Modbus monitor system

By using a Modbus Human Interface Monitor and A/D module , a simple tank level monitor system could be built. Through alter the A/D configuration parameters , such as tank capacity , tank height , sensor convertion , the data are kept into the internal flash memory for permanent storage.

 

To trouble shoot existing modbus system onboard , we start from the tank level transducer , the A/D module , internal convertion data and the display interpret setup as well.
