Introduction
Plant View is a tool in Aspen HYSYS that enables users the ability to view plant data side by side with model results in
the simulation environment. View real-time, time-averaged, or historical data side-by-side with predicted stream data.
Plant View gives process engineers the ability to facilitate better, smarter operational decisions by promoting the use of
simulation results in operations. This Jump Start Guide is a brief tutorial to help users get started with Plant View in less
time.
This is not meant to be used as a stand-alone reference document. AspenTech recommends that a range of other
resources be referenced to give the new user a comprehensive view of how to use Plant View in Aspen HYSYS. These
may include:
• AspenTech support website (support.aspentech.com)
• AspenTech courseware available in on-line and in-person versions
• AspenTech business consultants
• Additional Jump Start Guides—available on a variety of related topics
This document covers mapping specific plant data tags against selected model stream variables in Aspen HYSYS. It
assumes that the user has Aspen HYSYS V8.0, a data historian such as IP.21, IP.21 Process Browser, and Internet Explorer
9 or higher. Note: Internet Explorer 8 is also compatible; however, the Google Chrome Frame must also be installed.
Activating Plant View
Plant View can be activated by pressing the Plant View button in the show group of the View Tab.
Figure 1: The Plant View button in the show group of the View ribbon
Clicking the Plant View button will create a new Plant View contextual ribbon and open a Plant View Flowsheet. The Plant
View Flowsheet will be similar to the Main Flowsheet; however, it will contain stream animations, a table of mappings,
and a reference key.
2
Figure 2: The Plant View Flowsheet
Interpreting the Flowsheet
Stream Color & Animations
The Plant View flowsheet is unique in that it uses colors and animations to represent stream properties. The color of the
stream indicates the phase of the stream and the animation represents the relative flow rate. On the right side of the flow
sheet, there is a Stream Animation Legend.
Figure 3: The Stream Animation Legend
Customizable Stream Tables
Stream tables can be activated by right clicking on the stream label and selecting Stream Table. Quickly and easily
manage which stream variables are displayed in the stream table with the Stream Results group in the Plant View tab or
by right clicking anywhere on the flowsheet, highlighting views with the cursor, and then selecting “Filter Data Views”.
Selecting Filter Data Views will prompt the Stream Data View Filter form.
3
Figure 4: Stream Data View Filter Form
Composition Pie Charts
Composition pie charts provide a quick visual representation of the predicted stream composition. Composition pie charts
can be accessed via the Stream Data View Filter form (accessing this form is outlined in the Stream Tables section). In
this dialogue box, users can specify the location of the pie chart and also either a molar or mass basis. Each colored piece
of the pie chart represents the presence of a different component. The key for the composition colors is located above the
stream animation legend on the right side of the flowsheet.
Figure 5: Stream table with the corresponding composition pie chart
Subflowsheets
The Plant View flowsheet includes a hierarchy browser which allows for quick and easy transitions between the flowsheet
and subsequent subflowsheets. This operation can be completed using the Hierarchy Browser or by simply double
clicking on the subflowsheet unit operation.

Stream Tables
To view a stream table, right click on the stream label of choice and select the Stream Table option. The variables that
appear in the stream table can be customized via one of two ways. The first option is to right click anywhere on the flow
sheet and then highlight Views, then select Filter Data Views. The second option is to select or unselect variables in the
Stream Results group on the Plant View Ribbon.
Figure 8: Customize Stream Tables via the Stream Results group on the Plant View ribbon
Figure 9: Filter Data Views
Configuring the Server
In order to view Plant Data in the Plant View environment, the plant data source must be specified. Prior to mapping the
data, IP.21 Process Browser must be installed on a separate server where it will point to a plant data server. Once this
step is complete, specify the Plant Data Source by clicking on the Source button in the Plant Data group on the Plant View
ribbon.
Figure 10: The Source button in the Plant Data group of the Plant View tab
This will open the Plant Data Source form where the web21 URL of the data server should be entered. Once the URL is
specified, the data source name can also be specified. In this example, the data server is “plantdata” and the data source
is also named PLANTDATA.
6
Figure 11: Aspen Search: Plant Data Source form
Note: The general form of the plant data source URL is:
http://<servername>/web21/processdata/atprocessdatarest.dll
This is a web server that can be connected to plant data from a different server.
Viewing Data
Mapping Plant Data to Stream Variables
In order to view plant data side-by-side with simulation results, it is necessary to map plant data tags to the stream
variables. Right click on the stream of interest, and select “Tag Mapping”. This will open the “Steam Variable to Plant Tag
Mapping” form.
Figure 12: Aspen Search: Stream Variable to Plant Tag Mapping form
7
The dialogue box is powered by Aspen Search which enables users to search for tags based on their name, unit of
measure, tag ID, type, or description. Aspen Search also automatically filters by variable type. For example, when
searching for a temperature it will automatically filter to show only data sources measured with units of temperature.
Figure 13: Search results for the temperature Simulation Variable
Once the tags are mapped, select OK and return to the flowsheet.
The next step is to activate plant data views in the Plant View Flowsheet by checking the Stream Data Viewer, Flowsheet
Data Viewer, and/or Plant Data boxes in the Display Options group on the Plant View Tab.
Figure 14: Plant Data box on the Display Options group of the Plant View tab
Data View Options
Plant Data
The Plant Data Viewer attaches a plant data column to stream tables, enabling a side-by-side comparison of plant data
and simulation results.

Flowsheet Data Viewer
The Flowsheet Data Viewer provides a view of every mapped variable in the flowsheet in one place. Flowsheet Data
Viewer allows for easy navigation of mapped variables in the Plant View environment.

17: Flowsheet Data Viewer Toggle Button
Figure 18: Flowsheet Data Viewer
Stream Data Viewer
The Stream Data Viewer option enables users to either activate or deactivate all of their stream tables.
Figure 19: Stream Data Viewer box
Time Filters
Once the Plant Data Tags are mapped, the data can be manipulated by several different time filters such as real time,
time averaged, or historical averaged. Real time data is the actual data being measured once every ten seconds. Historical
averaged data is viewed over a specified range of time, such as the past three months. Time averaged data is viewed over
a specified time period, such as the past thirty minutes. All three data views are accessible via the Average Range button
in the Plant Data group of the Plant View Ribbon.

Figure 21: Plant Data Averaging Range Settings form
Data Plots
Plant View enables users to view previews of plant trends in plot form. To view, simply hover over the desired variable in
the Flowsheet Data Viewer or Plant Data Viewer attached to the stream table.
Figure 22: IP.21 trend plot
High Performance Trends
Plant View V8.2 provides users access to IP.21 Process Browser High Performance Trends from within the common shell
of Aspen Plus. High Performance Trends allow you to access more historical data for each tag through IP.21 Process
Browser Web Plots. You can also view multiple tags concurrently. This allows for more detailed views of the plant data, a
larger range of data, and the ability to see the behavior of multiple tags with respect to other tags.
To plot multiple tags, you must first activate the toggle buttons next to the tags you want to plot in the Flowsheet Data
Viewer.
10
Figure 23: Selecting multiple tags
Clicking the “Plant Trends” button in the Plant View Ribbon (Figure 24) will open an IP.21 Process Browser Web Plots in
a new tab. You may be prompted for authentication from the plant data server if there are additional security restrictions
set by your IT Administrator. Use the login information for the Plant Data Server, not the client machine.
Figure 24: Plant Trends Button in Ribbon
Figure 25: Plant Trends Browser Tab
The plot range is highlighted with sliders that adjust the range of the data based on the period of time selected. Clicking
and dragging the plot in either direction allows you to scroll backwards and forwards in time to see historical plant trends.
To export a summary of tag information to Excel, click on “Tag Summary”
Figure 26: Tag Summary Button in Plant Trends Browser Window
11
The exported summary includes the tags included on the plot, number of points in the range, the minimum and maximum
values for each tag, the average value of the range, and the standard deviation. This data is time stamped and references
the tag names and the plant data server where the tags originated. When the plots are supported with this information,
the user can visually judge how noisy the plant data is in this time period.
Figure 27: Tag Summary Excel Worksheet
To view trends for a single plant data tag, simply map the tag to the desired stream and then select the stream variable of
interest by left clicking on the tag value in the Stream Table.
Figure 28: Selecting Tags from Stream Table
This will open up a Plant Trends Browser Window for that single tag. All other functionalities within the browser window
will remain the same.
Figure 29: Plant Trends Browser Window for a single plant data tag
12
Importing & Exporting Data Maps to Excel
Plant View enables users to compare multiple sets of plant data tags to one model by saving the data maps. Plant Data
maps show up on the Flowsheet Data Viewer table.
Figure 30: IP.21 Flowsheet Data Viewer table
There are two different ways to export maps from Excel. The first type is time stamped and does not include the plant
data tags. The second type includes plant data tags. Exporting without the tags is the best option for creating data fits in
Excel.
To export the maps, click on the Excel icon near the upper right hand corner of the Flowsheet Data Viewer table.
Figure 31: Excel export button
The exported map will look like this:
Figure 32: Time stamped file exported into Excel
This can be saved and imported back into Plant View. This feature is convenient because it allows users to capture
behaviors of the plant data at specific times.
To export a map with tags, click on the Export Map to Excel Button in the plant data group on the Plant View tab.
13
Figure 33: Export Map button in the Plant Data group of the Plant View ribbon
Figure 34: Excel file with Plant Data Maps
As shown in Figure 27, this map points to the data server; therefore, when the file is imported into Plant View, the data
tags are live. By saving data maps and tags in this fashion, multiple tags can be mapped to the same models and vice
versa which allows for case comparison and troubleshooting.
Use Case Scenarios
Plant View enables users the ability to view plant data by simulation results—a technological first in the process modeling
industry. This technological breakthrough can be applied to several different use case scenarios in plant operations.
Plant View promotes informed decision making by reducing the hassle and time required to compare simulation results
with actual plant data. By using simulation results in conjunction with live plant data, process engineers can employ
what-if scenarios prior to altering operating conditions in the plant, resulting in better, more informed decisions.
Plant View can also aide in troubleshooting previous plant operational problems. View plant data corresponding to the
incident, and then run the model until the simulation results match the plant data. Once the simulation converges to
match the plant data, process engineers can find the origin of the problem and hopefully avoid such problems in the
future.
