IP Addressing Methods

Presentation

This table presents the IP addressing methods:

Method	Description	Details
DHCP	The DHCP server uses the DHCP device name of the device to send it its IP address: The DHCP device name is also used by the FDR service.	New devices use the DHCP addressing method by default. By using DHCP, the FDR service is available. To replace a device: Install the new device Define the DHCP device name in the device Power up the device and launch the application. At power up, the new device is recognized and the controller loads the previously stored configuration into the new device.

Configure the parameters in the device. Power up the device and launch the application.
Fixed	The IP address is fixed in the application.	To replace a device: Install the new device Configure in the device the network settings (IP address, subnet mask, and gateway address). Configure the parameters in the device directly or using EcoStruxure Machine Expert. Power up the device and launch the application.

DHCP

The DHCP server uses the DHCP device name of the device to send it its IP address:

The DHCP device name is also used by the FDR service.

New devices use the DHCP addressing method by default.

By using DHCP, the FDR service is available.

To replace a device:

At power up, the new device is recognized and the controller loads the previously stored configuration into the new device.

BOOTP

The BOOTP server uses the MAC Address of the device to send its IP address:

To replace a device:

Fixed

The IP address is fixed in the application.

To replace a device:

Install the new device
Configure in the device the network settings (IP address, subnet mask, and gateway address).
Configure the parameters in the device directly or using EcoStruxure Machine Expert.
Power up the device and launch the application.

When using the DHCP addressing method, the DHCP server assigns IP addresses to devices upon request.

To activate the DHCP server, proceed as follows:

Step	Action
1	In the Devices tree, double-click the Industrial Ethernet port node.
2	Select the DHCP Server active check box. When active, devices added to the fieldbus can be configured to be identified by DHCP device name instead of by MAC address or fixed IP address.

Step

Action

In the Devices tree, double-click the Industrial Ethernet port node.

Select the DHCP Server active check box.

When active, devices added to the fieldbus can be configured to be identified by DHCP device name instead of by MAC address or fixed IP address.
