In the time program of the conductivity detector, the amperometric detector and the UV/VIS detector, the Measuring time can be defined using aformula in the Measure noise command.
In the time program of the conductivity detector, the amperometric detector and the UV/VIS detector, the Measuring time can be defined using aformula in the Measure drift command.

3 Improvements
GeneralPerformance optimization￭

Performance improvements are available from MagIC Net 4.2. A client/server system also functions stably if the server is not located in the internal
network, but rather in a remote data processing centre, for example, or if
the network latency is increased.
Existing databases and methods must be migrated into another data format
to improve performance. The migration can be started via the databasemanagement or the method manager.

New look and feel￭

MagIC Net 4.2 has a new look and feel. The new look and feel improves
the scaling and sharpness of the user interface on 4K monitors.
It is now possible to choose between a light and a dark display. Operation
has not changed.

Database program part
Database backup monitoring￭

2

An additional status has been introduced for monitoring the databasebackup. If it is unknown whether a due database backup has been successfully performed, then the database will be highlighted in orange in the database management. This status is used, for example, when a backup is running.
The [Updating] button has been newly added. The status of the databasebackup can be updated with [Updating]. The database marking is adjusted
accordingly.

8.0102.8017EN / v1 / 2023-06-30

Method program part

4 Fixed bugs
GeneralMaximizing the window￭

If work was done with multiple screens and MagIC Net was not open on
the primary screen, then MagIC Net was moved to the primary screen when
the window was maximized.

Print data￭

If a user did not have the necessary permissions for directories, the printingof files (e.g. determination overviews, security settings) caused MagIC Net
to crash.
The document MagIC Net 4.2 Installation (8.0102.8016) contains information on the desired permissions.

Workplace program part
Dosino gradient before injection with 889 IC Sample Center￭

When executing a method with the following commands in the following
order, an exception wizard appeared:
1. Dosino gradient
2. Injection with a 889 IC Sample Center

Loss of tasks￭

If tasks were defined in the Timer dialog and then the colour of the workspace was changed in the Workplace properties dialog, then the definedtasks were no longer available.

Database program part
UTC in reports￭

In reports, the time at which the report was generated is specified withCoordinated Universal Time (UTC), e.g. 14:30:10 UTC +1.

Variables￭￭

8.0102.8017EN / v1 / 2023-06-30

The result of the CALRSE variable was not correct.
The result of the FIN sub-program variable was incorrectly invalid in rarecases.

3Column names during recalculation￭

If the upper/lower case of a column was not consistent in the configurationand in a method, then the Theoretical plates per meter had an invalid
result after recalculation.
The upper/lower case of column names is now disregarded.

Conductivity detector serial number￭

In determinations with a conductivity detector with a serial number thatbegan with 0, the serial number was displayed under Database ▶ Information ▶ Devices without 0.
Example: Serial number according to configuration: 01101
Serial number according to Database ▶ Information ▶ Devices: 1101

Method program part
Method import￭

If a method was imported with a time program command Dosino gradient in MagIC Net and if the solution for the Dosino gradient was named
differently than on the system on which the method was created, than anerror would result.

Duplicated tabs￭

If a device was added in a method via Add ▶ Device ▶ New device, anda device of the same type and with the same device name already existed in
the configuration, then some tabs would duplicated in the method.
The following devices and tabs were affected by this error:– Sample changer with 2 towers, e.g. 815 Robotic USB Sample Processor XL: Peripherals tower– 889 IC Sample Center: Cooling, Injector– Multi EA Combustion Module: LPG/GSS– Devices with analog outputs, e.g. 891 Professional Analog Out: Out
1 to Out 4

Variables￭￭

The result of the CALRSE variable was not correct.
The result of the FIN sub-program variable was incorrectly invalid in rarecases.

Measuring conductivity￭

If a method contained 2 commands Measure conductivity and the difference was calculated, the following behavior occurred: If the warning limit
was set to 9,999 µS/cm or less, then the difference was calculated correctly.
If the warning limit was set to a value above 9,999 µS/cm, then the difference was calculated incorrectly.

Corrupted passwords￭

4

If authentication is enabled in the e-mail template, an encrypted password
must be entered to send e-mails. In rare cases, the password has been corrupted. Not all digits were shown when a corrupted password was displayed.

8.0102.8017EN / v1 / 2023-06-30

Missing error messages￭￭

No error message appeared if the UV lamp of 947 Professional UV/VIS
Detector Vario failed to ignite.
If a method with a combustion module contained the Combust time program command with the Flame sensor option and the flame sensor was
not connected, then the time program would crash with the affected command. No error message appeared.

Configuration program part
Port for e-mail notification￭

In the Send e-mail window, changes in the Port field were not saved
when closing the window despite confirmation with [OK]. The value in thePort field was reset to the default value. The window is reached via
Tools ▶ Security settings ▶ Login/Password protection ▶ E-mail....

Manual program part
Missing error message￭

No error message appeared if the UV lamp of 947 Professional UV/VIS
Detector Vario failed to ignite.

5 Known bugs
Method program partStatistics￭￭An error is displayed if the CONCMEAN variable is used as statistics function.
Correct procedure: Use the CONC variable only as a statistics function. To
calculate the mean value, select Mean value in the Define statistics dialog.
If the CONCMEANSD variable is used as statistics function, the results areoutput as invalid during reprocessing.
Correct procedure: Use the CONC variable only as a statistics function. To
calculate the standard deviation, select Standard deviation in the Define
statistics dialog.

Tandem dosing￭

8.0102.8017EN / v1 / 2023-06-30

Tandem dosing requires 2 dosing units. Dosing unit A doses until it is empty.
Then dosing unit A is filled. In the meantime dosing unit B doses. In thenext row, dosing unit A starts again with dosing. Each dosing unit doses
until it is completely empty and is then filled again. So it can happen thatboth dosing units are empty at the same time. If dosing cannot be carriedout correctly, the mixing ratio of the gradient changes. To avoid this, program the method in such a way that dosing unit B is filled in the beginning
or in the end of each determination.

5

Monitoring￭

Common variables cannot be used for monitoring. If common variables areused for monitoring as Upper limit and Lower limit in a method, thenthe limits in a running determination are invalid.

Database program part
Temperature specification￭￭

For 930 instruments without oven, the Analyses tab in the Information
subwindow shows a temperature of –22.8 °C.
If no column is defined for the analysis in a method, but a temperature isdefined for the device, then the Analyses tab in the Information subwindow shows no temperature. Therefore always assign a column to theanalysis.

Monitoring￭

A lower limit and an upper limit are defined for monitored determinations.
If the result is outside of the defined limits, then a message is displayed on
the Messages tab in the Information subwindow. If the determination isthen recalculated with changed limits and the result is within the limits,then the message will nonetheless be displayed.

6 Compliance
The current software version does not contain any modifications that affectconformity of MagIC Net regarding 21 CFR Part 11 or its classification into theGAMP software category.
