Network structure
A full Konnex network consists of three structural levels. The uppermost level is the
area line with a maximum of up to 15 main lines (medium level).
Up to a maximum of 15 lines in turn from each main line (lower level).
Theoretically up to a maximum of 253 devices (bus members) may be located on
one line.
For RCB / RXL, we recommend a maximum of 45 devices per line for technical
communication reasons.
The three-level network structure requires area or line couplers.
Without these couplers, the network structure is limited to one single line.
