UBALDO GONZALEZ: This video will show you how to create a
numeric data entry and also a display.
Which, the display will show, in numerical value
what the water level is. Whether it is two inches... three inches
four inches... or five and so forth. The
keypad entry or the data entry
will basically allow us to control when the valve
opens or closes. So, if the valve
If the water level is at, say, two inches and I want it to be at
four inches. I can punch in four inches and the valve will
open back up to show to allow water to run in
the tank and this as the tank fills up to four inches
the valve will close. First you go to objects
and this
time we want a numeric entry
We want to do keypad enable
Double-click and I want to go
right here where it says write
tag. Do not do notification handshake or display just do
write tag only. This is my
set point. Which I want to enter my set point
and the highest number I'm going to do is 1050 or
one thousand fifty, which is only four digits.
Click edit tag and everything is already set
I do not want the operator to enter anything higher than
1050. If it does, it will fault the
PLC, so we want to limit the data right here.
Click "ok" and that's already set up.
I can come back over here. Format
background color and also
my text, so click this enter text
and do format again, background color.
And so forth. Next I want to do my
display. So, I'm going to move this over here
and this is going to display the water level in numerical
value. Go to objects
and go to numeric data display and drop it right here
Double-click and change it to
four, because the highest it's ever going to display is 1050.
Read tag, this is going to be
Should be water level
or actually, I'm going to call it a display, because water level represented
the bar graph. This one is going to be the display
right here. Click "ok."
And again, I want to change my background colors for my
text and background color, I want to leave it in black
and there we go. If you notice
how my open and closed changed on my here... I'm going to go back here
and click text
and I'm going to space it out again
or backspace. There we go.
Now, we have a little bit better showing here.
Ok, and that takes care
of this video. The next video will show
you how to do text boxes, which is going to label all of these
objects.
