Network Topology

Which network topologies can be realized?
The IEEE1394a technology allows the building of extended networks with up to 63 participants.
With the component ION PROFIBUS DP SPY T001, tree and chain topologies can be built.
Caution
The net topology is equal to the one of a bus with branching - but without loops!
Tree topology
The tree topology facilitates the building of networked systems by connecting two further nodes to each node.
Chain topology
The chain topology enables the building of networked systems by connecting one further node to each node.
Caution
The maximum number of nodes per bus is limited to 63. The maximum number of hops (peer-to-peer-
connections) from one node to any other node is limited to 15 - i.e. there may not be more than 16 nodes con-
nected in a row.
