As the name implies, like a supervisor who supervise his
subordinates functions and control over them.
Particularly in SCADA(supervisory control and data
aquisition)from HMI ie.. simply from monitor screen u can
supervise the various functions in the plant and also
control them by changing set points etc.. .Usualy SCADA
comprises of PLCS(functions as supervisor in auto), a
communication mode to receive data to and fro and a manual
interface ie.. for example graphics to communicate with
the PLC
