Uwedat® Servicetool

The environmental monitoring station is equipped with a number of measuring-devices (components) and each device is described by a set of parameters. The equipment and the parameterization is designated with the term configuration. The Device Parameter work-view is provided to manage the configuration. The device-menu includes controls to install and remove measuring-components, to manipulate parameter-sets and to start and stop the measurement of individual components. The device-parameter determines both the characteristics and behaviour of the measuring-components and the data conversion of the measured values.

Overview

The Device Parameter view is a tabbed pane divided into five editable tables. Each table contains a set of parameters, the tables are selected by click on the table-tab. If you want to view the parameter-set of a component, you must specify the component. You can enter the component-number directly or you can use the Device-Selector

Device Selector

The Device Selector is a external, floating window which is always on the top of the work-view window. The device-selector shows both the equipment (device-inventory) and the state of the individual devices (measuring, idle, edited). A device is selected via mouse-click, and unambiguous user-actions can be started with double-click.

The Device Selector is used with a couple of user-actions. For detailed information see Device Selector .

Parametertable

The parameters are grouped into three columns. The first column shows the meaning of the parameter and the second column shows the value of the parameter. The third column contains editable datafields which allows you to edit the parameter-value.

You can always view the parameter-set of individual components, but any changes to the parameter set are denied unless the measurement of the component is stopped (command Device Off).

Parameter Edit

The third column (titled Parameter New) contains editable entryfields which allows you to edit the parameter-value.

Entryfields are usually combined with formatters to prevent invalid data-input. If a formatter is applied with an entryfield, the used [formatting-rule] is described in rectangular brackets. It is important to know, that such entryfields doesn't accept data-input which violates the formatting-rules.

Parametertable 1

The parametertable 1 comprises common device- and signal-parameter. For detailed information see Parametertable 1.

Calculationtable

The calculation table gives the possibility to autocalculate the conversion parameters by the prior selected profile number, measuring range and manually edited device ranges. For detailed information see Calculationtable.

Parametertable 2

The parametertable 2 comprises parameters for signal conversion and signal tolerances. For detailed information see Parametertable 2.

Parametertable 3

The parametertable 3 comprises parameters for data evaluation (mean values) and data-qualifying. For detailed information see Parametertable 3.

Parametertable 4

The parametertable 4 comprises the description of individual bits of device-statusbyte, device-errorbyte and HMV -statusbyte. For detailed information see Parametertable 4.

Parametertable 5

The parametertable 5 comprises parameters for device calibration. For detailed information see Parametertable 5.

The Device Parameter Menu is used

to manage the equipment
(install and remove devices)

to change the state of devices
(measurement On, Off)

to load, manipulate and save device parameters

to copy device parameters to a backup-archive (harddisk or floppy)

All menu-actions requires the preceeding selection of one or multiple devices.

Main Menu ButtonQuit the Device-View and returns to the Main-View.

Help ButtonCalls the online-help for the Device-View (this chapter)

Device Number This entry-field is used to specify one single device directly by component-number. If you don't know the approbiate component-number, use the Device-Selector button

to open the Device Selector . The Device Selector can also be used to make multiple selections at once.

Device ON Switches the measurement-state of the selected device to On (measuring). Multiple device-selections are allowed for this function.

Warm ON Switches the measurement-state of the selected device to On (measuring). No Startup-calibration and no warmup-procedure. Multiple device-selections are allowed for this function.

Device OFF Switches the measurement-state of the selected device to Off (idle). Multiple device-selections are allowed for this function.

Install Installs a new device. Requires a new unique component number. The install will be denied if the component-number already exists. This function is not applicable for multiple device-selections, you have to install devices step by step.

A usual approach to setup a new device is to load a prepared or a standard device-configuration from your backup-archive, set the proper device number and device-name whith the Servicetool and save the configuration to the station.

Delete Removes an existing device. The device must be "switched Off", otherwise the removing is denied. Multiple device-selections are allowed for this function.

Load Button Load the parameter-set of the selected device from the environmental monitoring station into the Servicetool and display them. Multiple device-selections are allowed for this function.

Save ButtonTransfer the (edited) parameter-set from the Servicetool back to the environmental monitoring station. Multiple device-selections are allowed for this function.

An usual approach to setup new devices is to duplicate the parameter-set from similar devices:

Install a new device with unique component-number

Load an existing similar device

Change the component-number in the parameter-table to match the new device

Select the new device with the Device Selector and save the parameter-set

Load File ButtonLoad a device configuration from a backup-archive (harddisk or floppy) to the Servicetool and display them. Use the file-dialog to select the approbiate file.

The backup-files for device-parameters usually have a filename which contains station-number and component-number "SnnnnKnnn.par" (german K for component!). Multiple devices usually stored with the filename "SnnnnKXXX.par".

EXAMPLES:
s1234k011.par = Component 011 from station 1234 s1234kxxx.par = Multiple components from station 1234

Save File ButtonSave the selected device-configuration to a backup-archive (harddisk or floppy). Use the file-dialog for subdirectory-selecting. A default-filename for the backup-file will be suggested (a combination of station-number and component-number with the file-extension "par").

You can always view the parameter-set of individual components, but any changes to the parameter set are denied unless the measurement of the component is stopped (command Device Off).
