Net'n Node Developer - Bus Monitor, Analyser and Test Tool for KNX Bus Systems
Area of Application
The quality of development always depends on the quality of the tools used. When developing KNX/EIB devices, it is essential to examine the behaviour of the device on the bus. To do so, a bus monitor is required to make visible the telegrams exchanged over the bus. Our Net'n Node software is an extremely powerful bus monitor that features a set of highly efficient tools for analysing the bus devices and the system.
Features
- Sending and receiving telegrams over KNX
- Analysis of a KNX installation
- Analysis and control of single devices
- Reading out communcation objects
- Programming bus devices
- Composition of programming sequences
- Access to KNX over serial, USB and IP interfaces
Sending and receiving telegrams
Net'n Node is able to track all telegrams exchanged over the KNX. The telegrams can be filtered according to their layer, and further information such as the service code or time stamp can be displayed.
For the sending of telegrams many predefined templates are available. An individual input is possible as well. The figure shows dialogs for sending telegrams with KNX data point types.
Telegram filters
It is possible to filter telegrams based on the following criteria:
- EMI Service code
- Source Address
- Individual Destination Address
- Group Destination Address
- Application Layer Service (APCI)
- Transport Layer Service (TPDU)
- Network Layer Parameter (Route Count)
Filters can be configured to hide specific telegrams, or mark them with a specified color. Filter configurations can be saved to file for later use.
Analysis of KNX installations
Net'n Node is able to make visible all devices connected in a line or area of an KNX installation. Also, a range of physical or group addresses can be examined to determine whether an acknowledge was returned by a certain address, as shown below.
Analysis and control of KNX devices
Net'n Node provides a large number of tools for the analysis and control of single devices. These functions are:
- Access protection
- Switching of LED
- Reset device
- Read state
- Read A/D-Converter
- Edit memory
- Edit properties
- Manipulate physical address
The figures above show the following functions: the dialog for the reading out and for the modification of interface objects (properties) and the dialog which retrieves the status of a device.
Every device oriented dialog has on the right a Read and a Write button for the individual address of the target device: If the programming mode is activated this feature can read or write the address without exit of the dialog.
Reading out communcation objects
The content of a communication object can be read using its group address. Every meaningful interpretation of the content is listed.
Programming of bus devices
Net'n Node is able to manipulate the structures of the different BCU versions. These structures include the association table, the address table and the communication object table. Also, any features introduced with the BCU2, such as properties, can be handled with Net'n Node. The entire memory of a device can be downloaded and manipulated, and the elements of the tables can be highlighted in colour. The figures to the left show the menu for manipulating a communication object and the tables of a BCU.
The content and order of a loading sequence can be specified in detail. Net'n Node is able to read, edit and export s19 files, which contain the loading sequence for ETS.
Compilation of programming sequences
Similar to the loading sequence described above, other programming sequences can also be created. Thus it is possible, for example, to exchange the manufacturer code of a bus device after production.
