1-Wire Gateway
In addition to the Embedded Computer, the ESERA-Station 200 has an extremely powerful and reliable 1-Wire
interface, the 1-Wire Gateway developed by ESERA.
The 1-Wire Gateway is internally connected to the Embedded Computer by serial interface. Via an USB slave
interface, the 1-Wire Gateway can also be accessed directly, without an Embedded Computer. Once you use the
USB interface, the internal communication to the Embedded Computer is interrupted. The Embedded Computer
is only able to receive data.
Standard Modbus TCP protocol
You can work with your industrial controller, e.g. SPS to communicate with the 1-Wire Gateway 20 via
standard Modbus TCP protocol. The addressing is structured in a way that is comparable to many other
Modbus systems. Addresses for system and sensor or actuator data are available.
An address overview with all available data points is available at the article download section of our website.
Independent administration
The ESERA-Station 200 is intended for self-sufficient management of 1-Wire networks. You no longer have
to worry about 1-Wire commands or formulas for evaluating sensor data. The ESERA-Station 200
independently scans the 1-Wire network for new sensors and actuators and makes them available, in plain
text by using Modbus protocol, depending on the modules found and the corresponding data converted.
Formatted data output
The ESERA-Station 200 provides plausibility checked sensor and actuator data in a ready to use format. E.g.
temperature sensor provides values in Celsius degrees with 2 decimal places. You only need to divide this
number by 100. Within the 1-Wire Gateway a product specific transformation table is available for all 1-Wire
sensor and actuator products offered by ESERA.
Designed for all 1-Wire Networks
The 1-Wire interface of the ESERA-Station 200 is specially designed to securely support all sizes of 1-Wire
networks, even for huge cable length. 1-Wire sensor devices can be operated in parasitic or normal mode at
the same time.
The latest available most powerful 1-Wire interface for a maximum level of data security has been used. This
includes complex network structures as well.
1-Wire Gateway configuration
Free configuration software (Config-Tool 3) is provided. When using Config-Tool 3, the latest documentation
is available at any time hence it automatically updates via internet. This software is available for
our webpage. Communication to Modbus TCP is parallel with no switching.
System time / real time clock
No real time clock with battery buffering available in your system? No problem at all. ESERA-Station 200 is
providing time and date as real time clock including an integrated backup battery. Data plausibility check is
possible at any time.
Power supply
The ESERA-Station 200 is supplied with the industrial 24V voltage.
Connection
Standard connectors are provided for USB and Ethernet connections. All other connectors are designed in
modern screwless push-in technology for rigid and fine-stranded cables with cross sections up to 1.5 or
2.5qmm.
Input voltage for the ESERA-Station 200 is 16
– 30 VDC. Therefore it can be used for 24 VDC (industrial
applications). Appropriate hat-rail mounted power supplies or power plugs can be found in our webshop.

Auto-E-Connect® Support
The ESERA
Auto-E-Connect®
1-Wire Plug and Play system will be used for the
1-Wire Bus supported. This enables fully automatic configurations of 1-Wire sensors
and actuators on the 1-Wire bus. It is optimized for industrial applications and
enables significant added value beyond the sensor and chip data.
