*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.
The use of shielded twisted pair cable (STP) is recommended in environments in which the performance against noise is required.
*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 The connectable Ethernet/IP communication are only GT1455-QTBDE and GT1450-QLBDE.
