I want to show you how you can use PI
Vision to build a customized display to monitor your process in just a
few minutes with only a web browser. First I'll
go to my machine
at forward slash PI Vision and go straight to the
homepage. Now let's imagine this scenario,
I'm an engineer and I get a call from my manager
and she says I'm getting reports that the pumps at our Philadelphia
plant are acting up. It sounds like the bearing temperature
is going out of spec. Can you take a quick look and
present at our group meeting in 15 minutes? Let me
show you how I can use PI Vision to prepare for my
meeting. The first thing I'll do is click the new display button
here. The basic instructions are listed
inside the display. If I happen to know the name
of my PI Point for the pump, I can enter it inside of the
search box. But let's pretend that I don't.
I'm able to navigate to my asset if I have my asset
framework structure setup. My manager mentioned that the problem is occurring
at the Philadelphia plant, so let's search for Philadelphia.
And drill down to my pump.
I'll select it and now I can see all of my
attributes here. Since it's the bearing
temperature that's a problem, I'll
choose that. And then using this symbol gallery, I'm going to
choose a symbol that will help me visualize
it. I have a choice of a trend, a value, a
table, three different gauges
as well as an asset comparison table. By
default, trend is selected, so all I have to do is
drag bearing temperature inside the display.
I'll make it a
little bigger. And I'll
also add some other process parameters
as well holding the control
key.
To help my
team get a clear picture of what this trend is
about, let's add a pump image to customize this
display. I can grab a stock graphic in the graphic
library here but I happen to have my own
image. So I'll choose the image icon,
create a placement area.
And browse
to my image.
Since we know
that the bearing temperature is a problem,
I want to see it as a vertical gauge to get more
visual context. I'll find it
again. Select
it. Choose a vertical
gauge. And add it to the display.
I'll do the same for the discharge
flow rate. And I'll do the same for the discharge flow rate.
But what if I want to change my symbol?
All I have to do is right click it and
switch it. And I'm going to switch it to
radial gauge.
Also add a label, I'll hit the text icon
and I'll call my
display Pump
Conditions. Change the color
to yellow, make it
bigger and place it right
here. I can change
my duration from 8 hours to 1
hour and go back in time to see how
my parameters have been
behaving. It has only been a few
minutes and I already have the information I need for
my meeting. I can figure out when was the last spike in the bearing
temperature and what was going on with the flow rate and other parameters
at the time. Now I want to provide
more context. It's not just time series data that I'm
interested in. If I have asset framework, I
can view calculated data and maintenance information. So let me
add that as well.
I'll choose that, select
table and add the table to my
display. I'll also
add the installation date and the
maintenance date.
I'll clean up the table by configuring it,
right click and
remove the columns that I don't
need.
I'll make this column a little bigger by
double clicking the border
and
adjust this. And now I want
to add a name of my asset to visualize it as a
value. I'll find it in the attributes
pane
and choose value and drag it
inside. And I'll do the same
for the status of the pump to know if it's
on.
I'll format the values by right
clicking them and under
visibility I'll remove the label, the units and
the timestamp and change the color of the
value to orange.
Now do the
same
for this value. I'll simplify the label,
remove the units and timestamp and change the
text color to orange as well.
Now we just customize
the values and we can do the same things for other
symbols just by right clicking them.
I'm going to change the label to
bearing.
And change this one as
well.
Great, now let me save my
display.
You just saw that we exited design mode because the
orange frame around the display has disappeared.
I can bring it back by going back to the design mode
icon. So if I click it, we're back in design
mode. When I exit design mode, there is a lot I
can do. I can't move the symbols
but I can do a deeper dive inside my trend. For
instance, I can zoom into an area of interest
by dragging it. I can
also move back in time by selecting the lower
section of my trend to see how my process
variables have been behaving.
I also
can add
trend cursors by clicking anywhere inside the trend.
I'm getting a specific value for each trace at
every moment. To remove the
cursor, all I have to do is hit control z to undo.
I'll go back to 8
hours
return to the present moment to see
real time data. Now if I want to, I can
also see the process parameters of my other
assets by using the asset switch here.
So I'll take a look at pump 2 and
3.
Great. This display does exactly what I
need. This is an awesome dashboard that I created in
just a few minutes inside a browser. And now I'm all
set for the group meeting with time to spare to grab a coffee.
