7.7 Use of Ethernet interfaces
Application
The following connections can be established via the Ethernet interfaces:
• X120 provides the link to the system network (e.g. operator panels).
• X130 connects the NCU to the company network.
• X127 is used for commissioning and remote diagnostics via teleservice adapter IE.
You can nd further details in the following manuals:
– SINUMERIK 840D sl Basesoftware and Operating Software Commissioning Manual
– SIMATIC TS Adapter IE Manual
Properties
The interfaces are full duplex 10/100/1000 Mbit Ethernet ports. Both ports are connected as an
Ethernet terminal.
