1 Getting started
Welcome to MON2020—a menu-driven, Windows-based software program designed to
remotely operate and monitor the Daniel
®
Danalyzer
™
XA series and the Rosemount
®
Analytical XA series of gas chromatographs.
MON2020 operates on an IBM-compatible personal computer (PC) running the Windows
XP 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:
• 24-Hour Averages
• Analysis (GPA)
• Analysis (ISO)
• Calibration
• Final Calibration
• Validation
• Final Validation
• Hourly Averages
• Monthly Averages
• GC Configuration
• Raw Data
• Variable Averages
• Weekly Averages
Getting started

• 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 Section 1.2.12.
• 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.
For more information, see Section 7.3.
• 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
Section 4.1.
• Users can display multiple windows within MON2020.
• Automatic re-connection. If MON2020 loses its connection with the GC, it
automatically attempts to reconnect.
• 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 Section 2.1.
- 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 Section 2.3.2.

- Older chromatograms available. MON2020 has access to archived
chromatograms as old as four or five days. For more information, see
Section 2.1.3.
- Full screen mode. For more information, see Section 2.2.
- Protected chromatograms. Chromatograms that you designate as “protected”
will not be deleted. For more information, see Section 2.1.4.
• The “Invert Polarity “option. This feature reverses a device’s effect. For more
information, see Section 3.2.4 and Section 3.5.4.
• 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 Section 1.11.
• 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
Section 2.6.
• 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 Section 2.6.1.
• Baseline offsetting. In some situations that involve TCD 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 Section 2.5.7.
• Microsoft Excel-based Parameter List. The Parameter List has been expanded to offer
seven pages of information, and is Microsoft
®
Excel-based to allow for access
outside of MON2020. The document can be imported to and exported from GCs.
For more information, see Section 5.3.
• 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 Section 4.14.
• 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 Section 4.13.
• Access to GC-related drawings such as flow diagrams, assembly drawings, and
electrical diagrams.
