This document contains all the information required to use ETS 3 in combination with UniOP All EIB compliant devices come with a device descriptor delivered as a file to be imported in the configuration tool The UniOP descriptor is contained in a file called The file can be imported in ETS 3 and used in the planning phase of the project The model adopted by UniOP HMIs corresponds to an EJB device with no objects Programming the panel is done as usual using the Designer software For what concerns the ETS 3 the only function supported by UniOP is the UniOP physical address assignment tn250 2 doc 9 06 2008 Connecting UniOP to KNX EIB Networks 4 2 Principle of Operation The UniOP implementation of the EIB communication protocol is designed to allow the access to the Group Address blocks defined in the ETS 3 project Depending on the nature of the group address the user will be able to define the type of the access read only or read write Tags in the Designer database correspond to group address in the ETS 3 project A tag import process is defined to transfer database information from ETS 3 to Designer All dynamic objects in a Designer project refer to a Group Address At run time upon showing any page of the project for the first time the HMI panel may generate a sequence of read operations to update the value of the status for all the objects present in that page In case the target device does not reply to UniOP re
3. 2008 Connecting UniOP to KNX EIB Networks 1 Introduction KNX is the association that promotes the KNX communication standard designed to be applied to Home and Building Electronic Systems The KNX standard approved as European Standard EN 50090 EN 13321 1 is based on the communication stack of EIB with some extensions EIB is the acronym for European Installation Bus Additional information and further details can be found on the KNX web site www konnex org The network communication media supported by the UniOP panels is TP 1 twisted pair type 1 which corresponds to a bus line operating at 9600 bit s Connection to KNX systems requires the optional EIB communication module TCM17 Please see the Appendix for a summary of the requirements The EIB is an event driven decentralized automation system The information to be transmitted over the bus is organized in telegrams sent by a source to one or more destination devices The bus line of EIB systems carries both data and power for the devices The data is modulated over the DC voltage of the power supply UniOP HMI panels are not powered from the network and they still need the usual the power supply The planning design and commissioning of EIB KNX installations are normally done using the ETS configuration software This software tool is supplied by the EIBA organization This document refers to the ETSTM 3 version of the software ETS is a registered trademark of EIBA
