One of the components of BatchView
is the PI ProcessBook add-in.
You will know if you have the PI ProcessBook add-in
loaded if you have this symbol. It looks like a
tank with a black arrow moving through it. That's called the
Batch Group Symbol. You will also see that
in your displays in the Draw Menu. If you see Batch
Group, you will know you have the BatchView
add-in installed on your machine.
Now the BatchView add-in contains four components. It's
got a Batch Search Component, a Results Table,
A Gantt Chart, and Batch Trends. And you
can have one or more Trends in your Group.
And the way the Group, the Batch Group works, is that you are
presented with a Search Component in
ProcessBook. You display that information
in ProcessBook. You get a Results Table. And the
Results Table can feed both the Batch Gantt Charts
which also can feed the Batch Trends. So, there's a lot
of different ways that this becomes inter-
active once you place it into ProcessBook and
we will show you how to do that.
Some of the common things people use BatchView for is
to do Batch-type comparisons. This is mostly using
the Gantt Chart functionality. People will
do Process Value comparisons. This is
primarily accomplished using the Trending Tools.
And Cycle-Time Analysis. People want to see
and analyze what their down-times are for particular
pieces of equipment. The Plot Time
Settings deserve some attention because they can be a little confusing.
They are found on the Settings
Panel. If you go into Build Mode and double-click
your Batch Group, you will get
the Batch Definition Dialog Box,
and click Settings. And, you have three
options in setting your Plot Time. And this is
essentially your X Axis for the Batch Group.
Relative-Start and End Time -- that's the
default methodology. The Start is
your Batch Time Start, and the End is your Batch End.
And if you wanted to change that at all
by using -- setting
it differently, like you wanted to start ten minutes into the Batch,
you would simply put a. a
+10m there, and that would start
the Batch ten minutes into the Batch.
And that's actually shown on this slide
where we have a ten-minute offset time in the Batch.
You can see that the Times along the bottom of my Trend
here start essentially at ten minutes.
We do not see the beginning of the Batch, whereas in the top
Trend we have the
entire Trend shown. We start at the zero point
of the Batch. The last
one, the ending one, is sort of a combination of the two, where it's a
ten-minute offset, but it's Time into Plots. That means
we actually start the Plot Time
at ten minutes, and that's the zero point. So, the difference
between Time into Batch and Time into Plot
is essentially where it's showing you the zero point. If you
use Time into Batch, it maintains the timing along
the bottom of the Batches, and starts ten minutes
in. But, if you use 10-minute offset Time into Plot,
it actually sets that 10 minutes into the Batch
as the zero-time of the Plot, and uses that
as the access. There's a couple other
attributes here. You can use a Relative Time
if you want to always have your Times
aligned to a certain component
of your Trend. Let's say, for example,
I wanted all of my, all of my Elements,
my Gantt and my Trends, to start with this
Prehydrolysis Phase. I can align all
of the things to the Prehydrolysis Phase
and that way all of my Gantts
and Trends will automatically align
to that particular Phase. So, you can set that if
you'd like. Or, you can just say Absolute.
And Absolute is simply going to give you
a Trend that's going to look like --
it's going to look like a ProcessBook Trend, where
things are not overlaid but it's actually shown as
Actual Time, and we will see an example of where this is used
a bit latter. Batch Trend Configuration is
performed much like the Trend is in
ProcessBook. If we go into ProcessBook, and we look
in our Batch Definition Window, and we select
Layout -- for each of our Trends, we
have a Configure Button. And I have one Trend here, and I will
bring up the Configuration, and you will see the available
aliases and tags aliases in the Trend are displayed the, the same
as the initial configuration.
But toward the bottom we have a Scaling Setting. And the Scaling Setting
is almost identical
to the ProcessBook Setting with
one small distinction. We have this By Tag-
Alias. And so,
if we select Single Scale, we get one
trace, one Scale for all of our traces.
This is identical to the way ProcessBook works.
There's also a Multiple Scale Option. And this, again, is
identical to the way ProcessBook works, where,
if you have Multiple Scales
with your +Tag Aliases checked, you get one Scale
for each Alias and one Scale for each Tag. So,
for each item that you are showing on the right,
you get one Scale. And that's pretty much the same as
ProcessBook does. However, if you do not check
+Tag Alias in the Configuration,
what you will get is you will get a trace for
every single -- you will get a Scale for every single
trace on the screen. And that is very different
than Processbook. And ProcessBook's not
showing you the same trace for multiple tags.
There's also the Trend Format Configuration
where you can control
pretty much everything you control in the ProcessBook
Standard Trend Object. You have Line, Weights,
and Styles for each pen. You have
all the Elements here: the Text, the
Access -- Axes, the Grids. You can control the Line Weight and Color
for that. You can display whether -- choose to
display to show the Title, the Grids, the Vertical Scales,
Inside or Outside Access. And you can show
a Legend if you want by showing different items
at the bottom of your Batch Trend
Element. So, you have most of the same Options that you have
under Format that you have in ProcessBook. They are just laid
out slightly differently.
