SonarFox UST 20

10 .  Modbus® protocol

A universal communication interface for the communication of the peripheral devices with the 

product. Data communication is via a serial line using the RS-485 standard and the Modbus RTU 

protocol. The list of the respective variables can be found in a separate appendix. The software 

application “Basic SCADA level”, which is freely available on the website www.dinel.cz, can be 

used to set the level meter and record the measured data. The connection to the peripheral device 

can be made via converter URC-485.
