*1
The destination connected with the twisted pair cable varies with the configuration of the applicable Ethernet network system.
Connect to the Ethernet module, hub, transceiver, or other system equipment corresponding to the applicable Ethernet network
system.
Use cables, connectors, and hubs that meet the IEEE802.3 10BASE-T/100BASE-TX standard.
A cross cable is available for connecting the GOT to the Ethernet module.
The use of shielded twisted pair cable (STP) is recommended in environments in which the performance against noise is
required.
*2
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.
• 10BASE-T: Max. 4 nodes for a cascade connection (500m)
• 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.

Select one of the following [Controller Type] in [Ethernet] of GT Designer3.
• Ethernet module (MELSEC iQ-R Series): RJ71EN71
• Ethernet module (Q Series): QJ71E71
• Ethernet module (QnA Series): AJ71QE71
• Ethernet module (A Series): AJ71QE71
For [Ethernet] of GT Designer3, refer to the following.
