5. MODBUS(R)/TCP CONNECTION

5.1 Connectable Model List

GOT1000 Series products support the master function of MODBUS
Thus, the GOT can be connected with each MODBUS
For applicable MODBUS

*1 Connect the GOT to the MODBUS
Use cables, connectors, and hubs that meet the IEEE802.3 10BASE-T/100BASE-TX standards.
*2 When connecting GT16 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.
*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.
*5 For details, refer to the MODBUS
*6 GT14 models compatible with Ethernet connection are only GT1455-QTBDE, GT1450-QMBDE and GT1450-QLBDE.
