Software usage and features overview
---------------------------------------

1. User roles can be changed by clicking on the user profiles icon on the panel on the left side of the screen.
- The default user role is ReadOnly. It doesn't allow the user to update data on the pump. It doesn't require a password.
- The main user role is Customer. It doesn't require a password and offers the ability to upgrade and configure the pump in standard usage scenarios.
- The Service and Developer roles are for performing advanced upgrades and diagnostics and are typically for internal use.

2. The software will automatically scan ports, every few seconds, at startup and after a pump disconnection event is detected (e.g. if a cable is removed).
- It will then automatically connect to a pump (if only one pump option was identified).
- If more than one pump option was identified as being available for connection purposes, the user should manually click on one option to select it.
- If more than one pump option was identified then the user can click on the pump option that they wish to be the currently active and selected one.
- When a pump has been selected, it will be highlighted in blue), and the auto device scan will pause.

3. There is a manual device scan button on the left panel.
- This will result in an immediate rescan of available ports for connection purposes and will refresh the display.
- In most usage scenarios this option is not necessary.
- It can sometimes be useful to refresh the display if connecting or disconnecting multiple device to ensure the displayed pump options are up-to-date

4. The Pump Operations page provides key control options and status information for the currently active (selected) pump.
- The Pump Commands view allows the user to issue a command to start, stop or enter standby mode. Some pumps will also show a Close Vent Valve option.
- The Alerts Summary allows the user to see a snapshot of active warnings and errors. If the icons are greyed out then there is no current info available.
- Double clicking on a coloured (non-grey) icon for errors or warnings in the Alerts Summary will jump to the Alerts page for more detailed info.
- The Pump Status section shows some indicators of current status values reported by the pump for acceleration, deceleration, alarm active and speed notifications.
- The Normal Speed, Ramp Speed and Overload Speed are all standard indicators that you would expect to see light up as the pump accelerates towards full speed.
- The Key Parameters section features gauges showing the values of a few key parameters, applicable to the currently active pump.
- The Key Parameters display will show the words Pump Disconnected whenever a disconnection event is detected (and at startup for some seconds).

5. The User Configuration page allows the user to read and update key user configurable parameters (where applicable to the pump).
- Press the read button to refresh the display of user configurable parameter values.
- Press the edit button to change parameters. Select the parameters that you wish to change and modify their values.
- Press the cancel button to abort an editing session without updating the data on the pump.
- Click on the apply button to write the changes made back to the pump.
- Parameters can only be viewed in the ReadOnly (standard) user level.
- The Customer and above user levels allow the user configuration parameter values to be edited and applied.
- File load and save options are also available to store and restore configuration settings that are used repeatedly.

6. The Operational History page allows the user to view and update operational history data on the currently selected pump.
- Press the edit button to change the values of some editable parameters. Select the parameters that you wish to change and modify their values.
- Press the cancel button to abort an editing session without updating the data on the pump.
- Click on the apply button to write the changes made back to the pump.
- Click on the Reset buttons to reset minor service, major service or run-time data (where applicable to the user level and current pump).
- File load and save options are also available to store and restore values that are used repeatedly.
- Parameters can only be viewed in the ReadOnly (standard) user level.
- The Customer can generally reset service counters (available options vary according to the pump).
- The Service user can update pump identity and most operational history parameters (where applicable to the pump).

7. The fault log page provides options to read faults from a connected pump and save the fault log records to local storage.

8. On the Data Monitor page the user can log to file and plot values on a chart the values of selected parameters at periodic intervals.
- A table data view is also provided to show values for file logging on the screen as they are updated, for dynamic monitoring.

9. The Flash Upgrade page allows the user to upgrade the software and/or parameter sets on a connected pump/drive.
- The middle column on the initial Device Info view shows the current pump configuration.
- The right hand column on the Device Info view shows the current release.
- The current release means the latest proposed variant stored by the tool, which is compatible and is available for upgrade.
- If proposed software or parameter sets are marked as green in the current release field on the upgrade page it means that the current software is up to date.
- The current release will be coloured in red if the currently installed version on the pump is behind the latest stored version which is available for upgrade.
- Manual upgrades can be done via the manual file selection buttons (for service users or developers). An upgrade file can be chosen from a file selection dialogue.

10. The Data Sync page allows the user to initiate a check for pump/drive software and parameter set updates.
- Once a data sync is initiated, it will download available software and parameter set file releases for supported pumps.
- Performing a data sync requires an Internet connection but the software can be used offline when not performing this function.
- It is recommended to perform this operation from time to time to get the latest set of files which have been released for pump upgrade purposes.

11. The Fault Log page allows the user to read faults from the connected pump and store the fault log records locally for later inspection.
- The Full Log section shows a bulk summary of all data retrieved from the pump in a formatted form.
- The Selected Log section allows the user to see individual faults.
- Individual faults can be selected from the pulldown list and can be traversed through using the fault log traversal buttons.

12. The Alerts page provides a snapshot of alerts such as warnings and errors and the view is updated dynamically on a periodic basis.
- The Active flag for paticular alerts can be unselected and then pressing the Show Active Only button will remove stale alerts from the display.

13. The BCON page allows the user to initiate, stop and monitor the bearing conditioning process (available for nEXT730/930 pumps).

14. The Parameter View page provides a grid showing a list of all applicable and relevant registers for the currently selected pump.
- This page is only available to the Developer user level.
- The user can select some or all of the available registers to see their raw/unscaled values for testing and diagnostic purposes.
- The data values of the registers that have been selected can be updated on the display by pressing the refresh button.

15. Communication Settings can be changed by clicking on the Comms... button on the status bar.
- This window displays the Active Device ID and Active Baud Rate when a pump is connected.
- The user is able to modify the Device ID (hint) and actual Baud Rate to use during the device scan.
- The minimum and maximum range for Device ID can be set which specifies a range of device IDs to use in the device scan.

16. The About button on the status bar displays the details about the current nST2 application.
- Product information such as the installed application version is displayed.
