Description
Modbus master to SDI-12 Slave converter TBS09S connects one or more SDI-12 sensors
The Modbus master to SDI-12 Slave converter TBS09S from Tekbox is a converter for connecting one or more SDI-12 sensors to a Modbus device such as a data logger or telemetry device. The converter is inserted between the data logger or RTU with Modbus interface and sensor(s) with SDI-12 interface. The term Modbus Master to SDI-12 Slave is ambiguous. Looking purely at the converter, the device has a Modbus slave interface on one side and an SDI-12 master output on the other. However, when looking at the application, the device is a converter between a Modbus master (data logger, RTU, etc.) and an SDI-12 slave (sensor with SDI-12 interface).
The diagrams seen in the product gallery describe a typical use of the TBS09S module. A Modbus telemetry device is bridged with an SDI-12 sensor. It is seen how the internal TBS09S Modbus / SDI-12 layers interact with them.
