8.2.2 Connection to Built-in Ethernet port CPU or C Controller module
*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.
*2 A straight cable is available.
When connecting QnUDE(H) and GOT directly with Ethernet cable, connection by cross cable is available.
*3 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.
GT16 User's Manual (Hardware)
*4 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.
*5 For the system configuration of Built-in Ethernet port QCPU, refer to the following manual.
QCPU User's Manual (Hardware Design, Maintenance and Inspection)
*6 Select [QnUDE(H)] for [Controller Type] in [Ethernet] of GT Designer3.
For [Ethernet] of GT Designer3, refer to the following.
8.3.3 Ethernet setting
*7 For the system configuration of Built-in Ethernet port LCPU, refer to the following manual.
MELSEC-L CPU Module User's Manual (Built-In Ethernet Function)
*8 Select [LCPU] for [Controller Type] in [Ethernet] of GT Designer3.
For [Ethernet] of GT Designer3, refer to the following.
8.3.3 Ethernet setting
*9 GT14 models compatible with Ethernet connection are only GT1455-QTBDE and GT1450-QLBDE.
