Equipment
Standalone Controller
The 1-Wire Gateway is designed for autonomous management of a 1-Wire network. You no longer need to
worry about 1-Wire commands or formulas to evaluate the sensor data. The 1-Wire Gateway 10
automatically scans the 1-Wire network for new sensors and actuators and provides the corresponding data
in plain text using the Modbus protocol, depending on the modules found.
Formatted data output
The 1-Wire Gateway prepares plausibility-tested sensor and actuator data, e.g. for temperature sensors in
C° with 2 decimal places. Only one dividing by 100 is necessary. Within the 1-Wire Gateway, product-
specific conversion formulas are available for almost all 1-Wire sensors or actuators offered by ESERA.
Designed for all 1-Wire networks
Designed for all 1-Wire networks
The 1-Wire interface of the 1-Wire Gateway 10 is specifically designed to handle all sizes from
1-Wire networks, even with long cable lengths, safe to operate. 1-Wire sensors can be operated
simultaneously in parasitic or normal mode.
The currently strongest 1-Wire interface for maximum data security even for complex network structures has
been installed
Configuration of the 1-Wire Gateway 10 Modbus
For the configuration of the 1-Wire Gateway 10 we provide a very powerful and user-friendly software
(ESERA Config-Tool 3) free of charge. Within the software, the complete documentation is always at your
fingertips, as it is automatically updated via the Internet. The software is available via the download area of
the article on our website and via the configuration software ESERA Config Tool 3. Please use only the USB
interface for configuration
System time / Real time clock
You do not have a real-time clock with battery buffering in your system? No problem! The 1-Wire Gateway
10 is happy to provide the time and date. A real-time clock with battery buffering is integrated. This also
allows a plausibility check of the data at any time.
Power supply
For power supply, the 1-Wire Gateway 10 has a power supply input of
9 - 30VDC and is therefore equally suitable for 12V and industry-typical 24VDC supplies.
You can find suitable DIN rail- or plug-in power supplies 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.
Note: Basics and tips for the 1-Wire bus system can be found in the ESERA Online Shop at
1-Wire Basics or see our eBook in the shop under Training / Documentation
