Configure Your Link With Repeaters
When you configure your link using repeaters, you can install them in
one of three ways:
A repeater can be connected to a segment at any tap location.
Install Repeaters in Series
When you install repeaters in series, use your ControlNet Network
management Software (RSNetWorx) to verify that the system is an
allowable configuration. The system size is based on the maximum
number of repeaters (5) in a series and length of the media used
between any two nodes.
Refer to the Installation Instructions that shipped with your repeater
for an example series toplogy drawing.
ATTENTION
!
Do not power both repeaters at the same time.
Powering both repeaters at the same time disrupts
communication on the network. Use the fault-relay
contact of the primary repeater to control power to
the backup repeater.
You can install repeaters in: See page:
series 2-8
parallel 2-9
a combination of series and
parallel 2-9
ATTENTION
!
The maximum system size is based on the distance
between any two nodes. The total amount of cable
used in the network is limited only by the distance
between the farthest two nodes.
