Group Nodes Into Rings

Arrange your nodes into rings, as shown in the following figure.

Figure 7. Ring Topology

1378

Note The allowable distance between each node is equal to the maximum length of a CAT-5 cable (100 m).

The maximum number of nodes per ring is dependent on the amount of cRIO-9805 Ethernet switches needed to aggregate the system. The maximum ring sizes are also based on the total number of nodes in the system. Design your rings within the limits in the following table.

Total Nodes Maximum Nodes
1 through 15 15
16 through 18 9
18 through 42 7
Note The maximum amount of nodes per ring reduces as total nodes in the system increase to account for the allowable amount of network hops in the TSN network. Refer to (Optional) Adjust Ring Sizes for more information.
