## An RTU can have 0-5 input or 4-20mA input or RS232 input or RS485 (MODBUS Protocol) input to fetch data from the field instrument and to send it to a remote server for further processing. The raw data received this way can be processed by applying formulae and functions to get the actual displayable value. This value can then be displayed on a web interface or SCADA for live monitoring and analysis. This value can also be saved in data base for future use and report generation etc.,.
