Chapter 1 Product Overview
Typical Ethernet
Configurations
The Multifunctional Access Box with CIP Safety can be connected in any of the
following three network topologies: star, linear, or Device Level Ring (DLR).
Star Topology
The star structure consists of a number of modules that are connected to a
central switch. Modules can be added or removed without affecting the rest of
the network.
Figure 10 - Example of Star Topology
ATTENTION: The access box does not currently support time-sensitive
applications that are based on CIP Sync™, including CIP Motion™ applications.
Do not use the access box in DLR topologies where other nodes are using CIP
Sync or CIP Motion. To be used in linear topologies, where other nodes are
using CIP Sync or CIP Motion, the access box must be connected at the end of
the line.
