13th KNX engineer course: KNX bus topology and address planning in practice

The 13th KNX engineer certification course concluded in January. The first half of the course revisited the bus fundamentals, and the second half spent a full day on group address planning and topology design.

This was a deliberate choice for the cohort. In a KNX project, the topology structure and the group address table are two documents that get cheaper the earlier they are settled: how lines are divided, how device addresses are allocated, which group addresses a scene calls — clarify these three things at drawing stage and the site is built to the table. The other way round, adding panels on the spot and changing logic ad hoc leaves the group address table inconsistent with reality, and every later commissioning run has to be checked again.

Training was grouped by the scale of the area: from line division in a single room, through to address allocation conventions for multi-storey villas and multi-zone commercial buildings, progressing step by step, with particular attention to address reservation — leaving space for devices that may be added later, so already-allocated addresses are not consumed.

All participants passed the closing assessment and received the KNX international certification certificate. The training plan for the new year is scheduled, and engineers and teams interested are welcome to book a place in advance.
