1 PRODUCT DESCRIPTION

The ECO 501 gateway represents a powerful sensor interface of the latest generation for machine, plant and

system monitoring. The gateway has an access point and web server.

Up to 30 sensors can be connected to the ECO 501 fully automatically via Industrial 1-Wire Bus using the

Auto-E-Connect Plug and Play system.

The ESERA Auto-E-Connect system, which is an extension of the 1-Wire Bus standard, has been registered

as a European patent by ESERA GmbH.

A wide range of sensors is available, such as temperature, humidity, dew point, air quality (CO2, VOC or fine

dust), digital alarm signalling contacts, glass breakage and smoke detectors.

The ECO 501 provides for configuration, software updates, sensor and production data of the connected

sensors conveniently via web server. The web server is accessible via LAN and the access point (activation

at the push of a button).

This system represents a low maintenance industrial device as no Linux is used. The gateway has been

programmed natively for many years and no unknown libraries are used.

Each of the maximum 30 sensors can supply up to 5 measured values and a total of up to 150 sensor data

to your control system or PLC.

Extensive software support

is available free of charge via Config Tool and ECO Dashboard 100.

Via WLAN and LAN interface it is possible to communicate with up to 3 data connections via Modbus/TCP,

MQTT, ASCII text protocol.

For reliable operation in an industrial environment, the gateway is supplied with 9-30VDC DC voltage.

3 ECO GATEWAY SYSTEM

Many sensors, powerful interface and access point

4 The ECO Gateway concept has the following key points

•A large number of sensors can be

taught-in 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 limits and alarm system

•Extremely powerful data interface for up to 5 simultaneous data connections to control rooms and

PLC controllers

•Modern settings of the device via web server

•Connectable access point for independent access by mobile devices such as smartphones, tablets

or laptops.

5 INTERFACE / INTERFACE AND 1-WIRE SECTION

The basic structure of all ESERA ECO gateways is such that the devices consist of two sections.

These sections consist of an I/O section / gateway (1-Wire bus, eBus and/or sensor unit) and a very powerful

interface, hereinafter referred to as 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 unit with low energy consumption. The

ECO Gateway are designed

for years of use.

No Linux is used in either section. These sections are natively programmed and

thus very low-maintenance. The advantage here is clearly the years of use without updates.

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.

6 ECO GATEWAY CONSTRUCTION

DATA INTERFACE

The ECO Gateway has an Ethernet interface with 10/100Mbit speed.

Various data protocols are supported via TCP/IP or UDP.

Up to 3 data connections and protocols + web server can be used simultaneously.

MODBUS PROTOCOL

The Modbus/TCP addressing of the gateway is clearly structured comparable to many other Modbus

systems. Addresses for system and device data are available.

We provide an address overview with all available data points via the download area of our website and

within the configuration software ESERA Config Tool 3.

MQTT PROTOCOL

Art. No. 11607-24

*If the sensor or actuator supports Auto-E-Connect. For details, refer to the operating instructions of the sensor or actuator.

Subject to technical changes.  ESERA GmbH 2023

www.esera.de 11607-24 V1.0 R1.2 Manual Page 5 from 21

An MQTT data connection is provided for OT and IoT applications. MQTT data is sent and received to a

broker.

You can set the send interval via web server. The sensor name is taken from the name field of the 1-Wire

sensors. If these are empty, default names are used. If you do not want an MQTT protocol, an additional

Modbus data connection can be provided via firmware update. Please ask for this at supp[email protected].

ASCII TEXT PROTOCOL The ECO 501 gateway outputs the 1-Wire sensor data ready prepared, e.g.

for temperature sensors

in C° cyclically. It is only necessary to divide by 100.

In addition, the article number for ESERA modules can be entered, the calculation and output is

adapted to the function of the module.

SENSORS AND ACTUATORS

Up to 30 sensors can be connected to the ECO 501 sensor gateway fully automatically via industrial 1-Wire

bus using the Auto-E-Connect Plug and Play system. Each of the maximum 30 sensors can supply up to 5

measured values and a total of up to 150 sensor data to your control system or PLC.

SELF-SUFFICIENT MANAGEMENT

The Sensor Gateway is intended for the autonomous management of a 1-Wire network. You no longer

need to worry about 1-Wire commands or formulas for evaluating the 1-Wire devices. The ECO 501

PRO gateway independently scans the 1-Wire network for new 1-Wire devices, reads their Auto-E-

Connect data, automatically adapts the device libraries* and outputs the adapted data in plain text,

adapted to the scanned 1-Wire devices.

DESIGNED FOR ALL 1-WIRE NETWORKS

The 1-Wire interface of the ECO 501 PRO is specially designed to

safely operate small to very large

1-Wire networks with long cable distances. 1-Wire devices can be operated simultaneously in mixed

parasitic or normal mode.

The strongest 1-Wire interface currently available has been developed for maximum data security,

even for complex network structures.

VOLTAGE SUPPLY

For power supply the ECO 501 has a wide range input of 12-24VDC (9-30 VDC) and is thus intended

for worldwide voltage system supplies.

Suitable DIN rail or plug-in

power supplies can be found in our webshop.

COMMISSIONING

Support videos for commissioning and configuration can be found on our website www.esera.de under

"Service and Support", Support Videos.

7 AUTO-E-CONNECT® SUPPORT

The ECO 501 PRO 1-Wire gateway supports Auto-E-Connect Level I, II and III.

8 AUTO-E-CONNECT SYSTEM

With the launch of ECO Gateway, the ESERA Auto-E-Connect® 1-Wire Plug and Play system for the

1-Wire bus is now introduced and supported.

This means that fully automatic configurations of the 1-Wire devices* (sensors and actuators) are now

possible on the

1-Wire bus possible. It is optimized for commercial and industrial applications and enables significant

added value beyond sensor and chip data.

The Auto-E-Connect function is built up in three levels. The following levels are currently available

Level I, Level II and Level III are available.

With Auto-E-Connect Level III, fully automatic configurations of the 1-Wire devices on the

1-Wire bus is possible. It is optimized for industrial and IoT applications and enables significant added

value beyond sensor and chip data.

The Auto-E-Connect function automatically detects ESERA devices, starts suitable libraries and outputs

ready-formatted data.

The Auto-E-Connect functionality will be available for the ECO Gateway and ESERA-Station 200 Pro

from 2021.

Auto-E-Connect Level I

OWD Detect: Detect new sensors* and actuators* and automatically start customized libraries

Auto-E-Connect Level II

Visualization of product data: Readout and visualization of Auto-E-Connect and manufacturer data of

sensors* and actuators*, such as part number, date of manufacture, firmware and hardware version.

Auto-E-Connect Level III

Advanced Plug and Play System for 1-Wire Bus

oPRE CONFIGURATION

The OWD number for the next installation can be written to the 1-Wire device*.

oAUTOMATIC POSITIONING

The device* logs on to each ECO gateway with Auto-E-Connect III with the new desired OWD number.

This automatic login works up to the maximum possible OWD number of the ECO gateway.

oSENSORFINDER FUNCTION

The ECO 501 PRO can activate a status LED within the ESERA 1-Wire Pro sensors*. The status LED

flashes or lights up permanently for a certain time. This makes the detection of a device in a 1-Wire

network much easier. A faster detection saves a lot of time and therefore money when searching for a

1-Wire device.

oCLASSES ASSIGNMENT

ESERA 1-Wire Devices are assigned to OWD classes with the same properties. This assignment

enables fully automatic visualization and data evaluation in control systems. A class list is available from

ESERA.
