1 Introduction

1.1 Overview
LWEB-900 is an innovative and comprehensive solution for building management. The
software covers the whole sequence of activities, from installation of the building
management system through configuring the devices, all the way to daily operation of the
facilities. Thus, a common user interface is available at all phases of the project.

Figure 1: LWEB-900 Client User Interface

The central component is the LWEB-900 Server, which stores all configuration data in a
database and communicates with the devices of the building management system in real
time. The LWEB-900 Client is the user interface of the building management system. When
a user starts the client, he has to log on to the server before receiving access. Client and
server exchange data using web services only. Due to this system architecture, remote
access is easily possible through firewalls and NAT routers. In addition, differences
between the various field bus technologies (CEA-709, BACnet, DALI, MBus, Modbus,
KNX, etc.) are compensated and the user is presented with a consolidated view of the
separate systems.

Version 1.3 LOYTEC electronics GmbH

LWEB-900 User Manual 10 LOYTEC

Figure 2: LWEB-900 System Architecture

To operate and monitor the building technical equipment a standard web browser can be
used. In this way it is possible to quickly check the status of the building automation system
while travelling. It makes no difference, whether a smart phone, tablet, or PC is used.
Compared to the LWEB-900 Client, the functionality of the web application is limited to
the daily operation of the building and does not include the functionality to install and
configure the system.

Figure 3: Graphical View on a Mobile Device

1.2 Operating and Monitoring

In LWEB-900, all areas of a building are visualized and operated using installation
schematics. Each schematic can consist of a large number of dynamic display elements
which reflect the current status of the facilities. These display elements also include
complex elements like alarms, trend logs and schedules.

Version 1.3 LOYTEC electronics GmbH

LWEB-900 User Manual 11 LOYTEC

The configuration software to design the graphical representation of the installation is built
directly into LWEB-900. It allows users to easily create dynamic graphics without requiring
any programming knowledge.

1.3 Device Configuration

LWEB-900 manages and configures all LOYTEC devices based on a central database. The
set-up of the devices can be changed very comfortably because the required configuration
software is built directly into LWEB-900. It is also easily possible to update the firmware of
all devices and to perform backups.

1.4 Global Connections

With LWEB-900 it is easy to connect data points of different LOYTEC devices. For this
purpose, a global connection can simply be created and drag&drop can be used to add input
and output data points. LWEB-900 configures all devices which are part of the global
connection accordingly. After the connection has been configured, the devices exchange
data directly over TCP/IP.

1.5 Parameter View

The parameter view allows configuring operational parameters, which are distributed over
multiple devices, efficiently. For example, parameters for room temperature control, light
control, or sunblind control can be organized in different parameter views. Each parameter
view is a matrix where each cell represents a parameter. Parameters can be organized freely
in the matrix depending on space layout and function. In this way, it is possible to e.g.
adjust the running periods of sun blinds across many rooms with a few mouse clicks and
write the new values reliably into the corresponding automation devices.

1.6 Alarming
With LWEB-900, alarms from different sources can be visualized and managed in a
uniform manner. For example, an L-DALI device can generate alarms in case of a ballast
failure or if the emergency light test fails. On the other hand, a L-INX device controls the
air handling unit and triggers an alarm if the V-belt is torn or if the air filter is dirty. In
LWEB-900, these alarms are presented in a common view and the user can acknowledge or
disable them.

When an alarm occurs, one or multiple receivers can be notified via e-mail. A scheduler can
be used to control who is notified about alarms at a specific date and time. If the alarm is
not acknowledged within a configurable amount of time, an alternative action can be
triggered.

1.7 Scheduling
Schedules can be either executed in LOYTEC devices or directly in the LWEB-900 Server.
To optimize the reliability of the system, create schedulers at the same location as the
corresponding control logic. For example, an occupancy scheduler should be executed by
the L-INX automation controller which primarily uses this information, whereas a scheduler
determining which people are notified about alarms should be executed by the LWEB-900
Server.

Version 1.3 LOYTEC electronics GmbH

LWEB-900 User Manual 12 LOYTEC

LWEB-900 offers the unique possibility of organizing schedules in a hierarchical way,

independently of where they are executed. The resulting tree structure permits defining
entries which apply to all schedulers or only a subset. For example, a standard occupancy
schedule can be defined for a whole building. This global schedule can be modified for
certain areas of the building. The area specific entries can in turn be supplemented by room
specific entries.

After the schedule hierarchy has been defined, LWEB-900 calculates the resulting
configurations. If a scheduler is executed by in a LOYTEC device, LWEB-900 downloads
the configuration.

1.8 Trending
LOYTEC devices can record the value of data points over time. However, the memory
available on a device is limited. LWEB-900 overcomes this restriction by reading out the
trend data from the devices periodically and storing everything in the database.

A user can also create ad-hoc trend logs directly in LWEB-900. This is the fastest way to
create a trend log. One simply selects a data point and activates trending using the context
menu. LWEB-900 periodically polls the data point value from the device and stores the
value in the database.

Trend logs can be viewed either as tables or as charts. Especially for trend charts, a large
number of customization options are available.

1.9 Reporting
LWEB-900 can create reports based on trend logs. Reports can be used, for example, to
document the energy consumption in a building. The generation of a report can be trigger in
one of the following ways:

 Periodically: Reports can be generated daily, weekly, monthly, or yearly.

 Event: The change of a data point value can trigger a report.

 Manually: A report can be triggered manually by the user.

Reports can be generated in PDF, Excel, or Word format. They can be automatically
distributed via e-mail.

1.10 Multiuser System

LWEB-900 provides a separate work environment for each user. A user has to log on to the
system and is presented with a perspective tailored to his individual requirements. A
perspective defines which windows are open and how they are arranged. In this way, a user
can define separate perspectives which are optimized for different tasks and quickly switch
between them.

LWEB-900 uses access control lists to define which operations a user can perform on a
certain object (e.g. folder, data point, graphical view, parameter view, trend chart). To
speed up the access right configuration, access control lists can be inherited from parent to
child objects.

Version 1.3 LOYTEC electronics GmbH

LWEB-900 User Manual 13 LOYTEC

1.11 Event Log

All events are logged by LWEB-900 in the database. Events include alarms, alarm
acknowledgements, log-in and log-out of users, change of operational parameter, change of
device configuration, system messages, etc. The event log view offers a large variety of
filters to efficiently analyze all activities in LWEB-900.

1.12 Licensing
The license limits the number of devices which can be managed by LWEB-900. Different
license options are available starting with 10 devices up to an unlimited number of devices.

LWEB-900 User Manual 17 LOYTEC

LWEB-900 Server Schedulers

It is now possible to create schedulers which are executed by the LWEB-900 Server. They
should be used to schedule LWEB-900 Server user registers which trigger a report or enable
an alarm receiver. Refer to Section 6.14 for details.

Alarming

A number of features have been added to alarm management in LWEB-900:

 It is now possible to configure the priority of LWEB-900 system alarms.

 A custom filter can be configured for alarm notifiers.

 It is now possible to specify an enable data point for alarm receivers. By using a
user register which is controlled by a scheduler it is possible to configure different
receivers based on a time table.

 A column for the identification key of the data point which triggered the alarm has
been added to the alarm view. The identification key can also be added as a place
holder in an alarm notification template.

Create L-VIS project from LWEB-900 Server graphical view

It is now possible to simply copy an LWEB-900 graphical view to an L-VIS device. Refer
to Section 6.10.4 for details.

Allow wildcards in search expressions

You can now use the percent sign (%) as a wild card character in the search string. It
matches zero or more characters. For example, the search string “nvi%Fb” finds all data
points which have names starting with “nvi” and ending with “Fb”.

Hide folders to which a user has no access

The new option Show objects on which the user has no read access has been added to the
user configuration dialog. If this checkbox is enabled, the user sees objects (e.g. folders) to
which he has no read access. They are displayed with a lock icon. If this option is disabled,
those objects are not visible in the navigation and object list view.

Import and export Identification key schema

It is now possible to export the identification key schema from one LWEB-900 project and
import it in a different LWEB-900 project.

Datapoint details

A double-click on a data point displays detailed information about the data point (see Figure
5). The Links section shows where the data point is used. Click on a link to open the
corresponding view.

6.5 Add Devices

LOYTEC devices are added in the folder Network/Devices. To manage a large number of
devices, they can be grouped in subfolders. The LWEB-900 Server can communicate with
LOYTEC devices using one of the following modes:

 Web Service: This is the default communication mode enabling LWEB-900 to

access the full functionality of the device. The LWEB-900 Server uses web
services only (HTTP or HTTPS) for all communications with the device.

 TCP/IP: This communication mode should be used for devices with old firmware
versions which do not yet support web services for device management. It requires
that LWEB-900 can access the device using web services for real time data and
FTP/Telnet (or SCP/ SSH) to manage the device.

 E-Mail: Most LOYTEC devices can send an e-mail with a trend or alarm log in
CSV format in the attachment when a configurable fill level is reached. The
LWEB-900 Server can fetch these e-mails from a mail box and process the
contained data. This communication mode is a good option, if the device is behind
a firewall and cannot be accessed directly. Only history data (trend and alarm logs)
can be received from the device.

6.6 Configure Devices

Configuration Software

LOYTEC devices can be configured very comfortably because the required software can be
started directly in LWEB-900. The L-VIS, L-INX, and L-DALI Configurators are separate
software packages which can be downloaded from the LOYTEC homepage. When the
LWEB-900 Client is started, it checks which Configurators are installed on your PC and
displays any missing components (see Figure 37).

Figure 37: Device Configuration Software Not Installed

If the corresponding configuration software is installed, you can right-click on a device in

the navigation view and select Configure device.

Figure 38: L-VIS Configuration Software in LWEB-900

3. The new graphical view is created and displayed in the navigation view. Note, that a
data point interface folder is created below the graphical view.

Define data point interface

The data point interface folder contains all data points which can be used in the graphical
view. After creating a new project, the data point interface is empty. You can add data point
in one of the following ways:

Version 1.3 LOYTEC electronics GmbH

LWEB-900 User Manual 60 LOYTEC

 Pull data points from an object list view into the interface. A link to the original
data point is created.

 Drag a complete folder into the interface. In this case, a link to the folder is
created. If the contents of the original folder change (e.g. data point configuration
of a device is modified), the interface changes accordingly.

 Press the [CTRL] key while dragging a folder into the interface. The folder
including all its sub-folders is created in the interface and populated with data
point links.

You can create folders to organize data point and folder links by selecting New  New
Folder from the context menu.

Figure 57: Data Point Interface of Graphical View

Note Only OPC data points can be added to the interface of a graphical view. They are marked

6.10.3 Graphical View Templates

Use graphical view templates to create multiple graphical views with the same graphics but
referencing different data points. For example, you can create a graphical view template
which visualizes a room. This template can then be instantiated for each room in your
building. If you modify the template, all instances of the template will be updated.

Create new graphical view template

1. Right click the folder Library in the navigation view and select New  New
Graphical View Template from the context menu.

2. Enter a name and description for the graphical view template and click on OK.

3. Create the data point interface and the graphics in the same way as for a normal
graphical view (see Section 6.10.2).

Instantiate Template

1. Right click on a folder in the navigation view and select New  New Graphical View
from the context menu.

2. Enter a name and description for the graphical view.

3. Select the option Initialize from template and press the browser button to choose the
template. Click on OK.

4. Replace folder/data point links: Drag a folder/data point from a device in the Network
folder onto the folder/data point link in the data point interface for the template
instance.

Note Wherever possible, use folder links instead of data point links. A folder which contains
multiple data points can be relinked much faster than multiple separate data point links.

Version 1.3 LOYTEC electronics GmbH

LWEB-900 User Manual 63 LOYTEC

6.10.4 Graphical Views in LWEB-900 Server and in LOYTEC device

There are two types of graphical views:

 Graphical view in LWEB-900 Server: Graphical views of this type can be located
in any user folder in the navigation view. In order to display real-time data, the
graphical view communicates with the LWEB-900 Server using OPC XML-DA.
The LWEB-900 Server in turn communicates with LOYTEC devices using OPC
XML-DA. This approach has the advantage that it relieves the communication load
of the LOYTEC devices. For the LOYTEC devices it makes no difference whether
a graphical view is displayed only on one PC or on multiple PCs. The server
fetches the data only once from the LOYTEC devices and distributes it to multiple
graphical views (see Figure 63).

 Graphical view in LOYTEC device: These views are located in the Graphical
Views folder below a LOYTEC device (see Figure 62). In order to display real-
time data, the graphical view communicates directly with the LOYTEC devices
using OPC XML-DA. This approach has the advantage that it offers faster
response times. However, value changes cannot be logged by the server, because
the communication bypasses the LWEB-900 Server.

The alarm view displays the currently pending alarms. It can be opened by clicking on the
alarm icon in the LWEB-900 status bar or by selecting Show Alarms from the context
menu of a folder. An example is shown in Figure 73.

Figure 73: Alarm View

Alarm path

LWEB-900 receives alarms from a number of different sources which are called alarm
servers. Each LOYTEC device can have one or multiple alarm servers. System alarms
originate from the LWEB-900 alarm server in the folder System/Alarming (see Section
6.13.2). The alarm view displays only alarms from alarm servers which are inside the path
set in the breadcrumb navigation bar. To see all alarms, select the top folder. To see alarms
of a single device only, select the corresponding device folder. To see system alarms only,
select the System folder.

Alarm filter

The alarm filter lets you drill down to the specific alarms you want to see. The alarm view
offers a number of predefined filters described in Table 9 or you can use the powerful
custom filter.

Save alarm view

If you regularly need to filter for certain alarms, it might be useful to save your alarm view.
A new alarm view with the current path and filter settings is created in your home directory.
The next time you want access the alarm view, just double click it, and you will see the most
current alarms matching your path and filter.

Figure 76: Alarm View Icon

6.13.2 System Alarms

LWEB-900 monitors all LOYTEC devices. If a device is not responding, the device icon in
the navigation view turns red and a fault alarm is generated in the LWEB-900 alarm server
which is located in the folder System/Alarming.

Figure 77: LWEB-900 Alarm Server

Configure priority of system alarms

1. Right click on the LWEB-900 Alarm Server and select Properties from the context
menu.

2. Select the priority for system alarms. The highest priority is 0, the lowest priority is
255.

Figure 78: LWEB-900 Alarm Server Properties

6.13.3 Alarm Notification

When an alarm occurs, LWEB-900 can notify one or multiple users via e-mail or log the
alarm in a text file. The target of the notification is called an alarm receiver. Primary alarm
receivers are notified as soon as the alarm occurs. Secondary alarm receivers are notified

Version 1.3 LOYTEC electronics GmbH

LWEB-900 User Manual 75 LOYTEC

only if the alarm is not acknowledged in time. A prerequisite to sending e-mails is the
configuration of the outgoing e-mail server as described in Section 6.17.

Create new alarm notifier

The alarm notifier determines which alarms are notified to which alarm receivers. It also
defines the format of the notification.

1. Right click on a folder in the navigation view and select New  New Alarm Notifier
from the context menu. An alarm notifier can be created in the root folder (the project
node), in the home folder of a user, or in any user defined folder.

2. Enter a name and description for the new alarm notifier.

3. Define notification properties:

 Acknowledge timeout: An alarm is sent to the primary receivers first. If it is not

acknowledged after the acknowledgement timeout, the alarm is sent to the
secondary alarm receivers. To disable the acknowledge timeout, set it to 0.

 Notify alarm state changes: If this checkbox is active, the alarm receivers will be
notified when the state of an alarm changes (e.g. alarm condition cleared, alarm
acknowledged).

4. Define one or more notification templates. In case of an e-mail receiver, the template is
used for the message body. If the alarm is logged to a text file, the template specifies
the format of the log entry. You can easily add any column of the alarm view (see
Table 10) to the template using the context menu.

Figure 79: Alarm Notifier, Properties

5. Switch to the Alarm Servers tab and specify a folder as the Base object. The base
object serves the same function as the path in the alarm view: the alarm notifier applies
only to alarms from alarm servers which are inside the base folder.

Version 1.3 LOYTEC electronics GmbH

LWEB-900 User Manual 76 LOYTEC

6. Enable custom filter: If you enable this checkbox, only alarms will be notified which
pass through the configured filter. This filter has the same functionality as the custom
filter for the alarm view.

7. Switch to the Alarm Receivers tab to define who should be notified of the alarm. The
primary alarm receivers are notified as soon as the alarm occurs. Secondary alarm
receivers are notified only if the alarm is not acknowledged in time. To add an alarm
receiver, click on the corresponding plus icon.

8. Enter a name for the alarm receiver and select the type. The E-Mail Alarm Receiver
sends an e-mail notification to one or multiple e-mail addresses. The File Alarm
Receiver logs the alarm in a text file.

9. Configure the properties of the alarm receiver:

 Alarm Template: This template is used when an alarm occurs.

 Alarm State Changes Template: This template is used when the alarm changes
its state. You have to assign this template only if you have selected the option
Notify alarm state changes.

 Enable: Per default this parameter is set to Always. When you click on this
parameter, you can select an enable data point and specify the enable condition.
Figure 80 shows an example: The e-mail alarm receiver “Main Operator” is
enabled if the datapoint operator_status has the value “main”. If the datapoint
operator_status has the value “backup”, the e-mail alarm receiver “Backup
Operator” is enabled. The file alarm receiver “Log File” is always enabled.

Note Use an LWEB-900 Server scheduler to control the enable data point (see Section 6.14)

 E-Mail addresses: For an e-mail alarm receiver, select the e-mail addresses which
should be notified about the alarm.

Note The list of available e-mail addresses contains all users for which an e-mail address has
been specified (see Section 6.25). If you want to send alarm notification to an e-mail
address which does not belong to an LWEB-900 user, you can add this e-mail address in
the project properties: Select Properties from the context menu of the project node in the
navigation view and switch to the Outgoing mails tab.

 File name: For a file alarm receiver, you have to specify a file name. The file is
stored on the server in the directory <project directory>\AlarmReceiverFiles\

6.13.4 Alarm Log

The alarm view contains a live list of currently active and acknowledge-pending alarms. As
soon as an alarm becomes inactive and has been acknowledged, it disappears from the alarm
view. To store a historical log of alarm transitions, the alarm log in the folder
System/Alarming is utilized. This alarm log records transitions of the LWEB-900 alarm
server and all device alarm servers.

LOYTEC devices can have their independent alarm logs. Those device alarm logs are part
of the device configuration and displayed in the Alarm logs sub folder of the device.

Figure 81: Alarm Log Icon

Version 1.3 LOYTEC electronics GmbH

LWEB-900 User Manual 78 LOYTEC

An alarm log can be viewed by double clicking on the alarm log icon in the navigation or
object list view.

Figure 82: Alarm Log

The contents of the alarm log can be exported as a comma separated value list (CSV
export). The alarm log window can be refreshed by hitting the [F5] function key or pressing
the Refresh value toolbar button. If the log contains a large number of entries, the log is
split into multiple pages and the buttons at the bottom can be used to navigate through the
pages. Alternatively, the Go to date button can be used to jump to a specific date and time.

Note Alarms are a special kind of events. Therefore, you can also use the event view (see Section
6.16.4) to investigate alarm transitions. The event view is often more convenient, because
its filters let you drill down to the specific alarm transitions you want to see.

6.14 Scheduling
Schedulers are objects that schedule values of data points on a timely basis. LWEB-900
distinguishes between two kinds of schedulers:

 Device scheduler: The scheduler is executed on a LOYTEC device. Device

schedulers should be used to schedule data points on the device.

 LWEB-900 Server scheduler: The scheduler is executed by the LWEB-900

Server. LWEB-900 Server scheduler should be used to schedule an LWEB-900
user register. The scheduled user register can in turn be used to trigger a report or
to enable/disable an alarm receiver.

Both scheduler types can be configured using the master schedule configuration view in
LWEB-900.

6.14.1 Device Schedulers

Device schedulers are part of the device’s data point configuration. Therefore, they are
created using the device configuration software. How to create device schedulers is outside
the scope of this document. Refer to the device specific manuals (see Table 5).

6.14.2 LWEB-900 Server Schedulers

LWEB-900 Server schedulers are located in the System/Scheduler folder. Per default a
new LWEB-900 project includes 10 schedulers which schedule LWEB-900 user registers of
type Binary. Those user registers are located in the folder System/User Registers. If
necessary, additional user registers and schedulers can be created.

2. Enter a Name and Description for the register.

3. Select the Type of the register. The following types are available:

 Analog: An analog data point typically represents a scalar value.

 Binary: A binary data point contains a Boolean value. The State text defines
human-readable labels for the two Boolean states. Select one of the existing state
texts from the drop-down list or create a new one by clicking on the plus icon.

 Multistate: A multi-state data point represents a discrete set of states. The State
map defines the possible states and the human-readable labels. Select one of the
existing state maps from the drop-down list or create a new one by clicking on the
plus icon.

4. Select the Default value.

5. If you want to use the register in a Parameter view, select the Parameter checkbox.

6.14.3 Master Scheduler View

LWEB-900 offers the unique possibility of organizing schedules in a hierarchical way,
independently of whether they are executed. The resulting tree structure permits defining
entries which apply to all schedulers or only a subset. For example, a standard occupancy
schedule can be defined for a whole building. This global schedule can be modified for
certain areas of the building. The area specific entries can in turn be supplemented by room
specific entries (see Figure 86).

The left side of the day view shows a preview similar to the week view. The right part shows the
details of all defined events. Lower priority events are displayed to the left and higher priority
events are displayed further to the right and partly cover the lower priority events (see Figure
90).

Events with higher priority override events with lower priority. There are three priority
levels:

 Low

 Normal

 Override

If two events have the same priority, the event on the lower hierarchy level overrides the
event on the higher hierarchy level.

Figure 91: Master Schedule Event List

Calendar

Events can reference a calendar pattern which defines on which days the event will be
active. Each calendar pattern is a collection of date entries (see Figure 92). Calendar
patterns can be defined on any hierarchy level. If you define a calendar patterns at the level
of the master schedule folder, it will apply to all master schedules.

Calendar patterns of the current hierarchy level can be edited. Calendar patterns which are
defined on higher hierarchy levels are greyed out and cannot be edited. To see calendar
pattern defined on lower hierarchy levels, activate the checkbox Show calendar patterns
defined at lower hierarchy levels.

If you select a calendar pattern or a date entry, the corresponding days are highlighted in the
calendar pane on the left.

can be configured:

 Name: Each event is given a name. The name has to be unique.

 Value: Select a preset.

 Priority: If two events are scheduled at the same time, the priority defines which
event takes precedence. The following priority levels are supported:

o Low: Lowest priority

o Normal

o Override: Highest priority

If two events have the same priority, the event defined on the lower hierarchy level
takes precedence.

 Start, End, Duration: Define start and end time of an event. At the end of an
event, the value is withdrawn. This means that the event with the next highest
priority can take over and set a different value. If there is no lower priority event,

the default preset will be sent out. If no default preset is defined, no value update
will be sent out.

 Event Type: The event type defines on which days an event will be active. The
following event types are supported:

o One-time: The event is active only on one specific date.

o Daily: The event is executed daily, starting at a specific date and ending
on another date or never.

o Weekly: The event is active on a specific weekday (e.g. every Monday).

o Monthly: Monthly events are repeated every month or only every

odd/even month.

o Yearly: Yearly events are repeated every year.

o Calendar: The days on which the event is active is defined by a calendar

pattern.

o Special: The special event type is available for compatibility reasons.

7. To add additional date entries to the same calendar pattern, repeat Step 5 and 6.

Note Calendar patterns can be defined on any hierarchy level. A calendar pattern will be visible
only at the hierarchy level it was defined and in lower hierarchy levels.

It is possible to add date entries on different hierarchy levels. Date entries are visible only
in the hierarchy on which they were defined and below. In this way, a calendar pattern can
be composed of different date entries in different hierarchy levels.

Download master schedules

After you have configured the schedules in LWEB-900, you have to download them to the
LOYTEC devices. The schedules are executed decentralized in the devices to increases
reliability of the system.

1. The download to the LOYTEC devices is triggered by pressing one of the buttons
shown in Table 13.

Button Description

Download schedulers in or below the currently selected hierarchy level.

Download all schedulers.

Table 13: Schedule Download Buttons

2. The download dialog is shown in Figure 97. If the checkbox Process only modified
items is selected, only the schedulers which have been modified since the last

Version 1.3 LOYTEC electronics GmbH

LWEB-900 User Manual 89 LOYTEC

download will be downloaded. This is useful to speed up the download if you have a
large number of schedulers. If this checkbox is not active, all schedulers displayed in
the list below will be downloaded. This is useful to override any potential changes of
the schedulers on the devices.

Figure 97: Master Schedule Download

3. Press the Start download button.

4. The status of the last download is displayed in the top right corner of the master schedule
view. Clicking on the icon opens the download dialog showing detailed information of the
last download process. After a successful download the following icon is displayed.

Figure 98: Download Status

Note Events which are in the past and unused calendar patterns will not be downloaded to the
LOYTEC device to save resources.

Upload schedules from device

After a schedule has been downloaded by LWEB-900 to a LOYTEC device, it can be

changed locally on the device (e.g. using the Web UI). LWEB-900 detects these changes
and marks changed schedulers with an asterisk. Changes are detected because LWEB-900
periodically polls the devices. The poll cycle is configured as part of the communication
profile (see Section 6.22).

LWEB-900 can upload local schedule changes only if they do not affect other schedulers.
This means that e.g. a change to the start or end time of an event, which was defined on the
scheduler level, can be uploaded. However, if an event is changed, which is defined on a
higher hierarchy level, it will not be uploaded because it might affect other schedulers.

1. The upload of schedules is trigged by pressing one of the buttons shown in Table 14.

Version 1.3 LOYTEC electronics GmbH

LWEB-900 User Manual 90 LOYTEC

Button Description

Upload schedulers in or below the currently selected hierarchy level.

Upload all schedulers.
Table 14: Schedule Upload Buttons

2. The upload dialog is shown in Figure 99. If the checkbox Process only modified items
is selected, only the schedulers which have been detected as modified will be uploaded.
This option is useful to speed up the process if you have a large number of schedulers.
However, if schedulers have been changed since the last poll cycle of LWEB-900,
these changes will not be taken into account. If the checkbox is not active, all
schedulers displayed in the list below will be uploaded. Use this option to get the most
current scheduler configuration from the devices.

Figure 99: Master Schedule Upload

3. If the changes cannot be uploaded into the master schedule configuration, an error will
be displayed as shown in Figure 100. In this example the preset values were changed
using the Web UI. Because the presets affect all other schedulers under the same master
schedule node, the modified presets will not be uploaded to the master schedule
configuration.

Figure 100: Master Schedule Upload Error

4. To find out more about why the upload did not work, double click on the scheduler in
the upload dialog. The pop-up window shows on the left side the scheduler as
configured in LWEB-900 and on the right side the changes made on the device (see
Figure 101).

6.14.3.2 Configure Master Schedule View

Create new master schedule

1. Right click on the master schedule folder and select New  New Master Schedule
from the context menu. If no master schedule folder exists yet, right click on the project
node instead. The master schedule folder is created automatically when creating the
first master schedule.

2. Enter a name and description for the new master schedule and click on OK.

3. The new master schedule is displayed in the navigation view. Double click the master
schedule to open the master schedule view.

Configure scheduler hierarchy

1. To add a hierarchy level select New hierarchical folder from the context menu. Each
hierarchy level can contain further hierarchy levels. Up to three nested hierarchy levels
can be created under the master schedule node. All events defined on a specific
hierarchy level affect all schedulers attached to the same or lower hierarchy levels.

2. To add schedulers to a hierarchy level select Add scheduler… from the context menu.
Device schedulers as well as LWEB-900 Server schedulers can be added. All
schedulers which are added under a master schedule node must be compatible. This
means that the number and type of the scheduled data points must be identical.

Version 1.3 LOYTEC electronics GmbH

LWEB-900 User Manual 92 LOYTEC

Figure 102: Add Scheduler

Note LWEB-900 takes over the presets from the first scheduler which is added to a master
schedule node. Presets can be edited any time.

Scheduler and calendar limitations

Each LOYTEC device has only a limited amount of resources. LWEB-900 knows about
these limitations and checks every time a preset, event, or calendar pattern is added whether
there are enough resources available. Figure 103 shows an example error message which is
caused by adding too many presets.

Figure 103 Too Many Presets Defined

For CEA-709 devices, the number of available daily schedule, calendar patterns, etc. can be
configured in the configuration software. Open the menu Settings  Project Settings …
and select the CEA709 AST tab as shown in Figure 104.

Version 1.3 LOYTEC electronics GmbH

LWEB-900 User Manual 93 LOYTEC

Figure 104: Project Settings, CEA709 AST Tab

For the master schedule view, the following settings are relevant:

 Number of calendar patterns: Influences the number of calendar patterns which

can be created in a master schedule. However, there is no one-to-one mapping of
calendar patterns in a master schedule and in a device. Depending on the
configuration, LWEB-900 sometimes has to split a calendar pattern into multiple
calendar patterns before downloading it into the device.

 Total number of date entries: This parameter specifies the total number of date
entries for all calendar patterns on a device.

 Number of daily schedules: Defines how many events can be created.

 Entries in Time/Value table: Also limits the maximum number of events. Each
event consists of 2 time/value pairs.

 Number of value templates: Defines the maximum number of presets.

Note: Every change of the CEA709 AST settings changes the static network interface of the
device.

6.15 Trending
Trending refers to the ability to log values of data points over time. LWEB-900
distinguishes between two kinds of trend logs:

 Device trend log: The data points are logged by a LOYTEC device. The
LWEB-900 Server reads out the stored data periodically (e.g. once a day). This

Version 1.3 LOYTEC electronics GmbH

LWEB-900 User Manual 94 LOYTEC

approach has the advantage, that data points are logged even if the LWEB-900
server is offline. Moreover, the traffic between LWEB-900 server and LOYTEC
devices is kept to a minimum.

 LWEB-900 Server trend log: The data points are logged directly by the
LWEB-900 server. This approach has the advantage that you do not need to
change the configuration of the LOYTEC device. However, the LWEB-900 Server
has to access the device much more frequently. Therefore, the LWEB-900 Server
trend log is recommended only for temporary trends.

Trend logs can be visualized using a chart view. One chart view can reference multiple
trend logs.

6.15.1 Trend Log Size Limitation

Even on a server with a large hard drive, the disk space is limited. Therefore, you need to
configure for how long the LWEB-900 Server keeps old trend log records.

Configure default values for log size limitations

1. Select Properties from the context menu of the project node in the navigation view and
switch to the Database Log Limitations tab.

2. The trend and alarm log size is limited by the following parameters (see Figure 105):

 Size limit: Trend and alarm logs are organized as ring buffers. As soon as the
maximum number of log items has been reached, new log entries will overwrite the
oldest entries.

 Duration limit: This parameter defines the maximum time span for which old data
is kept before deleting it from the database.

Figure 105: Database Log Limitations

Version 1.3 LOYTEC electronics GmbH

LWEB-900 User Manual 95 LOYTEC

New trend logs are assigned the configured default values. These initial values can be
changed any time by editing the properties of an individual trend log.

6.15.2 Device Trend Logs

Device trend logs are part of the device’s data point configuration. Therefore, they are
created using the device configuration software. How to create device trend logs is outside
the scope of this document. Refer to the device specific manuals (see Table 5).

LWEB-900 automatically detects new records in trend logs of LOYTEC devices. Before the
trend log buffer on the device can overrun, LWEB-900 reads out the trend log data and
stores it in the LWEB-900 database on the PC. The trend log poll cycle is configured as part
of the communication profile (see Section 6.22). Thus, memory limitations on the devices
can be overcome.

All trend logs of a device are stored in the folder Trend logs below the device (see Figure
106). Double click on the trend log to open it.

Figure 106: Device Trend Log

Edit device trend log properties

1. Right-click on a device trend log and select Properties from the context menu.

2. The properties dialog is opened (see Figure 107). You can only modify the Database
Log Limits (refer to Section 6.15.1) parameters. The other parameters are defined by
the device configuration and cannot be edited.

Figure 107: Device Trend Log Properties

Inactive trend logs

The LWEB-900 Server polls the device trend logs periodically. If LWEB-900 detects that a
trend log no longer exist on the device, this trend log is marked as inactive (see Figure 108).
Inactive trend logs are not removed automatically, to ensure that no data is lost by mistake.
To remove the inactive trend log, right click on it and select Delete, or right click on the on
the device and select Upload Device Configuration.

Figure 108: Inactive Trend Log

6.15.3 LWEB-900 Server Trend Logs

Server trend logs can record one or multiple data points and operate in one of the following
modes:

 Interval Mode: In this mode a snapshot of all trended data points is logged
periodically.

 COV Mode: In this mode, each of the trended data points is logged separately if
and only if its value changes. For analog data points, a specific COV increment can
be configured.

Version 1.3 LOYTEC electronics GmbH

LWEB-900 User Manual 97 LOYTEC

 Trigger Mode: In this mode a snapshot of all trended data points is logged each
time a trigger condition fires. The trigger condition is applied to a trigger data
point.

Create a new server trend log

1. Right click on the folder System/Trending in the navigation view and select New 
New Trend Log from the context menu.

2. Enter a name and description for the new trend log.

3. Select the desired Trend mode.

4. If necessary, change the Log size and Log duration parameters (refer to Section
6.15.1).

5. For trend logs of type Interval, select the Log interval.

6. Select Starting date and time. For trend logs of type Interval, LWEB-900 aligns the
log interval to this time.

7. The trending can be enabled/disabled by attaching an enable data point. This data point
should be of type binary. If the value of that enable data point is TRUE, the trend logs
data as defined by the trend mode. If the value of the enable is FALSE, trending is
disabled. If no enable data point is configured, the trend log is always enabled. Click
the … button to select a data point.

8. To remove the enable data point, click the Remove button.

9. Click OK to store the basic configuration of the trend. The new trend log appears in the

Define report data

Figure 126 shows the Datalogs tab of the report properties dialog. This dialog allows you to
configure the data source for your report. Depending on the report template, you can have
one or multiple data groups. The template “Stacked Column Chart“, for example, has the
following two data groups:

Version 1.3 LOYTEC electronics GmbH

LWEB-900 User Manual 113 LOYTEC

 Group 1: All trend logs in group 1 are displayed on the primary y-axis as stacked
column chart. Typically trend logs which represent energy meters are added to
group 1.

 Group 2: All trend logs in group 2 are displayed on the secondary y-axis as line
chart. Group 2 can be used to display data which influences the energy
consumption reported by group 1 (e.g. outside temperature, solar irradiation).

Figure 126: Report Properties, Datalogs Tab

For each data group the following information needs to be configured:

1. Define the time period: All data records with a timestamp inside the time period will be
selected for the report. You have to specify a start date (From) and an end date (To).
Both can be absolute or relative:

 Absolute: An absolute date and time is independent of the time when the report is
generated.
Example: 1.1.2014 at 12:00 AM

 Relative: If you want to create a periodic report or a triggered report, the time
period should be relative to the time when the report is generated.
Example: Relative to start of current month, 1 month ago at 12:00 AM

If the report template has multiple data groups, you can link the time periods of the
different groups by using the Identical to option. For example, after you have defined
the time period for group 1, you can select Identical to Group 1 for the time period of
group 2.

Version 1.3 LOYTEC electronics GmbH

LWEB-900 User Manual 114 LOYTEC

2. Define step interval: The step interval defines the resolution of the report. All data
during the step interval will be aggregated. The aggregation algorithm can be
configured for each data point separately (see Table 20).
Example: To report the daily energy consumption, set the step interval to 1 day and the
aggregation mode to “Delta”.

3. Click on Add… to attach a trend log to the chart view. A trend log selector window is
opened.

4. Select the trend log and click OK. The trend log and the logged data point(s) appear in
the list below the add button.

5. Trend logs can be removed from the chart view by clicking Remove.

6. For each logged data point the following parameters can be configured:

 Report legend: Name displayed in the report. If you leave this field empty, the
data point name will be displayed per default.

 Aggregation Mode: The aggregation mode defines how a value for the step
interval is calculated (see Table 20).

 Scale Factor: Each calculated value is multiplied with the scale factor.
Example: To convert Wh to kWh, enter a scale factor of 0.001.

Aggregation Mode Description

Average Average value during the step interval

First value First value in the step interval
Last value Last value in the step interval
Min value Minimum value in the step interval
Max value Maximum value in the step interval
Sum Sum of all values in the step interval
Delta Calculate the difference between the last value of the current step
interval and the last value of the previous step interval. This
aggregation mode is used for energy counters. To take a
wraparound of the energy counter into account, specify the
parameter Max counter value
On counter Counts how often the value changed from zero to non-zero during
the step interval.
Off counter Counts how often the value changed from non-zero to zero during
the step interval.
Pulse counter Count how many occurrences of the following sequence is
detected during the step interval: change from zero, to non-zero
and then change back to zero.
Running time Time during which the value is non-zero
Down time Time during which the value is zero
Availability RunningTime/(RunningTime+DownTime) in percent

Templates folder. Standard report templates are provided by LOYEC.

Figure 129: Built-In Report Templates

The following sections describe the standard report templates provided by LOYTEC.

Stacked Column Chart

The stacked column chart template contains two data groups. If the second data group is
used, the time period and the step interval for group 2 should be set identical to group 1.

The stacked column chart contains the following report items:

 Header: The report header displays the report name, description, the time period
for group 1, the date and time when the report was created, and the page number.

 Chart: All trend logs in group 1 are displayed on the primary y-axis as stacked
column chart. All trend logs in group 2 are displayed on the secondary y-axis as
line chart.

Figure 130: Stacked Column Chart, Chart

 Step table: The step table contains the same information as the line chart in tabular
form. Each row contains the aggregated data for the corresponding step interval.
The minimum and maximum values are highlighted in bold.

 Statistics table: The statistics table provides a summary of the report data.

 Duration limit: This parameter defines the maximum time span for which old data
is kept before deleting it from the database.

6.19 Global Connections

Global connections are an easy way to connect data points from different LOYTEC devices.
The data is transferred over an IP-based network. Global connections are especially useful
to distribute certain global data (e.g. weather station data, wind alarms, global on/off) in a
system.

To configure such communication, all devices need to be member of a CEA-852 channel.

The configuration of the CEA-852 channel is done by adding devices to a configuration
server using the web UI. Refer to device specific manuals for more details.

3. Define timing parameters for the global connection:

 Max Send Time: This timing parameter of the global connection specifies a
time in seconds, in which a value update is transmitted into the connection,
even if the value has notchanged. This is typically used for heartbeat
functions.

 Min Send Time: This timing parameter of the global connection specifies a
time in seconds, for which transmissions will be delayed after sending out a
value into the connection. This setting can be used to limit the transmission
rate to the connection.

6.20.2.1 Upgrade Device Firmware

Firmware updates can be done either in the Overview tab or in the Firmware file tab.

Upgrading the device firmware is done in two steps: First a new firmware has to be assigned
to the devices. Different device types require different firmware files. This means that you
need to assign a different firmware file to e.g. an LVIS-3E100 device or a LINX-100
device. In a second step the firmware is downloaded to the devices. This can be done in
parallel for all devices independent of the device type.

Assign new device firmware

1. In the device list, select one or more devices which you want to upgrade. All selected
devices have to belong to the same product family. To select all devices of a product
family, right click on a device and choose Select devices with compatible firmware
from the context menu.

2. Click on the Select new firmware file button in the property view.

Note: An alternative method is to choose Select firmware file from the context menu in the list
view.

3. The Select Firmware dialog opens as shown in Figure 148. The dialog displays a list
of compatible firmware files available in the LWEB-900 database. If the desired
firmware version is already available in the list, select it and press OK. You can either
import a new firmware file from the hard disk or check if a new firmware is available
on the LOYTEC web site:

 Hard disk: If you have the firmware file available on your hard disk, click on the
Import new file… button, which opens a file selection dialog.

 LOYTEC web-site: You can download the newest released firmware directly
from the LOYTEC web-site by clicking on the Check for new version on
LOYTEC web-site… button. If a new firmware version is available, LWEB-900
downloads it from the web-site and displays the Readme file.

6.20.3 Device Configuration

A special tab is available to manage the configuration of LOYTEC devices as shown in
Figure 152. The configuration of a LOYTEC device is defined by the following two files:

 Configuration file: The configuration file defines the data points on the device
(e.g. user registers, CEA-709 network variables, BACnet server objects and client
mappings, M-Bus registers, Modbus registers, etc.). The configuration file is
created by the configuration software of the device.

 Parameter file: In the configuration file some data points are marked as
parameters. The parameter file defines the values of these parameters. Not all
LOYTEC devices have a parameter file.

cycle.

 Delayed response: Delayed response is a more efficient alternative to polling. In

this mode, a LOYTEC device delays the poll response until one of the requested
data points has changed. The parameter Hold time specifies the minimum time the
LOYTEC holds off until it responds. Set this value based on the maximum update
rate needed. The parameter Wait time instructs the LOYTEC device to wait the
specified duration after the hold time is reached before responding even if no data
points have changed.

4. Define status polling properties: The LWEB-900 Server monitors all LOYTEC devices
to detect if a device is not responding or if the configuration has changed. The Polling
status properties define how often the device is checked.

5. Define trend and alarm log polling properties: These settings specify how often device
trend and alarm logs are read from the device. This poll cycle has to be configured so
that LWEB-900 reads out the data before the device runs out of memory and overwrites
old data. Usually the devices have enough memory to store log data for several days.
Therefore, it is sufficient to read out log data once a day.

Note: Using the Starting date and time parameter, you can define at what times a poll cycle is
started.

6.24 Offline Mode

The LWEB-900 Server can be set into offline mode. In this mode there is no
communication with the LOYTEC devices. Therefore, no current data point values can be
displayed in graphical view, watch view, and object list view. No alarms are displayed in
the alarm view. The trend chart view, trend log view, and alarm log view display only data
which has already been stored in the database before switching to offline mode.

In offline mode all functionalities which require communication with the device are
disabled (upload/download device configuration and parameters, refresh data point values,
device backup, firmware update, etc.).

Switch to offline mode

1. Press on the Set Project Offline toolbar button.

2. The LWEB-900 client status bar indicates the project is now in offline mode.

Figure 177: Edit Personal Information

6.26 Access Rights

The global access level specified for each user defines the default access rights. These
default access rights can be further refined by defining access rights to the individual
objects in the navigation tree. The effective access rights can never exceed the user access
level.

LWEB-900 uses access control lists (ACL) to define which operations a user can perform
on a certain object (e.g. folders, data points, visualization view, parameter view, trend
charts). Figure 178 shows the default access control list for objects outside the user’s home
directory.

Figure 178: Default Access Control List

The access control contains only a single entry: Allow full control to everyone. This ACL
entry is inherited from the parent object. Because full control is the highest access level, the
effective access level for a specific user is determined by the access level settings in the user
management dialog.

Change access right of an object

1. Right-click on an object (e.g. folder) in the navigation or object list view and select
Access rights from the context menu.

Version 1.3 LOYTEC electronics GmbH

LWEB-900 User Manual 163 LOYTEC

Figure 179: Edit Access Rights

2. Per default an object inherits the access rights from its parent. To remove the inherited
permissions, clear the checkbox Inherit permissions from parent.

3. To add a new ACL entry, click on the button New permission entry. Because the
permission entry is created specifically for this object, this type of entry is called an
explicit permission entry.

Figure 180: New Permission Entry

4. Select the Group/User for which the permission entry applies. Everyone is a special
group which contains all users.

5. Specify the Access Level (see Table 43). Deny permissions take precedence over allow
permissions.

6. To remove an ACL entry, select it and click Delete. Inherited permission entries cannot
be deleted. Disable the Inherit permissions from parent checkbox instead.

7. To edit an ACL entry, select it and click Edit. Inherited permission entries cannot be
edited.

8. If you want to apply the access level settings to all child objects, click on the button
Replace all child explicit permissions by inherited permissions.

Version 1.3 LOYTEC electronics GmbH

LWEB-900 User Manual 164 LOYTEC

Access Level Description

Allow Read The user is allowed to see the value of the object (e.g. data point
value, parameter value).
Allow Write In addition to the permissions granted by Allow Read, the user is
allowed to change the value of the object (e.g. data point value,
parameter value).
Allow Configure In addition to the permissions granted by Allow Read, the user is
allowed to change the configuration of the object (e.g. change
graphical view, add object in folder).
Allow Full Control In addition to the permissions granted by Allow Configure, the
user is allowed to edit the access rights of the object.
Deny Full Control The user is denied to change the access rights of the object.
Deny Configure In addition to the permissions denied by Deny Full Control, the
user is denied to change the configuration of the object (e.g.
change graphical view, add object in folder).
Deny Write In addition to the permissions denied by Deny Configure, the
user is denied to change the value of the object (e.g. data point
value, parameter value).
Deny Read In addition to the permissions denied by Deny Write, the user is
denied to see the value of the object (e.g. data point value,
parameter value).
Table 43: Access Levels

Algorithm to determine effective access rights

LWEB-900 uses the following algorithm to determine if a user is allowed to perform a

certain action on an object:

1. If the action is not allowed due to the access level set in the user management dialog
(see Section 6.25), the algorithm stops and the action is denied.

2. If the ACL of the object contains an explicit Deny entry for the requested action, the
algorithm stops and the action is denied.

3. If the ACL of the object contains an explicit Allow entry for the requested action, the
algorithm stops and the action is allowed.

4. If the ACL of the object contains a Deny entry inherited from the parent object, the
algorithm stops and the action is denied.

5. If the ACL of the object contains an Allow entry inherited from the parent object, the
algorithm stops and the action is allowed.

6. Step 4 and 5 are repeated for entries inherited from the next higher hierarchy level until
the top level is reached.

7. If the evaluation has made it to the top of the tree and the action does not have an
Allow or Deny permission, the action is denied.

Note: It is possible to deny a user read access to a folder but allow him access to lower-down
objects. For example, you can setup the access rights to allow Write access to the folder
Network/Devices, but deny access to the folder Network. In this case, the user cannot use
the navigation and object list view to browse the data points on the devices. However, the
user can use a graphical view to modify the referenced data points.

8 Interfaces

8.1 Trend Log CSV File

The CSV file format for a trend log is defined in this section. The CSV file starts with a
header, containing at least the first line, which specifies the CSV format (log_csv_ver). The
current version is 2. The next line contains the field log_device. It has trailing fields that
specify the vendor, product code, firmware version and device ID string. The Device ID
String contains the host name of the LWEB-900 Server.

The log_info line specifies the ID and name of the trend log object. The line log_create has
two fields specifying the date and time when this CSV log was generated. The line
log_capacity has two fields: the current number of log entries in the file and the log
capacity.

Following are one or more lines of log_item. Each line specifies a trended data point. The
first field is the index, the second the ID of the logged data point, the third the data point
name. The data point name can be augmented by engineering units in square brackets. Log
entries in the CSV refer to the item index to identify the data point, for which the entry was
logged.
#log_csv_ver,2
#log_device;LOYTEC;Product Code;Firmware Version;Device ID String
#log_info;Log-ID;Log Name
#log_create;YYY-MM-DD;HH:MM:SS
#log_capacity;filled;capacity
#log_item;index;UID;data point name [units]

After those lines any number of comment lines starting with a hash character ‘#’ are
allowed. One line contains the column headings. Lines that are not comments specify one
log record per line, using the column information as described below. The columns are
separated by commas ‘,’ or semi-colons ‘;’. If commas are used as a separator, the decimal
point must be a point ‘.’. If semi-colons are used, the decimal point must be a comma ‘,’.

Version 1.3 LOYTEC electronics GmbH

LWEB-900 User Manual 171 LOYTEC

Column Field Example Description

A Sequence Number 50 The log record sequence number. This is the

monotonously increasing sequence number, which is
unique for each log record.
B Source 0 Data point source identifier. Indexes into logger_entry
header. For value lines in a multi-column CSV, this
field indexes the first column, which has a value. For the
ERROR record type, the field indexes the data source
that caused the error. For LOGSTATE, TIMECHANGE
records this field is not applicable and set to 255.
C Record Type 2 The record type: LOGSTATE (0), BOOL (1), REAL
(2), ENUM (3), UNSIGNED (4), SIGNED (5), NULL
(7), ERROR (8), TIMECHANGE (9)
D Error/Time 1 This field is valid for records of type ERROR,
Change/Log TIMECHANGE, and LOGSTATUS.
Status
E Date/Time 2007-11-02 15:34:22 The date/time of the log record. This is in the format
YYYY-MM-DD HH:MM:SS.
F Value 0 24,5 Logged value from source 0 or empty
G Value 1 200 Logged value from source 1 or empty
… …
… Value n – 1 5000 Logged value from source n – 1 or empty
Table 44: Columns of the Trend Log CSV File.

There are as many value columns as value sources specified in the header. If at a given
date/time more values are logged, all of them appear in the same line. If at that given time
some sources did not log values, those columns are left empty. The “Source” column in a
multi-value CSV refers to the first data source that supplied a value in a given line.

8.2 Alarm Log CSV File

The historical alarm logs can also be exported as CSV-formatted files. The CSV format of
the alarm log CSV file is identical to the trend log CSV format as described in Section 8.1.

8.3 Identification Key CSV File

Identification keys can be exported and imported via CSV files. Figure 187 shows and
example.

9.2 Bug Reports

When you report a bug, you can speed-up the problem analysis a great deal if you include
the right information. These guidelines explain how to write such reports.

Before you report a bug, make sure your software is up to date. A good bug report includes
the following items:

 Description how to reproduce the problem. This is the most important part of the
bug report. The developer has to be able to reproduce the bug on his or her own
computer. Include screenshots to document the steps to reproduce the problem.

 System Log: The system log can give useful information about what was
happening at the time when the problem occurred.

 Project backup: Sometimes the problem cannot be reproduced without a backup of

your setup. There might be something unusual about your configuration which is
necessary to reproduce the bug.

Save system log to CSV file

1. Start LWEB-900 Server UI

2. Select File  Display System Log from the menu bar.

3. Press on the button Save to CSV file.
