1 Product description
Sensors and Actuators
The ECO 208 PRO 1-Wire Controller supports up to 30 sensors, actuators, iButton keys or memory devices
(referred to collectively as Devices in the following). Up to 5 data values can be output per 1-Wire device. This
means that the ECO 208 PRO can provide up to 150 data values, which is a very large number and a very good
price per data value ratio.
Data interface
The ECO 208 PRO 1-Wire Controller has a Modbus TCP and ASCII data interface.
You can communicate with your industrial control system, e.g. PLC, monitoring control and data acquisition
systems (SCADA) via the standard Modbus TCP protocol with the ECO 208 PRO Controller.
Thus, the ESERA ECO 208 PRO equiments provide an optimal interface between modern digital
1-Wire devices and your monitoring system.
Modbus Protocol
The Modbus TCP addressing is clearly structured, comparable to many other Modbus systems.
Addresses are available for system and device data.
An address overview with all available data points is available in the download area of our website and within
the configuration software ESERA Config Tool 3.
Autonomous management
The ECO 208 PRO 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 208 PRO
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 208 PRO is specially designed to safely operate small up to very large
1-Wire Networks with long cable distances.
1-Wire devices can be operated simultaneously in mixed parasitic or normal mode.
The currently strongest 1-Wire interface was developed for maximum data security even for complex network
structures.
Formatted data output
The ECO 208 PRO outputs the sensor and actuator data ready-prepared, e.g. for temperature sensors
cyclically in C°. 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.
System time / real-time clock
You do not have a real-time clock with battery buffering in your system? No problem, the ECO 208 PRO will
gladly provide the time with date. The real-time clock (RTC) is supplied by a maintenance-free goldcap
(super capacitor) for approx. 2 days in the event of a power failure.
What is a gold cap (super capacitor)? You can find an explanation here:
https://de.wikipedia.org/wiki/Superkondensator
Power supply
For power supply, the ECO 208 PRO has a wide range input from -38VDC to -72VDC and is thus intended
for telecommunication typical -48V system supplies.
Suitable DIN rail or plug-in power supply units 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.

2 Auto-E-Connect Support
The ECO 208 PRO 1-Wire Controller supports Auto-E-Connect Level I, II and III.
3 Auto-E-Connect System
With the launch of the ECO Controller, 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. It is optimised 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. Currently there are Level I, Level II and Level III
available.
With Auto-E-Connect Level III, fully automatic configurations of the 1-Wire devices on the
1-Wire Bus are possible. It is optimised for industrial and IoT applications and enables significant added
value beyond sensor and chip data.
With the Auto-E-Connect function, ESERA devices are recognised fully automatically, suitable libraries are
started and ready-formatted data is output.
The Auto-E-Connect functionality will be available for the ECO Controller and ESERA-Station 200 Pro from
2021.
Auto-E-Connect Level I
OWD Detect: Detection of new sensors* and actuators* and automatic start of adapted libraries
Auto-E-Connect Level II
Visualise product data: Readout and visualisation of Auto-E-Connect and manufacturer data of sensors* and
actuators*, such as article number, date of manufacture, firmware and hardware version.
Auto-E-Connect Level III
Extended Plug and Play System for 1-Wire Bus
oPre Configuration: The OWD number for the next installation can be written into the 1-Wire device*.
oAutomatic Positioning: The device* logs on to each ECO controller with Auto-E-Connect III with the new
desired OWD number. This automatic registration works up to the maximum possible OWD number of the
ECO Controller.
oSensorfinder Function: The ECO 208 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. 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 visualisation and data evaluation in control systems. A class list is
available from ESERA.
For further information on the ESERA Auto-E-Connect system, please refer to the ESERA website and the
ESERA Config Tool 3.
Auto-E-Connect is registered by ESERA GmbH as a German and European Patent.

Data interface ESERA ASCII Text protocol
The Ethernet interface is configured with the help of the Windows ESERA programme Config Tool 3, which
can be found in the download area of the ESERA online shop.
12 Configuration und Communication
The ECO 208 PRO has extensive configuration and formatting options which are read out and operated with
the ESERA Config Tool 3.
Since the communication between ECO 208 PRO and Config Tool 3 takes place via the open ESERA ASCII
text protocol, you can also communicate at any time with any terminal program (e.g. z.B. Hercules oder
Putty) via UDP / TCP/IP. to exchange data with the ECO 208 PRO and to carry out the configuration.
Details on the communication commands can be found in the document "Programming Manual", which you
can find in the download area of the ECO 208 PRO and within the Config Tool 3 software.
12.1 ESERA ASCII Textprotokoll
The ECO 208 PRO provides two protocols. For configuration and analysis, the ESERA text protocol in ASCII
format can be used very easily. Here, special emphasis was placed on good readability and traceability. The
ESERA text protocol works with "GET" and "SET" commands, which probably every programmer has used in
his own projects.
The ESERA text protocol is disclosed and documented. The latest version of the ESERA protocol description
can be found in the Programming Manual in the download area of the article and in the ESERA Config Tool 3.
By default, port 5000 is preset for the ASCII protocol.
Note

15 1-Wire Network, Cabling
The special feature of the 1-Wire system is the "BUS technology". All devices (sensors and actuators) are
operated in parallel on a three-wire line, which is used for both power supply and data communication. The 1-
Wire bus system joins the list of other successful bus systems such as CAN or Modbus RTU. All of the installation
principles recommended for these are also applicable and appropriate to 1-Wire.
The maximum size of a 1-Wire Network is determined by various factors. These are mainly:
- Total cable length and cable type
- Number of 1-Wire devices
- Type of cable installation (topology)
- Number and design of cable connectors (unnecessary connection transitions should be avoided)
All factors in total are summarised and referred to as 1-Wire Bus load. Each increase of a factor increases the
total 1-Wire Bus load for the 1-Wire controller and thus reduces the maximum network size.
According to our many years of experience and a lot of feedback from customers, the following conservative
recommendation can be made:
- Maximum cable length 50 -120m
- Number of 1-Wire devices no more than 20 -22 pieces
- As linear a topology as possible without T-junctions
The topology in particular plays a major role. If possible, linear topology should be used. The linear topology can
be compared like pearls on a pearl necklace. The data line should be laid from one device to the next without
T-joints.
Furthermore, the type of cable used can also be mentioned here. We recommend for the cabling
CAT5 or CAT6 network cable. It is also possible to use J-Y(St)Y telephone cables and KNX cables. Longer cable
runs are possible with CAT5 versus CAT7 cables.
With twisted pair cables, a longer connection length can be achieved in an undisturbed environment, as the
capacitive bus load is lower. A total length of 50 m and more can be easily achieved without additional measures.
In disturbed, commercial and industrial environments, the cable should always be shielded in order to increase
the "robustness" or interference sensitivity of the system.
