Program LBX is a part of a control-measurement system of any complexity. It is responsible for communication with the control measurement devices and creates a user interface, which allows on data presentation and makes available various control mechanisms.
The program itself is divided into two parts: a server and a client that assure a possibility of remote operation – using available mechanisms of network communication can be from any remote place conducting data monitoring and device control. The program has a possibility of work without using the network transmission (local) – in such case it creates one entity immediately serving the devices and making available the user interface.Server functions:
Communication between a client and a server is performed using the
transport mechanisms of the computer networks- typically it is a
Access to a domain (LBX server) is subjected to authorization for
each client separately. For each system user an account is required,
for authorization the user names and passwords are used. With each user
certain authorizations are associated that one can exercise, allowing
on limiting its possible work functions (typical authorizations are:
data monitoring, changes in settings, changes in configuration,
administrator). Each remotely controlled access to a server is
registered, there is also a possibility of monitoring who currently is
connected to the server.
The program serves a wide scope of devices produced by the LAB-EL
company, as well as some other devices. The list covers the meters (
LB731), regulators (
LB760C), meteorological stations (
LB741), GSM modems of various type,
Ethernet/serial converters of various type, all devices with a MODBUS
interface, an Ethernet camera.
The program’s open architecture allows on very simple extension of its functionality for any other devices.
The program introduces all available values (measurement results, settings etc.) from all types of devices in a form of a variables of unique names. The variables in such form are subjected to registry to data archive where they are then available for presentation in a form of graphs of reports in a uniform way independently from a source of origin. Each variable can be monitored independently and placed on a cumulative screen in any configuration with the other variables. For each variable also an alarm can be set.
The program presents data in various ways. For each device typically
available is an individual status screen on which all data concerning
that device is collected. For some devices, when there is
simultaneously a greater number of them, the program allows on
displaying cumulative screens, grouping data from all devices. A user
also has an option of creating the cumulative screens in any edited by
oneself configuration. On such screen it is possible to place each
variable available in the program, presented in various ways: numerical
reports, a graph, a meter, a control on/off).
The program keeps data archive to which data readouts go (variables) from the undertaken registries. The archive is run on a server where simultaneous access to it have any number of clients. Data readout from the server archive to a client is optymalized - a client keeps his own work copy of data, reading only such data that one lacks. It allows also on access to that data at the side of a client in case of lack of connection with a server. Data archive can be configured in such way, so it stores only data not older than a set period of time, preventing excessive increase in volume of such data. Data from the archive can also be periodically stored to separate copies, with which the program does not have to deal with any more – for archive purposes on solid data carriers by a user. The archive files have a correctness control, allowing on detecting file modification made externally. For assuring data security the files can also be enciphered by the program, requiring a password during readout.
For data presentation from the archive, the program allows on making a graph, a report or a histogram out of them with wide configuration possibilities. Data can be also exported to CSV files.
The program assures alarm monitoring both generated by the attached
devices, as well as set in the program-for different variables in a
form of the alarm thresholds. Each occurrence associated with alarm
appearance or fading is registered, additionally it can be associated
with any action:
The program works correctly on any contemporary PC computer, on which Windows 2000, XP, Vista, 7 (versions of Windows 95/98/Me and NT4 are not supported). The minimum computer requirements are the same as for correct work of a given operation system. Recommended is minimum 512 MB RAM.
For each client, who purchased any device produced by the LAB-EL
company we made the program LBX available charge free.
In order to obtain the program, one should send in any form (i.e. an e-mail) an order with data about the purchased devices (invoice number, types and numbers of the purchased devices) that are to be served by the LBX program in client installation and personal contact data (name, last name, telephone, e-mail) of a person responsible for installation.
To a provided e-mail a license for the program LBX will be sent along with the authorization keys. Each client can make use of the promotion once, receiving a right to use the program LBX for 3 months from a date of order.
