*1 When connecting STARDOM to MODBUS /TCP, Modbus Communication Portfolio License is required.
For details, refer to the following manual.
*2 When connect a GOT to a PLC, connect to the PLC Ethernet port via a hub.
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 Use the straight cable.
The use of shielded twisted pair cable (STP) is recommended in environments in which the performance against noise is
required.
