functions and possibilities of
the ECO Gateway. This can be done, for example, via a web-based user interface or special software
provided by the manufacturer.
NOTE
Basics and tips on the 1-Wire bus system can be found in the ESERA Online Shop at
1-Wire Basics or please refer to our eBook in the store under Training/Documentation.

The visualization of the product data gives you a quick overview of the connected devices and their specific
properties. This can be of great benefit when troubleshooting, maintaining and monitoring the 1-Wire
network.
Level III
The advanced plug-and-play system for the 1-Wire bus offers various functions that facilitate the
installation and configuration of sensors and actuators. Here are some of the functions in detail:
PRE-CONFIGURATION
You can write
the desired OWD number (1-Wire Device Number) for the next installation directly into the sensor or
actuator. In this way, the device itself stores the information about its position in the gateway. This enables
automatic assignment of the devices in the target gateway without the need for manual sorting.
AUTOMATIC-POSITIONING
The device automatically logs on to each ECO gateway with Auto-E-Connect III using the pre-configured
OWD number. This automatic login process works up to the maximum possible number of OWDs of the ECO
gateway. No further configuration is required during commissioning.
SENSOR-FINDER-FUNCTION
The ECO 501 PRO gateway can activate the status LED of a sensor in the 1-Wire sensor network. The
status LED flashes for a certain time to facilitate the detection of a sensor within the network. This enables
faster localization of sensors and saves time and costs.
CLASSES-ASSIGNMENT
ESERA 1-Wire Devices are assigned to OWD classes based on their part number. These classes map
comparable properties, variable names and units. This class assignment enables fully automated software
installation, visualization and data evaluation, both locally and in the cloud. The class parameters can be
output via the data interface, e.g., via MQTT protocol.
These advanced features of the plug-and-play system simplify the installation and configuration of sensors
and actuators in the 1-Wire bus. It saves time and enables efficient management of the devices in your
system.
10 PATENT AUTO-E-CONNECT® SYSTEM

IMPORTANT
It is essential that the module is operated exclusively in accordance with the specified voltages and
ambient conditions.
The operating position of the device is arbitrary, i.e., it can be operated in any orientation.
The installation and commissioning of the assembly may only be carried out by a qualified electrician. A
qualified electrician has the necessary knowledge and skills to ensure that the installation complies with the
appropriate safety standards.
It is also important to perform all connection work on the assembly in a de-energized state. Before starting
any connection work, all power sources should be switched off and appropriate safety precautions taken to
prevent injury or damage.
For more detailed information on the specific operating conditions, I recommend that you read the enclosed
instructions. There you should find all necessary information to operate the module safely and properly.
NOTE
The FE connection (functional ground) of the ECO 501 should be connected to the ground potential (PE) to
establish a functional ground. This is important to ensure reliable operation of the module.
Connecting the FE terminal to ground potential establishes a grounding that helps minimize interference
and electrical problems. Proper functional grounding protects the assembly from electrostatic discharge,
surges, and other potential interference.
It is advisable to follow the manufacturer's instructions and guidelines to ensure that functional grounding is
performed according to the specific requirements of the ECO 501. Also observe possible specifications and
regulations in your specific environment to ensure a safe and reliable installation.

22 DATA INTERFACE, ASCII PROTOCOL
You configure the Ethernet interface with the help of the Windows ESERA program Config Tool 3. You
find this program in the download area of the ESERA Onlineshop Tool 3 software.
23 ESERA ASCII TEXT PROTOCOL
The ASCII text protocol is a communication protocol used to transfer data between different devices via
serial interfaces.
The abbreviation "ASCII" stands for "American Standard Code for Information Interchange" and refers to the
standard code used to represent characters, numbers and symbols in digital form.
In the ASCII text protocol, data is transmitted in the form of character strings, with each character coded in its
ASCII representation. A character string can represent different types of data, such as measured values,
control commands or status messages.
The ASCII text protocol is comparatively simple and easy to implement because it uses the standardized
ASCII character set. Data is transmitted in plain text, which facilitates the readability and traceability of the
transmitted data.
