DESIGN PROBLEM
PROGRAM DESIGNING USING PLC, ANALOG CONTROLS, HMI AND VFD
APPLICATIONS
For this design, the program must have 4 screens. In the first screen, a welcome and the
names of the groups members must be in there, and also the names must blink or flash
continuously. A next button must be located in the lower right of the program which switches
to the next screen which is screen no.2. for the second screen a numerical keypad must appear,
in the keypad, there will be numbers from 0-9, a clear and an enter button. The user must input
a password which could equal the operator or the engineer. In our program the operator is 123
and 200 for the operator. When it equals the operator it should switch to the next screen but a
config button located in the third screen is disabled. When it equals the engineer, it switches to
the next screen but this time he can access the config button which points to the 4th screen. The
3rd screen contains the buttons which controls the motor. It consists of a start, stop,
reverse/forward, remote/local , config , button and again a numeric keypad. The numeric
keypad controls the frequency of the motor. There are three indicator lamp which designates
whether it is in local or in remote, running or in stop state. Pressing the “local” button means it
will go to local mode which means the control will be on the digital operator. The screen will
change its color/background which designates that it is disabled and will unable to press.
Pressing config will switch to the 4th screen, in this screen there is again a numeric keypad
which changes the value of the engineer and operator password. An exit button must be
pressed in order to exit the program to the first screen again.
