2. PRODUCT OVERVIEW ECO AND EC GATEWAYS
The ESERA EC and ECO gateways of the latest generation are divided into different series.
We offer the right device for different requirements and areas of application, such as private, commercial and
industrial use.
The following is an overview of the ECO and EC gateways.
All gateways have an access point and web server. Only the gateways with this equipment will be discussed
in this manual. In the following overview, the devices for this manual are marked in green.
For the gateways without web server and access point use the manual version 1.0.

3. MODBUS/TCP GENERAL
Modbus/TCP is a protocol for communication between devices in a network, based on the Modbus protocol
and the TCP/IP protocol.
Modbus is a serial-based protocol that is widely used in industrial automation to transmit measurement data,
control commands, and status messages. It is
also widely used in computer network technology and is used to connect devices in a network.
The Modbus/TCP protocol allows to connect controllers and gateways in Ethernet networks by embedding
Modbus data packets into TCP/IP data packets. It uses the standard port number 502.
The protocol works with two types of packets: Requests and responses. A request is sent from one device to
another to retrieve data or send commands. The response contains the data or confirmation that the
command has been executed.
It also supports various functions, including reading and writing data registers, reading input registers, and
reading and writing lock bits.
Modbus/TCP provides an effective and reliable way to exchange data between different devices on a
network and is used in many different applications in industrial automation, building automation and other
fields.
4. MODBUS COMMUNICATION ECO GATEWAY
Modbus is de facto the common bus standard for communication between PLC machine controllers and the
machine-related environment in industry.
No PLC controller on the market can do without this bus interface. The success story of the Modbus
standard was initiated in 1979 by Gould-Modicon for communication with its programmable logic controllers.
In the industry, Modbus has become a standard because it is an open protocol. Since 2007, the Modbus
TCP version has been part of the IEC 61158 standard. (Source: https://de.wikipedia.org/wiki/Modbus)
ESERA has Modbus/TCP and Modbus/RTU as an integral part of the data interfaces of the ECO Gateway
product series, and can thus connect various industry standards, such as Modbus, MQTT, LoRaWAN, NB-
IoT and 1-Wire, via gateways.
During the development of the ECO sensor gateways, special emphasis was placed on user-friendliness and
many automatic functions. This is additionally supported by a configuration software,
Config Tool 3, which combines all desirable functions up to the documentation and an installation report.
By the ESERA gateways are intended for a wide range of applications, even far outside the industry
attractive. The application areas include all commercial applications, such as smart home, smart building,
data center, OT and IoT systems.

5. ECO GATEWAY SYSTEM
Many sensors, a powerful interface, a web server and access point, and a fully automated plug and play
system.
6. The ESERA ECO Gateway Concept
•A large number of sensors can be connect fully automatically via Industrial 1-Wire Bus
using Auto-E-Connect.
•Up to 30 sensors with a maximum of 150 sensor values can be connected.
•In addition, there are direct analog and digital inputs of the ECO Gateway.
•Furthermore, there is a housing interior climate monitoring system with alarm system.
•Extremely powerful data interface for up to 5 simultaneous data connections to control rooms and
PLC controllers
•Modern settings of the gateway via web server
•Connectable access point for independent access by mobile devices, such as smartphones, tablet or
laptop.
7. INTERFACE (MAXI INTERFACE) - AND I/O SECTION
The basic structure of all ESERA ECO gateways is such that the devices consist of two sections.
The first section consists of an I/O gateway (1-Wire bus, eBus and/or sensor unit) and
the second section consists of a very powerful interface. This very powerful interface is referred to below as
the Maxi Interface.
The two sections communicate with each other internally.
These two sections are built into separate, electronic units on a gateway basis.
The advantage is that each of the sections is specially optimized for its task. This gives you an extremely
powerful, robust device with low energy consumption. The
ECO gateways are designed for years of use.
No Linux system is used in either of the sections. All sections of the devices are natively programmed and
thus very low-maintenance.
The advantage here is clearly the years of use without any update.
Depending on the ECO gateway, different I/O functions, e.g. 1-Wire or eBus and different
interfaces, e.g. Ethernet, WLAN, NB-IoT, LoRaWAN, are available.

8. CONFIGURATION MODBUS INTERFACE
NOTE
The following description is intended for ECO Sensor Gateways from year of manufacture 2023 with
web server and access point. If you have a 1-Wire gateway without web server, please use the
interface manual Modbus V1.0
8.1. ACTIVATE ACCESS POINT The ECO Gateways with Maxi interface have a connectable
WiFi (WLAN) access point.
This means that you can access the device via mobile end
device, such as smartphone, tablet or laptop. This is possible
directly - without additional devices via WiFi (WLAN), access
point (e.g. Fritzbox).
What is an access point?
With an access point (wireless LAN AP mode), mobile end
devices such as laptop, tablet, smartphone, etc. can be
connected directly to the ECO Gateway. No additional
wireless LAN access point is required.
When the access point is activated, we talk about the AP
mode of the WLAN interface of the ECO Gateway.
(See figure, LED "AP" is on, LED "Station" is off)
If you no longer need the access point, switch it off by
pressing the button again for at least 5 seconds.
Push button to activate the Access Point
NOTE
You activate the access point by pressing
(of 5 seconds length) on the button on the top.
The access point is active for approx. 30 minutes. After
that, it deactivates automatically for security reasons.
You can switch off the access point by pressing the
button again for at least 5 seconds.
NOTE
The web server is continuously available via the
Ethernet interface. You can reach it via the
IP address of the device.
The IP address of the ECO gateway can be found on
the "Ethernet Interface Settings" web page
Access Point is activated

8.2. SELECT ACCESS POINT
The ECO gateway with Maxi interface registers as a WLAN access point with the identifier "ESERA". In the
delivery state, the Ethernet interface is set to "DHCP".
The access point is open, without an access password.
8.3. CALL WEB SERVER VIA WIFI
If you have connected to the WLAN network "ESERA", the web browser starts directly on many mobile
phones.
If this is not the case, switch to your web browser (e.g. Firefox, Chrome, etc.) and enter the IP address of the
ECO Gateway. Now the web server of the ECO Gateway should be visible, comparable to the following
picture.
The configuration of the device is currently only possible via
the web server of the ECO Gateway.
NOTE
The IP address of the ECO Gateway via Access
Point is: 192.168.4.1
The IP address of the access point is printed on the
right side of the gateway housing.
Important:
Enter the IP address without "https://".
Select "ESERA" Access Point
NOTE
The ECO WLAN access point can be found as a
WLAN network at the identifier "ESERA".

8.4. CALL WEBSERVER VIA LAN
You can also connect the web server of the ECO Gateway at any time via LAN interface using the set
Reach IP address.
The IP address of the ECO Gateway is shown on the device display (if the device has a display). If the
device does not have a display, you can
also read out the current IP address (not the
IP address of the access point) via your router/access point/DHCP server.
8.5. WEBSERVER, SIGN IN/LOG IN
Password, Sign in/Log in
To be able to log into the web server of the ECO
Gateway, use for the first login the
Startup/default password: eserapwd
For security reasons, the password is not displayed in
plain text, but with dots.
After entering the password, click on the "Log in"
button to open the main menu (hereinafter referred to
as the main menu).
Please change the password after the first login,
otherwise unauthorized persons can also make
settings on the
ECO Gateway.
Please enter a new and secure password via the
main menu/"Change Password".
Advice on how to assign secure passwords can be
found on the Internet.
Software version Ethernet interface/Log Out
Click on the "Log Out" button to exit the web
interface.
NOTE
The startup/default password for Log In is: eserapwd
