Screen 2 consists of:
one Text object with the screen title CONVEYOR CONTROLS
.
one “Return To Previous Screen” Button labeled MAIN SCREEN
.
five Momentary Push Buttons—Normally Open with indicator state text
inside the buttons and “outer text” above the buttons
five Momentary Push Buttons—Normally Closed with indicator state
text inside the buttons
Each push button has two possible states to which different text and
attributes will be assigned.
Each of the ten push buttons on this screen has a unique PLC input bit
address. You will program your PLC controller to turn on a conveyor when
its respective Momentary Push Button (Normally Open) is pressed, and to
turn it off again when its respective Momentary Push Button (Normally
Closed) is pressed.
Each of the ten buttons also has a unique PLC output bit address. These are
referred to as the “Indicator Control Bits”. Your PLC program should
include the logic to set the appropriate Indicator Control Bits to show that
the conveyor is on or off.
