   Lighting/DALI management – NETx LaMPS

To make the management of KNX/DALI gateways easier, the NETx BMS Platform is providing a dedicate module called LaMPS. The main goal of LaMPS is to provide a generic interface to initiate DALI tests independent of the used KNX/DALI gateway vendor.

The Digital Addressable Lighting Interface (DALI) protocol is an application specific technology that is dedicated to lighting systems. Since it is a pure field level protocol without enhanced management features, it is integrated into other building automation technologies. The most important and most commonly used system for this integration purpose is KNX. So-called KNX/DALI gateways are providing interfaces between the DALI devices and the KNX network. In addition, to simply forwarding commands (e.g. on/off, dimming commands, ...) and information (e.g. on/off status, current brightness value), these KNX/DALI gateways provide sophisticated and enhanced functions. One of the most important feature is the testing of the functionality of the DALI devices.

However, the implementation of this function testing within the KNX/DALI gateways highly depends on the manufacturer of the gateway. Each vendor has its own way how function testing services are provided and how the test results are represented. This also concerns the mapping of this information to KNX communication objects. Even worse, most of the time a simple read and write to these KNX communication objects is not sufficient, since a dedicated command sequence is necessary. A typical example is the reading of the fault status of a DALI device. First, the device must be selected by sending the DALI number to a dedicated KNX group address and afterwards the fault status objects must be read. This results in a complexity which is a major problem for system integrators and electrical engineers, who have the task to provide such functionality. To reduce this complexity the NETx BMS Platform provides a generic interface to initiate DALI test no matter which vendor you use.

Vendor-independent representation of DALI gateways and devices

Depending on the manufacturer, the data provided by DALI gateways is vendor-specific. The NETx LaMPS Module provides a generic view as BMS Platform Items which is independent of the vendor.

Generic interface to initiate DALI tests

One of the most important features of DALI gateways is the support for function tests. However, the interface to these tests is again vendor-specific. Using the NETx LaMPS Module, a generic view to initiate and manage DALI tests is provided.

Support for DALI emergency lighting

Testing emergency lights requires special testing procedures. Again the implementation of these emergency tests is vendor-specific. The NETx LaMPS Module provides a uniform which makes the management of DALI emergency tests more easier and less time-consuming.

Monitoring of operating hours, current, voltage and definition of alarm thresholds

In addition to the management of DALI gateways and their devices, the NETx LaMPS Module provides generic functionality for the management of lighting control systems. In addition to the monitoring of operating hours, current and voltage, thresholds and alarms can be defined. Furthermore, it is possible to make a rough estimation of power and energy values if no smart meters are available.

   Automatic shading control – NETx Shutter Control


For the automatic shading of complex buildings, high user comfort and energy efficiency are of utmost importance. To reach these ambiguous goals, NETx Shutter Control was developed. NETx Shutter Control is an extension to the NETx BMS Platform for automatic shading of complex buildings. It controls blinds considering the current season, weather, sun position as well as the position and 3D geometry of the building.

Project specific

NETx Shutter Control is based on a 3D model, which considers your building but also the sun path and the shadow of the surrounding objects. In combination with live data e.g. weather and position of the sun, the blinds are controlled in an optimum way. Being a project-specific solution, NETx Shutter Control always considers your individual needs as well as special operating modes.


The use of ordinary sensors and actuators is not sufficient for sophisticated shading solutions. The resulting shadow of surrounding objects and building parts cannot be recognized by such simple devices. Complex algorithms and control logic need computational resources that cannot be provided by embedded devices. Therefore, it is necessary to use a software at the management level of the building automation system.


NETx Shutter Control is a solution which was developed for large and complex buildings. You can control and visualize thousands of blinds in a central way.

System architecture

The Core Server of the NETx BMS Platform receives sensor values like the current weather situation and the status of the blinds, and sends control commands for changing the blinds and slats. The control functionality for the automatic shading and other features like maintenance mode and manual/automatic control are provided by NETx Shutter Control. NETx Shutter Control consists of an extension module and the management GUI. The extension module is loaded by the Core Server. It is responsible for the overall control functionality. The manager GUI is the management interface of NETx Shutter Control. It is used by the administrator for configuration purposes.


3D Design

Based on construction plans, a 3D model of the building, the blinds and surrounded objects will be created. This 3D model is the basis for the simulation of the shadow of the building and its environment. The simulation is performed for every minute of the whole year.

Automatic control

Based on the simulation and different run time parameters, all blinds are controlled automatically. The control logic can be adapted to the needs of the building owner. In addition to the current weather situation, other parameters like a manual override or special operating and safety modes can be considered.

Considering the weather situation

One or more weather stations determine the current weather situation. You are free to choose any weather station. You might also use sophisticated stations, which measure the current global solar radiation.

Shading groups

The blinds can be controlled individually or per group.

Slat adjustment

In addition of the position of the blinds, also the position of the slats can be controlled automatically. The slat adjustment is controlled according to the elevation and azimuth angle of the sun.

Manual control

Besides the automatic control, you can also control the blinds manually. We can adapt the manual override to your project-specific needs.

Dynamic calculation of the brightness threshold

To include the current weather situation, you can define a brightness threshold and a hysteresis for each shading group. Dynamic adjustment of the threshold according to the elevation angle of the sun can avoid a glaring due to a low position of the sun
