14.3 Ethernet Connection
14.3.1 System configuration for connecting to SIMATIC S7-300/400 series
(Ethernet connection type: FETCH/WRITE)
*1 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 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 Product manufactured by Siemens AG. For details of the product, contact Siemens AG.
*4 If the number of GOTs increases, the communication becomes highloaded, and it may affect the communication performance.
