scada is the software but hmi is software hardwear both ,it is the sub set of scada.scada having the capability to store lots of data but hmi having limited option.

There are different communication protocols between PLC and the SCADA. Popular SCADA being PC based, most used communication protocol is ethernet/IP. The PLC tags are used to build the objects in SCADA so that Actions or states or status or parameters of PLC are displayed on SCADA.
Most large machines have a big red button on the human-machine interface panel (HMI panel). When I push the big red button, everything on the machine stops, including the programmable logic controllers (PLC).

The difference between performance of 89c51 and 89s51 is that the 89c51 has a standard 51 core. The 89c51 program cannot be directly ported to 51 compared to the 89s51.

SCADA stands for Supervisory Control And Data Acquisition. It generally refers to an industrial control system: a computer system monitoring and controlling a process,A Human-Machine Interface or HMI is the apparatus which presents process data to a human operator, and through this, the human operator, monitors and controls the process.
HMI stands for Human Machine Interface. MMI is an older term meaning Man Machine Interface.

MIMIC diagram is the representation of a circuit. Mimic is graphical representation on HMI or SCADA or even on a panel with the help of LED,S and circuit flow diagram. One can represent flow in the plant status of motors, valves damper etc also

scada is already abreviated! mabye it is scda??
HMI is "human machine interface" for short. It's the interaction between humans and machines. The goal of this interaction is effective operation and control of the machine on the user's end. The feed back from machines aids the operator in making operational decisions or improvement. For example, if you want to do detailed control to a machine. For main objects, you need a hmi and plc. You can do the operation on hmi's touch panel, then hmi send the command to plc, and plc deal with and process the command. Without hmi, you can't reach to the detailed controls, and only simple can be done.
SCADA will perform supervisory action over Distributed control system to make sure that every thing is working fine.
PROMOTIC SCADA system was created in 1991.
SCADA is an acronym for Supervisory Control and Data Acquisition. SCADA usually refers to an industrial computer system that monitors and controls a process.
