Analog-Digital Converter, this electronic components are used to digitize analogous measuring-signals and make them readable to microprocessors. Depending on the required accuracy the digitizing is performed with 8, 16 or 24 bit resolution.

Dragging is used to move an object on the screen from one location to another. Dragging is also used to resize an object by moving the objects border. Click and hold down the mouse button to move or resize an object.
A focus is a visible border or color-effect emphasizing preselected controls
A filter is used to prevent invalid character-input. The set of valid characters are usually annotated with rectangular brackets, for instance
[0-9], [ASCII 32-127]
Final-Values are the result of the signal-postprocessing. Post-processing is used for data-correction by applying calibration-values, or if the use of different technical units is required for data-evaluation (i.e. ppm versus µg, or m/sec versus km/h).
A Graphical User Interface (GUI) allows the user to interact with the system in a shophisticated way.
Halfhour-Meanvalues (HMV) are the result of the standard data-processing. The environmental monitoring system is capable to store up to 21 days of HMV for up to 48 components.
A component may be a physical or a logical component. For instance the wind-gust is described by 3 logical components: wind-gust, related wind-direction and related time-marking of the occurence.
A progress-bar is an indicator showing the progress of timeconsuming operations
Raw-Values are the result of the signal-conversion - the electrical input-signal is converted in technical units by use of a polynomial. For instance the signal-voltage of the temperature-sensor is converted in °Celsius.
RS-232 is a communication-link used for data-transfer over short distances (suitable for up to 15 meters of cable-length).
The sub-identifier is used to distinguish devices of same type. The unique Device ID consists of two digits describing the type of measuring device (ie. temperature sensor = 13) and a sub ID from 1 - 9.
The task-bar is used by the operating system (ie. Win98, WinNT) to indicate running user-applications. A small part of the task-bar is provided for system-activities, for instance time-display.
A hooverhelp or tooltip is used to explain abbreviations or technical expressions
A User Password is required to access data or execute operations
Variable-Meanvalues (VMV) are the result of user-defined data-processing. VMVs may be established for up to 8 components. The storage of VMVs depends on the number of components and the choosen time-interval.
The environmental monitoring system is capable to store exactly 3 days of VMV for 8 components with measuring-intervals of 1 minute. If the number of components is decreased, or the time-interval is increased, the storage-capacity will increase accordingly.

Station Parameter
Introduction
The station parameters determines the identity and behaviour of the environmental monitoring station. These parameters comprises unique station identifiers, communication-settings like telphone numbers and modem-types, alarm recognition and alarm-schedules.
Overview
The Station Parameter view is a tabbed pane divided into four editable tables. Each table contains a set of parameters. Click on the overview-list to see a short description to each parameter-table.
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.
|
Parameter Editing
The third column (titled Parameter New) contains editable entryfields which allows you to edit the parameter-value. Doubleclick into the entryfield and make your changes.
 | Entryfields are usually combined with filters to prevent invalid data-input. If a filter is applied with an entryfield, the set of valid characters 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
Parameter-table 1 contains parameters to specify the identity and communication settings of the environmental monitoring station:
Station ID Setting of station name and number
Communication Setting of telephone and Datex-P numbers
TimeoutsSetting of communication and retry-timeouts
Time Sync Specifies maximum time difference with the central measuring system
|
Parametertable 2
Parameter-table 2 contains parameters to specify the communication device and the handling of error events:
Transmission mode Select modem, leased line or data-island
Error Message Mask Setup internal error-message generation
Error MessagesSetup retries and blocking-times
|
Parametertable 3
Parameter-table 3 contains descriptive parameters which explains the meaning of status-bits in plain text:
Software Status The meaning of Software Status-Bits
Hardware Status The meaning of Hardware Status-Bits
|
Parametertable 4
Parameter-table 4 contains parameters to specify emergency schedules:
Alarm RelaysConfigure emergency shutdown relays
Alarm Schedule Setup emergency shutdown schedule
|
Menu
The Station Parameter Menu is used to transfer the configuration parameters from and to the environmental monitoring station and to copy the configuration to a backup-archive (harddisk or floppy).
A usual approach to setup a new environmental monitoring station is to load a prepared or a standard configuration from your backup-archive, set the proper station ID and station-name with the Servicetool and save the configuration to the station.
File Dialog
The look and behaviour of the file-dialog depends on the operation system of your Service-Tool PC. The example shows a file-dialog used with the operation system MS Windows.
