Q01
The KNX standard is internationally standardised under the reference ISO/IEC 14543-3.TrueFalse1. System Overview· Normung· EasyCorrect answerTrueLearning tipKNX is standardised by ISO/IEC 14543-3 (Information technology — Home Electronic System (HES) Architecture). It is also covered at European level by the EN 50090 series and at Chinese level by GB/Z 20965. This multi-level recognition is one reason KNX is positioned as a vendor-neutral open standard.
Q02
The four communication media supported by KNX are TP, IP, RF and PL.TrueFalse1. System Overview· Übertragungsmedien· EasyCorrect answerTrueLearning tipKNX supports four physical media: TP (twisted-pair, the reference bus), IP (Ethernet/Wi-Fi via tunnelling or routing), RF (radio at 868 MHz) and PL (Powerline at 110 kHz over the mains). In practice TP and IP dominate today, while PL110 has seen very limited deployment in new installations since around 2010.
Q03
A standard KNX device that is fully programmed contains an Individual Address, an application, parameters and the Group Addresses.TrueFalse1. System Overview· Offizielle Musterprüfung 3· MediumCorrect answerTrueLearning tipTrue. After a successful complete download from ETS, a standard KNX device stores four things: its Individual Address (unique identifier on the topology), its application program (the firmware-level logic for its function), its parameter values (the configuration choices made in ETS), and the list of Group Addresses linked to its Group Objects (the communication side). Only with all four does the device participate correctly in the installation.
