4 Product features
Standalone controller
The 1-Wire Gateway 11 Modbus is designed to control 1-Wire Networks. You no longer have to worry about
1-Wire commands or algorithms to analyze sensor data. 1-Wire Gateway 11 Modbus scans 1-Wire Networks
by itself in order to identify new sensors or actuator devices. All data found were automatically provided in a
ready to use Modbus protocol format.
Formatted Data Output
1-Wire Gateway 11 Modbus 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 most of our
selling 1-Wire sensor and actuator products.
Designed for all 1-Wire Networks

14 Communication
14.1 ESERA ASCII text protocol
The 1-Wire Gateway 11 Modbus provides two protocols. The ESERA text protocol in ASCII format can easily be
used for configuration and analysis. Particular importance was attached here to good legibility and traceability.
The ESERA text protocol works with "GET" and "SET" commands, which probably every programmer has already
used in his own projects.
The ESERA text protocol is completely disclosed and documented. The current version of the ESERA protocol
description can be found on our website,
https://www.esera.de/shop/software/downloads-firmware-1-wire-controller-1-wire-gateway/
and within the ESERA Config Tool 3 software.
14.2 Modbus TCP protocol
1-Wire Gateway 11 Modbus communication to ESERA text protocol or Modbus TCP protocol is parallel with no
switching. For communication any IP address and any port can be chosen. Default is set to port 5000 and CHCP
mode.
The Modbus protocol is standardized configured. Please refer to the following table for a partial address-
overview. A complete address overview is available for download at the “Programming Manual”at the download
area of the 1-Wire Gateway 11 Modbus.
