EtherCAT supports linear, tree or star structures. The bus or linear structure used in
the field buses is thus also available for Ethernet. This is particularly practical for
system wiring, as a combination of line and stubs is possible.
For transmission according to the 100Base-TX Fast Ethernet standard, patch cables
in category STP CAT5 must be used (2 x 2 shielded twisted pair copper wire cables).
The cables are designed for bit rates of up to 100 Mbit/s. The transmission speed is
automatically detected by the measuring system and does not have to be set by
means of a switch.
Addressing by switch is also not necessary; this is done automatically using the
addressing options of the EtherCAT master.
The cable length between two subscribers may be max. 100 m, a total of 65535
subscribers are possible in the EtherCAT network.
In order to ensure safe, fault-free operation,
-
ISO/IEC 11801, EN 50173 (European standard)
-
ISO/IEC 8802-3
-
and other pertinent standards and directives must be complied with!
In particular, the applicable EMC directive and the shielding and grounding directives
must be observed!
