Answer
# 5
There is no difference between HMI and MMI.
MMI stands for Man Machine interface.
HMI stands for Human Machine Interface.
Then there will rise a question why there are two terms.
In the ewarlier days only men used to work in any control
room. But now a days womwn are also working in all Controll
rooms.Hence the word HMI has been ome in usage.Just to
avoid any doubt that in control both men and women can work.

Answer no 5 seems to be correct with answer no 3. Intially
the machine interfaces are having limited capabilities and
then enhanced to higher levels. So answwer no 3 may be
taken as correct and while renaming while tech advancing
Answer no 5 must have been considered.

There was an another term calleed GUS: Global User Staion
honeywell systems.
But HMI stands dominating. MMI (favour towards men), GUs
(not specific for machine interface)

This is what I belive.
