This section describes the devices used to comprise a network.
Ethernet cable
Use Ethernet cables that meet the following standards.
■CC-Link IE Field Network Basic
Communication speed Specifications
100Mbps Ethernet cable: Category 5 or higher (STP cable
■General-purpose Ethernet
Communication speed Specifications
100Mbps Ethernet cable: Category 5 or higher (STP cable
10Mbps Ethernet cable: Category 3 or higher (STP/UTP cable
*1 Shielded twisted pair cable.
A straight/cross cable can be used.
Depending on the connection environment, communication errors may occur due to high-frequency noise
from devices other than programmable controllers. The following describes precautionary measures to be
taken on the FX5-ENET to avoid the influence of high-frequency noise.
[Wiring]
• When wiring cables, do not bundle them together with or keep them in close proximity to the main circuit
lines or power cables.
• Place cables in a duct.
• Use STP cables in place of UTP cables.
Hub
Use hubs which satisfy all the following conditions. If hubs not satisfying the conditions are used, operation is not guaranteed.
• IEEE802.3 (100BASE-TX) compliant
• The auto MDI/MDI-X function equipped
• The auto-negotiation function equipped
• Switching hub (layer 2 switch)
*1 A repeater hub cannot be used.
For switching hubs that can be used for CC-Link IE Field Network Basic, refer to the following.
