Lenze C520 User Manual

7.1 Conguraon via le
A le named "ip.txt" can be used to set the IP address directly. This le must be stored on the
SD card in the root directory. The le can be created and copied on a Windows PC.
The network sengs are evaluated and accepted when the controller is boong. This transfers
the IP sengs to the parameter seng of the controller automacally; these sengs are
persistent. The le is then renamed "ip_old.txt". It is possible to change the IP addressing at
any me if the le is available again as "ip.txt".
The "ip.txt" le must have the following structure:
IP address
Subnet mask
Gateway address
Example:
192.168.101.221
255.255.255.0
192.168.101.1
If the stac IP address is to be reset to DHCP, only the contents of the "ip.txt" le must be set
to "DHCP". This serves to use DCHP for a dynamic address allocaon at next boot.

7.2 Automac conguraon via parameters
In the "as delivered" condion, the IP address is non-adjustable. However, the IP sengs can
also be specied via a DHCP server. The sengs are congured via the following parameters.
40x2451:004
When using DHCP, changing the IP address may also lead to the network name
being changed. 4Device name ^ 25
Therefore, DHCP should only be used if a there is a local name server in the
network and the network name is not used for the gateway funcon.
7.3 Manual conguraon via parameters
The engineering port must be congured when a stac address is to be assigned.
For this purpose, the "DHCP" buon must bet set to the "Disabled" state [0].
The following parameters can be entered in the »PLC Designer«:
•
IP address 40x2451:001
•
Subnet mask 40x2451:002
•
Gateway address 40x2451:003
Make sure to press the "Restart with current values" buon every me you
change the values.
The conguraon is only persistently transferred to the parameter set via the
"Save user data" device command or by creang a boot project. 40x2022:003
