Answer / nikita
SCADA stands for supervisory control and data acquisition.
It generally refers to industrial control systems: computer
systems that monitor and control industrial, infrastructure,
or facility-based processes
A SCADA System usually consists of the following subsystems:
hmi
plc
rtu
communication interface
HMI is the apparatus which presents process data to a human
operator, and through this, the human operator monitors and
controls the process.
so basically we can say hmi is a part of scada but scada is
not the subsystem of hmi

Answer / ashish gupta
HMI(Human Machine Interface) is a system that shows the
plant parameters to human operator, operator only can see
the parameters and cannot change them.
Where as SCADA is a system which shows the parameters and
also logs the data and alarms and through this data also can
be changed.
