64. MODBUS(R)/TCP CONNECTION
64.1 Connectable Model List
GOT1000 Series products support the master function of MODBUS
®
/TCP communication, the open FA network.
Thus, the GOT can be connected with each MODBUS
®
/TCP slave.
For applicable MODBUS/TCP equipment, refer to the following Technical News, or contact your local distributor.

Connection (GOT-A-0037)
64.2 System Configuration
64.2.1 Connecting to MODBUS/TCP equipment
*1 Connect the GOT to the MODBUS/TCP equipment via a hub.
Use cables, connectors, and hubs that meet the IEEE802.3 10BASE-T/100BASE-TX standards.
*2 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.
*3 Use the straight cable.
The use of shielded twisted pair cable (STP) is recommended in environments in which the performance against noise is required.
*4 For details, refer to the MODBUS
®
/TCP equipment manual.
