3.2 Installation of bus cable
INFORMATION
• According to IEC 802.3, the maximum cable length for 10/100 MBaud Ethernet
(10BaseT/100BaseT), e.g. between 2 ECC-DFC fieldbus controllers, is 100m.
• VLAN tag-prioritized Ethernet frames with the frame identification 8892
hex
are used
for the real-time data exchange with PROFINET IO. This requires switched net-
works. The switches must support prioritization. Hubs are not permitted. Data
transmission takes place using the full duplex process with 100MBit. Detailed in-
formation on cabling can be found in the "PROFINET Installation Guideline" pub-
lication that was issued by the PROFINET user organization.
3.2.1 Shielding and routing bus cables
NOTICE
Danger of flowing compensating currents due to the incorrect cable type, inadequate
shielding, and/or the incorrect routing of bus cables.
Possible damage to property.
• In the event of fluctuations in the ground potential, a compensating current may
flow via the bilaterally connected shield that is also connected to the protective
earth (PE). Make sure you always supply adequate equipotential bonding in ac-
cordance with the relevant IEC regulations.
Only use shielded cables and connection elements that meet the requirements of cat-
egory 5, class D as per IEC11801 edition 2.0.
You can take the following measures to minimize electrical interference:
• Manually tighten the mounting screws on the connectors, modules, and equipoten-
tial bonding conductors.
