7.3 Ethernet
The CPU-board of PPU1740 provides ethernet controllers for three GbE interfaces. The
connectors for the interfaces X130 and X120 are located on the CPU-Board and the interface
X127 is located on the Front-adapter, which is the interface to the backside of the panel.
X130, X120, X127 pin assignment and use
The interfaces are designed for operation in full-duplex mode; in other words, the ports can be
used for the sending as well as for the receiving of data packets. The ports are connected as
an Ethernet terminal with up to 1000 Mbit (1 Gbit):
● X130 is pre-configured as DHCP client and connects the PPU to the company network and
for example remote diagnostics via teleservice adapter IE.
● X120 is pre-configured as DHCP server and provides the link to the system network (e.g.
Ethernet MCP or HT2).
● X127 is used for commissioning. It is preconfigured as DHCP server for a peer-to-peer
connection with permanently set IP address 192.168.215.1 (e.g. for access with Access
MyMachine /P2P via PG/PC).
You can find further details in the following manuals:
● SINUMERIK ONE Base Software and Operating Software Commissioning Manual
● SIMATIC TS Adapter IE Manual.
Note
The following devices are not supported by X120:
● TCU
● ITC
● IPC / PCU.
