Modbus Communication 1-Wire Gateway
Modbus is de-facto the common bus standard for communication among PLC machine controls and the machine-
oriented environment in industry.
No PLC control on the market can operate without this bus interface. The success story of the Modbus standard
was launched in 1979 by Gould-Modicon for communication with its programmable logic controllers. In industry,
Modbus has become a standard as it is an open protocol. Since 2007, the Modbus TCP version has been part of
the IEC 61158 standard (source:
https://de.wikipedia.org/wiki/Modbus
).
ESERA has adopted a Modbus device as bus interface for the 1-Wire Gateway device series and can thus
connect two industrial standards, Modbus and 1-Wire, via 1-Wire Gateway.
During the development of the 1-Wire Gateways, special emphasis was placed on user-friendliness and many
automatic functions. This is additionally supported by our configuration software, Config-Tool 3, which combines
all desirable functions up to the documentation and an installation report.
The ESERA 1-Wire Gateway series makes two industrial bus systems, 1-Wire and Modbus, attractive for a wide
range of applications, even far beyond industry. The range includes IoT as well as Smart Automation and Smart
Home.
