3. MICROCOMPUTER CONNECTION (ETHERNET)

3.1 Microcomputer connection (Ethernet)
The "microcomputer connection (Ethernet)" is a function by which data can be written or read from a PC, microcomputer
board, PLC, etc. (hereinafter referred to as "host") to virtual devices of the GOT after connecting the host to the GOT with
the Ethernet.
Interrupt output is also available from the GOT to the host.
For the flow of the data processing, such as reading or writing data and interrupt output, refer to the following.

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.
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.
The GOT2000 Series Ethernet communication unit (GT25-J71E71-100) is not applicable.
