Internal communication among 1-Wire Gateway and Embedded Computer
15.1
ESERA ASCII text protocol / programming manual
The 1-Wire Gateway inside the ESERA-Station 200 provides two types of protocols. The ESERA text protocol in
ASCII format easily supports configuration and analysis whereas the ESERA text protocol runs on "GET" and
"SET" commands.
The ESERA text protocol is totally open and documented. The latest version of the ESERA protocol description is
available for download in our webshop
controller-1-wire-gateway/) as well as in the ESERA Config-Tool 3 download area.
15.2
Modbus protocol
ESERA-Station 200 is able to communicate to ESERA text protocol or Modbus TCP protocol with no switching.
For communication any Modbus slave-address (device address) can be chosen. Device address equals the
1-wire Gateway / Controller number. Device address is set to 1 by default.
The Modbus protocol is standardized configured. Please refer to the following table for a partial address-
overview. The entire addressing overview can be found in the programming manual, which can be found in the
download area of this product on our website and by the configuration software ESERA "Config Tool 3".

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 areas
free of dust.
Should condensed water build up within the sensor, an acclimatization period of at least 2 hours must be met. The
components can be operated only under the supervision of an electrically skilled person. Assembly groups and
components do not belong into the hands of children
In industrial facilities, the accident prevention regulations of the federation of industrial professional associations for
electrical installations and equipment must be observed. Do not operate the components in an environment with
inflammable gases, vapors or dusts or in an environment where such gases, vapors or dusts may occur.
