*1 Allen-Bradley product manufactured by Rockwell Automation, Inc. For details of the product, contact Rockwell Automation, Inc.
*2 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 standards.
*3 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.
*4 When connecting GT16 of the function version A to an equipment that meets the 10BASE (-T/2/5) standard, use the switching
hub and operate in a 10Mbps/100Mbps mixed environment.
For how to check the function version, refer to the following.
*5 GT14 models compatible with Ethernet connection are only GT1455-QTBDE, GT1450-QMBDE and GT1450-QLBDE.
*6 The connectable EtherNet/IP communication module differs depending on the PLC series.
