Product features
Standalone controller
The 1-Wire Gateway 11 Modbus is designed to control 1-Wire Networks. You no longer have to worry about
1-Wire commands or algorithms to analyze sensor data. 1-Wire Gateway 11 Modbus scans 1-Wire Networks
by itself in order to identify new sensors or actuator devices. All data found were automatically provided in a
ready to use Modbus protocol format.
Formatted Data Output
1-Wire Gateway 11 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 11 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 11 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
our webpage. Communication to Modbus TCP is parallel with no switching.
System time / real time clock
No real time clock available in your system? No problem at all. 1-Wire Gateway 11 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 11 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.
Operation
“How-To”-Videos for setup and operation can be found on our website
