Daisy chain limitations
To help ensure the operational integrity of the network and satisfy the conditions
necessary for maintaining performance, the following limitations have been defined:
b
must use only one of them.
b
network.
b
32. With this limit, the time for a round trip of a packet through the daisy chain is
evaluated at less than 5 ms.
The maximum packet latency of a packet passing through any device in a scan chain
is no more than 10 µs.
In a ring topology, devices or components of the network infrastructure are connected
in a loop with no beginning or end. This type of topology enables different levels of
network redundancy to be obtained.
Ethernet Ring
Ethernet rings are usually the backbones of applications requiring high availability. If
a ring topology is required, then switches that support this function must be used.
Deploying Ring topologies with ConneXium
The ConneXium range offers hubs and switches that allow the deployment of single
and coupled “self-healing” rings. See additional information on page 6/45.

Ring topology
Dual-port Ethernet devices support only 10 Mbps and 100 Mbps data rates and
The network operates only as fast as the slowest device that is connected to the
To improve network traffic, the number of devices in a single scan chain is limited to
