PCIe-833x Series
EtherCAT Topology
EtherCAT supports virtually all conncetivity topologies, inculding
line, tree, star, and daisy-chain, making pure bus or line topology
with hundreds of nodes possible, with none of the limitations that
normally arise from cascading switches or hubs.
In system connection, the combination of lines with branches or
drop lines is beneficial, since the ports necessary to create
branches are directly integrated in multiple I/O modules, requiring
no additional switches or active infrastructure components.
Additional flexibility is enabled for supported cable types. Inexpen-
sive industrial Ethernet cable can be used between two nodes up
to 100m apart in 100BASE-TX mode. The Power over EtherCAT
option (compatible with IEEE 802.3af) enables connection of
devices such as sensors with a single line. Fiber optics (such as
100BASE-FX) can also be used, for example for a node distance
exceeding 100 m.
Up to 65,535 devices can be connected to EtherCAT, making net-
work expansion is virtually unlimited, while normal Ethernet arbi-
trary changes between physical layers are allowed.
