1 Getting started
Welcome to MON2020—a menu-driven, Windows-based software program designed to
remotely operate and monitor the Rosemount™ XA series of gas chromatographs.
MON2020 operates on an IBM-compatible personal computer (PC) running the
Windows 7® operating system or later.
MON2020 can initiate or control the following gas chromatograph (GC) functions:
• Alarm parameters
• Alarm and event processing
• Analog scale adjustments
• Analyses
• Baseline runs
• Calculation assignments and configurations
• Calibrations
• Component assignments and configurations
• Diagnostics
• Event sequences
• Halt operations
• Stream assignments and sequences
• Valve activations
• Timing adjustments
MON2020 can generate the following reports:
• Analysis (GPA)
• Analysis (ISO)
• Calibration
• Final Calibration
• Validation
• Final Validation
• Hourly Averages
• Monthly Averages
• Daily Averages
• GC Configuration
• Raw Data
• Variable Averages
MON2020 3
Getting started Reference Manual
December 2019 2-3-9000-745
• Weekly Averages
• Dew Temperature Calculation (optional)
MON2020 can access and display the following GC-generated logs:
• Alarm Log
• Event Log
• Parameter List
• Maintenance Log
1.1 MON2000 and MON2020
Users familiar with MON2000 or MON2000 Plus will find a few changes when using
MON2020:
• Login security is at the gas chromatograph level instead of at the software level. This
means that you no longer have to log in after starting MON2020—but you do have to
log in to the gas chromatograph to which you are trying to connect. For more
information, see Connect.
• An Administrator role has been added to the list of user roles. This new role has the
highest level of authority and is the only role that can create or delete all other roles
and users. For more information, see Users.
• Multiple users can connect to the same gas chromatograph simultaneously. By default,
the first user to log in to the GC with supervisor authority will have read/write access; all
other users, including other supervisor-level users, will have read access only. This
configuration can be changed so that all supervisor-level users have read/write access
regardless of who logs in first. For more information, see Managing the system.
•
Users can display multiple windows within MON2020.
• Automatic re-connection. If MON2020 loses its connection with the GC, it
automatically attempts to reconnect.
• Analytical Train Configuration. Users can configure Analytical Trains for the detectors,
valves and discrete outputs enabled by selecting the checkboxes. The number of
detectors, valves and discrete outputs is depenent on the installed hardware of the GC.
• Analysis Clock Configuration Users can configure/save settings of assigned analytical
trains to analysis.
• Users can view multiple instances of certain windows. To aid in data processing or
troubleshooting, MON2020 is capable of displaying more than one instance of certain
data-heavy windows such as the Chromatogram Viewer and the Trend Data window.
• Enhanced Chromatogram Viewer. The following enhancements have been made to the
Chromatogram Viewer:
— Users can view an unlimited number of chromatograms, in any configuration. For
example, a user can view an archived chromatogram and a live chromatogram. For
more information, see The Chromatogram Viewer.
— The Keep Last CGM option. Upon starting a new run, MON2020 can keep the most
recently completed chromatogram on the graph for reference.

— Overview window. When zoomed in to a smaller section of a chromatogram, the
user can open a miniature ‘overview’ window that displays the entire
chromatogram, for reference. For more information, see Additional plot
commands.
— Older chromatograms available. MON2020 has access to archived chromatograms
as old as four or five days. For more information, see Display an archived
chromatogram.
— Full screen mode. For more information, see Options for displaying
chromatograms.
— Protected chromatograms. Chromatograms that you designate as protected will
not be deleted. For more information, see Protected chromatograms.
• The Invert Polarity option. This feature reverses a detector’s effect. For more
information, see Invert the polarity of a valve and Invert the polarity of a discrete input.
• Streamlined variables-picking menu. The method for selecting variables for
calculations and other purposes is contained within one simple, self-contained menu.
For more information, see The context-sensitive variable selector.
• GC Time. The GC Status Bar displays the date and time based on the GC’s physical
location, which may be different than the PC’s location. For more information, see Set
the gas chromatograph’s date and time.
• Daylight Savings Time. You have option of enabling a GC’s Daylight Savings Time
feature. Also, there are two options for setting the start and end times for Daylight
Savings Time on the GC. For more information, see Set Daylight Savings.
• Baseline offsetting (700XA and 1500 XA only). In some situations that involve multiple
detectors, the baseline may be displayed either too high on the graph, in which case
the tops of the peaks are cut off, or too low on the graph, so that the bases of the peaks
are cut off. If this occurs, it is possible to offset the baseline either up or down so that
the entire peak can be displayed on the graph. This offset will be applied to all traces—
live, archived, and saved—that are displayed thereafter. For more information, see
Offset the baseline (700XA and1500XA only).
• Microsoft Excel-based Parameter List. The Parameter List has been expanded to offer
multiple pages of information and is Microsoft® Excel-based to allow for data access
outside of MON2020. The document can be imported to and exported from GCs. For
more information, see The parameter list.
• Optional FOUNDATION Fieldbus variables. If your GC is installed with a FOUNDATION
Fieldbus, you can map up to 64 GC variables to monitor using the AMS Suite. For more
information, see Map a FOUNDATION Fieldbus variable.
• Optional local operator interface (LOI) variables. If your GC is installed with an LOI, you
can configure up to 25 GC parameters to monitor using the LOI’s Display mode. For
more information, see Local Operator Interface variables.
•
Access to GC-related drawings such as flow diagrams, assembly drawings, and
electrical diagrams.
• Validation runs. During a validation run, the GC performs a test analysis to verify that it
is working properly. For more information, see The validation data tables and Validate
the gas chromatograph.

2 Chromatograms
When it comes to viewing and managing chromatograms, MON2020 is flexible and
straightforward. This chapter shows you how to access the Chromatogram Viewer, as well
as how to use the viewer to display, print, and manipulate live, archived (stored on the
GC), or saved (stored on the PC) chromatograms. There is no limit to the number of
archived and saved chromatograms that can be displayed at once. The Chromatogram
Viewer can display all three types of chromatograms together, alone, or in any
combination.
Figure 2-1: The Chromatogram Viewer

B. Time events table
C. Component data table
A chromatogram displays in the Chromatogram window.
Each trace that displays is color-coded; use the Chromatogram drop-down list to select a
specific trace.
Figure 2-2: Chromatogram drop-down list
The list of GC events associated with the production of the chromatogram, along with
each event’s status and time, displays in the Timed Events table to the right of the
chromatogram display window. The Component Data table, to the lower right of the
chromatogram display window, lists the components measured during the analysis.

Chromatograms Reference Manual
December 2019 2-3-9000-745
Note
When displaying a live chromatogram, by default, the timed events and component data
tables are configured to scroll to and highlight the next occurring event in the analysis
cycle. To disable this feature, right-click on one of the tables and uncheck the Auto Scroll
option on the pop-up menu.
2.1 The Chromatogram Viewer
Use the Chromatogram Viewer to display and print live, archived, or saved chromatograms.
There is no limit to the number of archived and saved chromatograms that can be
displayed at once; however, to maximize performance, the number of chromatograms
displayed should be limited to 25 or less. The Chromatogram Viewer can display all three
types of chromatograms together, alone, or in any combination.
The Chromatogram Viewer contains a host of information about both current and past GC
analyses, and it contains just as many ways of editing and manipulating that data.

26 Rosemount Gas Chromatographs
A trace is the graphical representation of the detector output from a
single detector; a chromatogram is the collection of all traces and
associated data that are generated by a gas chromatograph’s
detector or detectors. Each trace displays in a different color.
Reference Manual Chromatograms
2-3-9000-745 December 2019
Retention times
Baselines
Timed event
markers
Peak detection
markers
The retention time, which displays above each component's peak,
is the time that elapses between the start of an analysis and the
sensing of the maximum concentration of that component by the
detector.
The baseline extends from the beginning to the end of a peak. You
can turn the baseline on or off by clicking Baselines.
These markers, which correspond to events from the Timed Events
table, display on the chromatogram as black vertical lines below the
trace-line. There are three types of timed event markers:
• Valve events display as long vertical lines.
• Integration events display as medium vertical lines.
• Spectrum gain events display as short vertical lines.
These markers display on the chromatogram as black vertical lines
above the trace-line. Each peak has two peak detection markers:
one at its beginning and one at its end.
2.1.2 Display a live chromatogram
To view a live chromatogram, do the following:

Final Calibration
chromatograms
As long as there is space, MON2020 stores all final calibration
chromatograms; once space runs out, MON2020 deletes the
oldest non-protected final calibration chromatogram for each new
final calibration chromatogram that is created. If multiple final
calibration chromatograms are created on the same day, the last
chromatogram created is archived, unless MON2020 has been
configured to archive all final calibration chromatograms.
Note
See Managing the system to learn how to configure MON2020’s
archiving behavior.
Final Validation
chromatograms
These chromatograms are treated in the same manner as final
