Configuration and Communication with 1-Wire Gateway 10
The 1-Wire Gateway 10 has extensive configuration and formatting options, which can be read out and
operated with the ESERA Config Tool 3.
Since communication between 1-Wire Gateway 10 and Config Tool 3 takes place via the open ESERA ASCII
text protocol, you can also exchange data with any terminal program (e.g. Hercules or Putty) at any time via
UDP / RTU with the 1-Wire Gateway 10 and carry out the configuration.
Details about the communication commands can be found in the document "Programmer's Guide" in the
download area of the article on our website, www.esera.de and within Config Tool 3.

Communication
15.1
ESERA ASCII Text Protocol / Programming Manual
The 1-Wire Gateway 10 provides two protocols. The ESERA text protocol in ASCII format can easily be used for
configuration and analysis. Special attention has been paid here to good legibility and traceability for people. 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 open and documented. The current version of the programming manual
can be found in the article download area of our website and via the configuration software ESERA Config Tool 3.
15.2
Modbus Protocol
You can communicate with the 1-Wire Gateway 10 without switching over the ESERA Text or Modbus RTU
protocol. The IP address and the port for the communication can be freely selected. The default settings are Port
5000 and DHCP operation.
The Modbus protocol has a standardized structure.The following is a small excerpt of the addressing overview.
The complete addressing overview can be found in
