EtherNet/IP™ networks – Recommendations
The Ethernet Industrial Protocol (EtherNet/IP™) is an open communication standard
based on the conventional Ethernet protocols TCP/IP and UDP/IP.
EtherNet/IP™ has been defined by the

and

nternational (CI).
EtherNet/IP™ extends the Ethernet technology by the CIP application protocol (

it is also used as an application protocol for DeviceNet™ and ControlNet™.
INFORMATION
Adhere to the information and regulations of the ODVA when planning your EtherNet/
IP™ network and taking it into operation.
This chapter describes the most important conditions to be observed for planning and
operating an EtherNet/IP™ network. The list is not complete.
9.1
Network components
Observe the following when selecting the network components for an EtherNet/IP™
network:
•
Use only industry-standard network components.
•
Use industry-standard switches.
•
Use fast Ethernet according to IEEE802.3u.
•
The managed switch must support VLAN tagging according to IEEE802.1Q.
9.2
Maximum line depth
It is recommended to use a maximum of 50 fieldbus nodes in a line regardless of the
poll rate.
9.3
Network load
The network load should not exceed 80% of the bandwidth at any point in the network.
