Getting started

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

Getting started

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.

Getting started

- 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.

• Validation runs. During a validation run, the GC performs a test analysis to verify that

it is working properly. For more information, see Section 4.4 and Section 6.4.

2 Chromatograph

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, or saved 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.

The Chromatogram ViewerFigure 2-1:

Chromatograph

A. Chromatogram window B. Time events table C. Component data table

A chromatogram displays in the chromatogram window. If the chromatogram contains one trace, the Det1 checkbox is automatically checked; if the chromatogram contains two traces, the Det1 and Det2 checkboxes are automatically checked. To remove a trace, uncheck its detector checkbox.

Each trace that displays is color-coded; use the Chromatogram pull-down menu to select a specific trace.

Chromatograph

Chromatogram pull-down menuFigure 2-2:

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. These tables are updated in real-time, just as the chromatogram is.

Note

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.

2.1.1 Data displayed in the chromatogram window

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.

Chromatograph

• Spectrum gain events display as short vertical lines.

Peak detection markers

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:

1. Connect to the GC.

2. Select Chromatogram Viewer... from the Chromatograph menu.

Note

Another way to display the Chromatogram Viewer is to click , which is located on the Toolbar.

3. From the Chromatogram Viewer window, select the View current CGM check box.

2.1.3 Display an archived chromatogram

Archived chromatograms are stored on the GC, so you must be logged in to access them.

Archived chromatograms are sorted and displayed on four tabbed panes:

Chromatograms This view displays all chromatogram types sorted by time so that

the newest file is always listed first. This view can be further configured to display only the files from the last five runs for each stream, or to display all the files that are stored on the GC.

Protected chromatograms

Final Calibration chromatograms

Protected chromatograms are never deleted from the GC. To protect a chromatogram, see Section 2.1.4.

Note

Protected chromatogram files have a “lock” icon ( ) displayed beside them.

As long as there is space, MON2020 will store all final calibration chromatograms; once space runs out, MON2020 will delete 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 Section 4.1 to learn how to configure MON2020’s archiving behavior.

Final Validation chromatograms

These chromatograms are treated in the same manner as final calibration chromatogram files.

To view one or more archived chromatograms, do the following:

1. Click GC Archive.

The Select archive file(s) window appears. The files can be sorted by date, file name, analysis type, time, or stream number by clicking the appropriate column header. By default, they are sorted by date, with the newest file listed first.

This window automatically displays whenever you zoom in on the original chromatogram.

Resizes and offsets two or more traces so that they can both be fully displayed on the graph. To offset a trace means to raise its Y-axis relative to the Y-axis of the previous trace so that one trace is not drawn over the other but instead one trace is drawn above the other.

Indicates the amount of offset between two or more traces. To offset a trace means to raise its Y-axis relative to the Y-axis of the previous trace so that one trace is not drawn over the other but instead one trace is drawn above the other.

If two detectors are in use, each set of traces can be offset independently--that is, the traces for one detector can be offset relative to each other, but independent of the traces from the second detector.

2.4 Change how a chromatogram displays

The Chromatogram barFigure 2-7:

Chromatograph

The Chromatogram bar contains a row of buttons that allows you to manipulate a single chromatogram. Below the row of buttons is the Chromatogram bar's pull-down menu, which contains a list of all of the currently displayed chromatograms/traces. Before you can work with a chromatogram you must first select it from the pull-down menu.

2.4.1 Edit a chromatogram

You can use the Edit function to change the X and Y offset values for a trace, as well as its color. These changes may be necessary to make the trace more distinguishable from those that surround it, or to align a trace with a different trace for comparison.

3.1.7 Set PWM Output

Note

Pulse-Width Modulation (PWM) is a technique for providing intermediate amounts of electrical power between fully on and fully off.

A heater needs voltage to operate. The amount of voltage that is delivered to a heater can be controlled manually when the heater is set to Fixed On mode. Setting a heater to Fixed On mode can be useful when troubleshooting heater issues.

Hardware

CAUTION!

Fixed On mode is not recommended for general GC operations. Switching a heater to Fixed On mode removes its ability to maintain a constant temperature because the power delivered to the heater will not fluctuate based on the temperature setpoint, but will instead remain at the level set by the user.

To set a heater’s PWM Output, do the following:

1. Select Heaters… from the Hardware menu.

The Heaters window displays.

2. For each heater that you want to set, select Fixed On from the appropriate row under the Switch column.

3. For each heater that you want to set, double-click on the appropriate row under the Fixed PWM Output column, and enter the desired percentage of output. You can enter a decimal value between 0 and 100.

Application

Maintenance Mode Switches the GC to maintenance mode and triggers an alarm that

the GC is down for maintenance.

Ideal RF Order/ Limit Check

Applies to the 370XA only. If enabled the GC will verify the following during a calibration:

• The order of magnitude of the response factors for all the

components should be in a particular order. The GC will verify that the response factors follow this pattern.

• The response factor ratio for each component with respect

to a reference component should be within a pre-defined range. The GC will verify that the ratio is within acceptable limits.

Application

Max Warmstart Delay

Applies to the 370XA only. This is the maximum time, after a GC recovers from a power failure during normal operation, that the GC will wait for the heaters and electronic pressure controller to reach their respective set points and stabilize before triggering the Warmstart Failure alarm.

EV Check Applies to the 370XA only. If enabled, the GC analyzes the

calibration gas as an unknown stream and computes its energy value. The GC then compares this value to the Cal Gas Cert CV and determines if the calibration gas' energy value is within the CV Check Allowed Deviation. If it isn't, the GC triggers the Energy Value Invalid alarm.

The following conditions must be met before the GC can perform a EV Check:

• The EV Check flag in the System window must be enabled.

• At least one stream must be set up in the Streams window as

a calibration stream and the Auto flag for this stream must be enabled.

The EV Check is performed under any of the following circumstances:

• During a warm start that follows a power failure during

normal operation. The GC waits for the heater and electronic pressure controller to reach their respective set points and stabilize. It then analyzes the calibration gas as an unknown stream and identifies the peaks. If all the component peaks are identified, the GC computes the calibration gas' energy value and performs the EV Check.

• After a successful calibration, the GC computes the gas'

energy value with the new response factors and performs the EV Check.

Application

Component This drop-down list contains the complete catalog of

available components for the selected stream.

Usr Std Indicates the source of the component:

• Usr - The component was edited or defined by the user.

• Std - The component was selected from the standard list

of components and no changes were made to its standard data.

Det # The component’s detector number.

Ret Time Time in seconds before the apex of the component’s peak will

appear. The rentention time can be set from 0 to 3600 seconds.

Application

CAUTION!

Ensure that the component retention times do not exceed the analysis time, as defined by the Timed Events table. MON2020 does not automatically prevent the user from defining excessive component retention times.

Resp Fact A component’s response factor is equal to the raw data of the

component’s peak divided by the component’s concentration. The maximum value is 1.0E+38.

Calib Type MON2020 can perform four types of calibrations:

• Single-Level - Uses the standard calibration in which the

response factor is needed to determine the mole percentage during the calibration.

• Fixed - During the calibration, the response factor is not

updated.

• Relative - Calibration in which a reference component is

used to compute the mole percentage.

• Multi-Level - Uses a polynomial equation to compute the

mole percentage during the calibration. Values must be entered in the Mult-level Calib ‘a’, Mult-level Calib ‘b’, Mult-level Calib ‘c’, and Mult-level Calib ‘d’ cells.

Calib Conc The amount, in mole percent, parts per million (ppm) or parts

per billion (ppb), of the component that is present in the calibration gas.

Unit Indicates the unit of measure used when calculating and

displaying the component’s calibration concentration. Options are Mole%, ppm and ppb.

Anly Meth Defines how the component concentration is computed. The

analysis method can take one of the following values:

• Area - Calculates the component concentration by

dividing the peak area by the response factor.

• Height - Calculates the component concentration by

dividing the peak height by the response factor.

• Fixed - The component concentration equals the

component's calibration concentration displayed in the Calib Conc column of the component data table. No calculation is performed using the response factor.

• Analog Input - The GC reads the analog input channel,

scales the raw milliampere value to engineering values that were set in the Analog Inputs window, and uses this value as the component concentration. No calculation is performed using the response factor.

RT Secs Dev The maximum acceptable deviation time, in seconds, of the

new retention time from the current retention time.

4.2.6 Change the default C6+ mixture ratio

The C6+ component that is detected by the GC is actually a mixture of up to four heavy hydrocarbons -- from hexane and above. When the energy value and other physical properties are calculated for the mixture, the GC assumes a ratio of heavy hydrocarbon components is used for the C6+ value. By default, there are four pre-defined ratios:

Component C6/C7/C8 percentages

C6+ 47/35/17 47.466/35.34/17.194

Application

TEV Type

The type of integration event. You have the following options:

• Inhibit: Set to Off to start look for a peak; set to On to stop looking for

a peak.

• Integrate: Set to On and Off to set a region in which the area under

the trace is computed as a peak regardless of peak onset discovery. The resulting area is added to the raw data as a peak with the retention time set to the Integration Off time.

• Summation: Set to On and Off to set a region in which the area of all

peaks found will be added together to create a single summed value. The peaks that contribute to the summation are marked as partial peaks in the raw data table, and the summation total is added to the raw data as a new peak with the retention time set to the Summation OFF time.

• Slope Sens: The peak starts when the slope of six consecutive points is

greater than the slope sensitivity value that is displayed in the Value column; the peak ends when the slope of six consecutive points is less than the slope sensitivity value that is displayed in the Value column.

• Peak Width: Each point displayed on the graph represents the

average of N raw data points, where N is the value displayed in the corresponding Value column.

• Single Base: Determines how the baseline is drawn under a peak.

- Off: The baseline is drawn from the point of peak onset to the

point of peak termination. This is not necessarily horizontal and if fact usually has a slight slope. (Default)

- Bgn: Draws a horizontal baseline from the point of peak onset to a

point above or below the peak termination.

- End: Draws a horizontal baseline from a point above or below the

peak onset to the point of peak termination.

• Fused Ovrrd: Determines how the baseline is drawn when two or

more peaks are ‘fused’ together.

Application

- Off: A single baseline is drawn from the onset of the first peak of

the fused group to the termination of the last peak of the group. (Default)

- On: Causes a separate baseline to be drawn for each peak in the

fused group.

• Negative Peak: Determines whether peak detection will detect

inverted peaks, which are peaks that point downward from the baseline. At any given moment we can detect positive or negative peaks but not both at once.

- Off: Detect positive peaks. (Default)

- On: Detective negative peaks.

TEV Type

SW Auto Zero: Re-zeros the baseline of the trace at the specified time for the specified detector. Used after a FID gain change event or a spectrum gain change event.

1. Select Timed Events... from the Application menu.

The Timed Events Tables selector window appears, displaying a list of available timed events tables.

Note

Other ways of accessing the timed event tables are by pressing F5 or by clicking the Toolbar.

Note

If only one timed events table is available, it will display immediately, bypassing the Timed Events Tables selector window.

2. Select the table that you want to view.

from

The selected timed events table displays.

Application

Note

To sort events by time, click the appropriate Sort button.

3. If you want to add the event above the currently selected event, click the appropriate Insert before button. If you want to add the event below the currently selected event, select Insert after from the Insert arrow and then click the button.

The new event will be added to the table.

4. Select a Type, Valve/DO#, and State for the event, if necessary, and enter a new Time for the event also.

5. To save the changes and close the window, click OK.

Note

To save the changes without closing the window, click Save.

4.4 The Validation Data Tables

Use the validation data table to hold information about the composition of the gas that is used in the validation run. During a validation run, the GC performs a test analysis of a gas with a known component composition to verify that the GC is working properly.

To add a component to the validation data table, do the following:

1. Select Validation Data from the Application menu.

The Validation Data window displays.

2. If the appropriate table is not displayed, select it from the Choose Table drop-down list.

3. Select a new variable by clicking on the appropriate drop-down list under the Variable column.

For a demonstration of how to use the context-sensitive variable selector, see

Section 1.11.

4. Enter the component’s concentration percentage in the appropriate cell under the Nominal Value column.

To ensure accuracy, this value, which is compared to the GC’s analysis results at the end of the validation run, should be taken from the documentation provided with the gas cylinder.

5. Enter a value in the appropriate Percent Deviation cell.

Example: If you enter 10 in this field, and the GC’s analysis result for the component differs from the component’s Nominal Value by ±10% or more, then an alarm is generated.

6. To copy a component variable to the next empty row, click C + Copy.

The component will be increment to the next available component—for example, from Ammonia to Benzene. The Nominal Value and Percent Deviation values will also be copied.

Note

You can select and copy more than one component at a time.

If there are no components available, instead of copying the component, MON2020 will display the following message:

7. To save the changes and close the window, click OK.

4.5 Calculations

MON2020’s Calculations submenu allows you to activate and define how the output of standard or user-defined chromatograph analysis data is used in various calculations.

You can configure the following types of calculations:

• Control - Allows you to designate, by streams, the standard calculations that should

be performed from the analysis data.

• Averages - Allows you to designate, by streams and components, averages of

standard calculations MON2020 should perform.

• User Defined - Allows you to create and edit customized calculations using analysis

data. See Appendix A for more information.

• Dewpoint - This optional feature allows you to calculate dewpoint temperatures

and to estimate the cricondentherm, which is the temperature above which no liquid will form at any pressure.

4.5.1 Set standard calculations by stream

To designate, by streams, the standard calculations—for example, mole percent, liquid volume, gas density, Wobbe index, etc.—that should be performed from the analysis data, do the following:

1. Select Applications → Calculations → Control....

Application

The Control Calculations window appears.

2. Select a check box for a given stream to turn the calculation ON for that stream; click to clear the check box for a given stream to turn the calculation OFF for that stream.

You can use the arrow keys to move from one stream cell to another, and you can press the space bar to toggle the calculation on or off.

3. To save the changes and close the window, click OK.

Note

To save the changes without closing the window, click Save.

Note

To save the information on this screen to a tab-delimited text file, right-click on the table and select Save Sheet from the right-click menu.

Note

To copy the information on this screen to the clipboard so that it can be pasted into another application such Microsoft Word or Excel, right-click on the table and select Copy to clipboard from the right-click menu.

Note

To print the information on this screen, right-click on the table and select Print Sheet from the right-click menu.

4.5.2 Edit average calculations

To designate, by streams and components, averages of standard calculations the GC should perform, do the following:

1. Select Applications → Calculations → Averages....

The Averages Calculations window appears.

2. Select a new variable by clicking on the appropriate drop-down list under the Variable column.

For a demonstration of how to use the context-sensitive variable selector, see

Section 1.11.

Note

The averages will be assigned in the default Modbus map in the order that they appear in the table.

3. Select the type of average to be calculated from the Average Type drop-down list. You have the following options:

Unused An average will not be calculated for the variable.
