11.2 System Configuration
Use hubs that satisfy the following conditions.
• Conform to the IEEE802.3 (100BASE-TX) standard.
• Include Auto MDI/MDI-X.
• Include an automatic negotiation function.
• Switching hub (layer 2 switch)

Connect the GOT to the CC-Link IE Field Network Basic master station via a hub.
Use cables, connectors, and hubs that meet the IEEE802.3 100BASE-TX standards.
A length between a hub and a node.
The maximum distance differs depending on the Ethernet device to be used.
The following shows the number of the connectable nodes when a repeater hub is used.
• 100BASE-TX: Max. 2 nodes for a cascade connection (205m)
When switching hubs are used, the cascade connection between the switching hubs has no logical limit for the number of
cascades.
For the limit, contact the switching hub manufacturer.
Use the straight cable.
CC-Link IE Field Network Basic communication does not support connection beyond routers.
GT25-W does not support the option device.
