ControlNet Overview
Publication CNET-UM001C-EN-P - November 2005
Number of Nodes
Each ControlNet network supports up to 99 nodes. Logix5000 controllers
support multiple ControlNet networks, giving you the flexibility to add more
nodes to your ControlNet network, or to boost performance.
Distances
In a ControlNet network, the maximum distance depends on the number of
nodes on a segment; a segment is a section of trunk between 2 terminators.
Use repeaters to add more segments or gain more distance.
Use this figure to determine whether repeaters are required.
Maximum Allowable Segment Length = 1000m (3280ft) - 16.3m (53.4ft) X [Number of Taps - 2]
