I note that recent Velbus documentation says bus layout is pretty flexible and can be star or loop or line or combinations of these but I am wondering if this is really OK regardless of cable length.
I have approx 60 dimmer/relay modules (VMBDMI-R and VMB4RYNO) on my DIN rail. These are a simple line bus over about 20m length (actually as 3 nodes, 10m apart).
I will also have approx 35 switch modules (each is a VMB8PBU) and I would like to connect these to the bus above as a single star (35 separate cable runs) where each cable may be anything from 5m to 30m.
Is this combination of cable lengths and bus topology likely to work OK? Or should I rearrange the switch modules as one long chain? or 3 chains (one attached per node above)?
