Configuration via file

A file named "ip.txt" can be used to set the IP address directly. This file must be stored on the
SD card in the root directory. The file can be created and copied on a Windows PC.
The network settings are evaluated and accepted when the controller is booting. This transfers
the IP settings to the parameter setting of the controller automatically; these settings are
persistent. The file is then renamed "ip_old.txt". It is possible to change the IP addressing at
any time if the file is available again as "ip.txt".
The "ip.txt" file 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 static IP address is to be reset to DHCP, only the contents of the "ip.txt" file must be set
to "DHCP". This serves to use DCHP for a dynamic address allocation at next boot.

Automatic configuration via parameters

In the "as delivered" condition, the IP address is non-adjustable. However, the IP settings can
also be specified via a DHCP server. The settings are configured via the following parameters.
40x2451:004
When using DHCP, changing the IP address may also lead to the network name
being changed.
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 function.
7.3

Manual configuration via parameters

The engineering port must be configured when a static address is to be assigned.
For this purpose, the "DHCP" button 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" button every time you
change the values.
The configuration is only persistently transferred to the parameter set via the
"Save user data" device command or by creating a boot project.
