Automatic Private IP Addressing
The Ethernet interfaces support the automatic IP assignment according to the Automatic
Private IP Addressing (APIPA) process.
Interface X127 P1 already has IP address 169.254.11.22 in the delivery condition. Further
information on Automatic Private IP Addressing can be found on the Internet, e.g. in
WIKIPEDIA with the keywords "APIPA" or "Zeroconf".
Separate Ethernet interfaces
The Ethernet interfaces are entirely separate and are generally connected to different networks.
The Ethernet interfaces support:
● S7 routing
● No IP routing
SIMOTION D4x5‑2 can therefore be connected to the machine user's internal company
network with one interface and the second interface can be used, for example, by the machine
manufacturer for the purpose of remote maintenance.
The Ethernet connection of the D4x5‑2 can be configured in HW Config. Proceed as follows
to do this:
1. Open your project.
2. Open HW Config. Double-click the Ethernet port (e.g. X127 P1) to open the "Properties
PNxIE ..." dialog box.
3. You can configure the Ethernet connection in the "Options" tab.
Recommendation: Use the default setting "Automatic setting". With Automatic setting, the
baud rate and duplex operating mode are automatically aligned with the connection partner.
The autocrossing functionality is also available so that you can use crossed and uncrossed
cables.
If transmission is to be set manually, not only must the connection (e.g. 10 Mbit/s half
duplex) be set manually but autonegotiation must also be deactivated.
4. Close the "Properties PNxIE ..." dialog box with "OK".
5. Save and compile the modified hardware configuration.
6. Load the new hardware configuration to the SIMOTION D4x5‑2 via PROFIBUS DP /
PROFINET IO / Ethernet.
Shielded twisted pair cables are used for the networking.
● 4‑ and 8‑wire cables can be used for 10/100 Mbit/s
● 8‑wire cables must be used for 1000 Mbit/s
Note
With SIMOTION < V4.3, the settings are made via HW Config by double-clicking the D4x5‑2
module. The "Properties - D4x5 2" dialog box opens. You can configure the Ethernet
connection in the "Extended Ethernet" tab.
