Formatted data output
1-Wire Gateway 20 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
The 1-Wire interface of the 1-Wire Gateway 20 Modbus is specially designed to securely support all sizes
of 1-Wire networks. 1-Wire sensor devices can be operated in parasitic or normal mode at the same time.
The latest available most powerful 1-Wire interface for a maximum level of data security has been used.
This includes complex network structures as well.
1-Wire Gateway 20 Modbus configuration
Free configuration software (Config-Tool 3) is provided. When using Config-Tool 3, the latest
documentation is available at any time hence it automatically updates via internet. This software is
available for
on our webpage. Communication to Modbus TCP is parallel with no switching.
System time / real time clock
No real time clock with battery buffering available in your system? No problem at all. Our 1-Wire Gateway
20 Modbus is providing time and date as real time clock including an integrated backup battery. Data
plausibility check is possible at any time.
Power supply
Input voltage for 1-Wire Gateway 20 Modbus is 9
– 30 VDC. Therefore it can be used for 12 V as well as
24 VDC (industrial applications). Appropriate hat-rail mounted power supplies or power plugs can be
found in our webshop.

Auto-E-Connect® Support
The ESERA
Auto-E-Connect®
1-Wire Plug and Play system will be used for the
1-Wire Bus supported. This enables fully automatic configurations of 1-Wire sensors
and actuators on the 1-Wire bus. It is optimized for industrial applications and
enables significant added value beyond the sensor and chip data.
The Auto-E-Connect function automatically recognizes ESERA chips, sensors and actuators, starts suitable
libraries and outputs fully formatted data.
The Auto-E-Connect functionality will be available from mid-2020 via 1-Wire Controllers, 1-Wire Gateways and
1-Wire ECO from ESERA available.
Further information on ESERA Auto-E-Connect can be found on the ESERA website, ESERA Config-Tool 3,
or in the download area for this article in the ESERA Webshop.
