7. Remote HMI application
HOST HMI
Client HMI_1 Client HMI_2 Client HMI_3
USER DATAGRAM PROTOCOL (UDP server/client communication)
 Now operator can control drive remotely
 Drive and HMI should be in same network
 Uses UDP comm. Protocol (Mostly used in real time comm. systems)
at port 11000
Advantages:
 No need to install driver on every computer
 Every computer can work as operator station

15. Electric Motor
 A universal motor is a single-phase series motor.
 Universal motor is able to run on either ac or dc .
 The field windings of a series motors are connected in series with the armature
windings.

16. Construction of a universal motor is similar to the construction of a DC series motor.
The whole magnetic path (armature, stator field circuit etc) is laminated.
The flow of current is in one direction in all the conductors on one side of the
armature, and in the opposite direction in all the conductors on the opposite side
of the armature.

20. We know that In the coming years new technologies are
created and everything will be supervisory control.
Automation system provide excellent services in installation and
commissioning for various industrial manufacturing, production,
power generation, fabrication, chemical, Petrochemical, and
refining processes and day by day it is getting wider.
The increasing capacity of microcontrollers continues to offer new
opportunities for product differentiation in real-time control
systems.
