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.

Operating conditions
The operation of the assembly group can take place only on condition of observing the required voltage and
the ambient conditions. The operating position of the device is irrelevant. The device is meant to be used in
dry and dust-free areas. Should condensed water build up, an acclimatization period of at least 2 hours must
pass. Assembly groups and components do not belong into the hands of children!
The building group can be operated only under the supervision of an electrically skilled person.
