NETx Tunneller
Comfortable connection between third party OPC clients and NETx Server
The NETx Tunneller simplifies the connection of third party OPC clients (e.g. third party visualization) to NETx Server products (NETx BMS Server, NETx KNX OPC Server). NETx Tunneller is locally installed on the PC where the third party OPC client is running. The OPC client establishes a local OPC connection to the NETx Tunneller. It communicates with the NETx BMS Server via our own VNET protocol. As the connection between OPC client and NETx Tunneller is locally, complex Windows Firewall or Windows DCOM configuration are not required. The connection via VNET is done by using a simple TCP/IP connection that is configured easily.


Also available for main/backup solution
The NETx Tunneller also supports a main/backup configuration. Two NETx Servers can be configured optionally – a main and a backup server. If the NETx Tunneller loses the connection to the main server, the connection to the backup server is activated and the linked OPC clients receive data from the backup server. This switch is done automatically and in a transparent way for the OPC clients. Therefore, also third party OPC clients can profit of the reliable NETx main/backup solution.

Simple import of KNX projects from ETS by using NETx BMS App

To import the configuration of a KNX project into a management application, you can use the function "Export OPC" of the ETS. However, it only exports basic information about KNX installations. Thus, we provide the NETx BMS App which enables you to import the whole KNX project from ETS4 or ETS5 with all meta-information into a NETx Server (NETx BMS Server, NETx KNX OPC Server).


Extended export files contain:

  • KNX group addresses
  • KNXnet/IP router and interfaces as well as their IP configuration
  • ETS project structure incl. network topology (areas, lines, devices and communication objects)
  • Building and trade view
  • Export of all KNX data point types (KNX DPTs)

The app recognizes the configured IP addresses of the KNXnet/IP router and interfaces. According to the building topology, the app assignes KNX group addresses to KNXnet/IP routers and interfaces automatically. So time-intensive and error-prone manual allocation of group addresses has not to be done by yourself. The import of your KNX project into a NETx Server is getting even more comfortable using the NETx BMS app.
