Visualisation and KNX are widely discussed topics which still cause friction. On the one hand, electrical engineers are faced with timeconsuming programming work; on the other hand, restricted options limit the creative scope and make the topic of visualisation into a domain for technically minded KNX experts. With the JUNG Facility-Pilot, visualisation can now be realised for every electrical installer. And the system can do much more.
With the modular JUNG Facility-Pilot software system, a total solution for building management technology has been developed which opens up the topic of visualisation to a broad spectrum of users and moreover contains pioneering developmental steps as regards additional functionality such as access via the Internet. This also fits in with the complete philosophy of the system which makes it possible to set up displays for process characteristics or archives for value characteristics and events without programming. And for specialists, there is also the possibility of visualisation programming. The complete programming environment for BASIC scripts is a prerequisite for this.
Visualisation Editor
The Visualisation Editor provides visually attractive and clear process images which run in the player. Process images are worksheets on which process parameters are represented and various applications can be inserted with the help of stored display elements. Temperatures can also be displayed on a virtual thermometer. The background of the visualisation can be created with DXF, JPG, BMP, WMF or EMF formats.
The basis for the system is the process model which can contain data from different process connections. It can also be taken directly from the EIB Editor. The data of various processes can be linked together without any problems. Functions are created and configured in the process model which work on the basis of parameter values of linked processes and whose results can be sent to the process.
Logic functions
The available logic functions in the process model are amongst others AND, and OR. In addition to the basic functions, there is the Sequence function where specific loads are switched on at the press of a button, as defined in the process model. A presence simulation can thus easily be implemented.
The Forwarding function is a very important function if you have two different process connections for example. If you wish to use or display a value from the heating system (OPC) in the KNX installation, you have a source value which is forwarded to a target value (gateway functionality). A bridge is thus created in a simple way between the process connections.
The status variable takes the last reported value and simulates KNX status objects if specific KNX devices for instance do not have these status objects at their disposal. There is also an IF/THEN function which can be used to configure a priority control: The value of a switch will only be sent to an actor, when the control of the actor by the switch is allowed. The allowance may depend on another binary process variable.
The system also incorporates a time delay – for example, when you switch the light on in the toilet the fan is activated with a time delay. No further installation is required and the user has the option of setting times as required without ETS programming.
Another important function is the Counter, for example if you wish to know how often the burner of the heating system cycles, its starting and stopping pulses are taken as the basis. You then count how long the burner is active for. The hours and minutes of the operating time can be displayed with the help of the counter as well as the average switching time.
In addition the Weekly Time Switch can be used to programme time controlled scenes. The user can change these scenes by himself, and can configure when the scenes have to be activated during the week.
EIB Editor
The KNX/EIB process connection is carried out via the EIB Editor. It is used to read the project data from the ETS program. The editor uses the FALCON driver of EIBA. The new KONNEX data types are therefore also supported whose correspondence with the previous EIS types is explained in the help file of the editor.
The option to access the system via PDA or the Internet with web browsers but without knowledge of HTML is already in development. The user administration is created so that the areas to be protected by the Facility-Pilot are secured against unauthorised access. For security purposes, individual components of the system can only be made accessible to predefined user groups.
