*1 When connecting STARDOM to MODBUS
For details, refer to the following manual.
*2 When connect a GOT to a PLC, connect to the PCL Ethernet port via a hub.
Use cables, connectors, and hubs that meet the IEEE802.3 10BASE-T/100BASE-TX standards.
*3 When connecting GT2000 to an equipment that meets the 10BASE (-T/2/5) standard, use the switching hub and operate in an
environment where 10Mbps and 100Mbps can be mixed.
*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 Use the straight cable.

PLC Side Setting
Make the communication settings as shown below. For details of the communication settings, refer to the following
manual.
