Definition
Logical level of the KNX TP topology. In the historical TP-64 model, a segment supports up to 64 devices and a line can have four segments with repeaters. TP-256 allows up to 256 devices on a compatible segment; verify devices, bus load and power supply before applying this limit. Up to 15 secondary lines per area.
