Infrastructure for EtherCAT/Ethernet

Version: 2.1
• The employment of rigid Ethernet cables instead of stranded wires is recommended where possible on
account of the better electrical properties (Attenuation
stranded
> Attenuation
rigid
).
• It is recommended to employ larger core cross-sections if possible, (e.g. AWG22 instead of AWG26)
on account of the better electrical characteristics (Attenuation
thin core
> Attenuation
thick core
). If the length
exceeds 50 meters, too small a cross-section (AWG26) can prevent conformity to the performance
class!
• It is recommended to check the installed Ethernet cabling before commissioning.
• It is recommended to monitor installed Ethernet cabling during operation using a means of software
diagnosis (e.g. Beckhoff TwinCAT).
In accordance with the specified standards, a verification decision on a cable section can thus be made as
follows:
