Adapting Network Planning and Device Identification

Overview

When devices are added in the protocol manager, use the Network Manager or Ethernet Services tab to edit the network planning.

Editing the Network Planning

In the Devices tree, double-click the Industrial_Ethernet_Manager node.

If you use a M262 controller, double-click the controller node in the Devices tree > Ethernet Services.

The Network Manager or Ethernet Services tab shows the devices defined on the device network:

Column	Use	Comment
Device Name	Click to open the device settings	Name of the device. A name is given by default. To rename your device, type a name in the Name box. Do not use spaces within the name. Do not use an underscore (“_”) at the end of the name. Give the device a meaningful name to facilitate the organization of your project.
Device Type	-	Device type
IP Address	Modify the IP address	An IP address is shown as invalid if it has already been assigned to another device that uses the same protocol and DHCP address assignment. If the IP address is invalid, the icon is displayed.
MAC Address	Enter the MAC address	Used to retrieve an IP address through BOOTP. Each IP address must be unique for a particular protocol and for DHCP/BOOTP. For example, you can add the same device for both Modbus TCP and Ethernet/IP protocols, but if you use BOOTP or DHCP to obtain an IP address for one of the protocols, you must enter that same IP address for the other protocol as a Fixed IP address.
Device name	Modify the DHCP device name	Used as device name to retrieve an IP address through DHCP, maximum 16 characters. The DHCP device name must be the same as that defined in the device. Each DHCP device name must be unique. The default DHCP device name is normally compatible with the internal rules of the device. For details on DHCP device name internal rules of the device, refer to the documentation of the device. NOTE: If the proposed DHCP device name is not compatible with the device, you may edit it.

The modifications made in this tab are applied in the Modbus TCP settings tab.

IP Addressing Methods

By default, the added devices use DHCP.

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.	By using DHCP, the FDR service is available. To replace a device, you have to: 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.
BOOTP	The BOOTP server uses the MAC Address of the device to send its IP address:	To replace a device, you have to: Install the new device In EcoStruxure Machine Expert, enter the MAC address of the new device Build the application and load it in the controller. 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, you have to: 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.

Description

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.

By using DHCP, the FDR service is available.

To replace a device, you have to:

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.

BOOTP

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

To replace a device, you have to:

Install the new device
In EcoStruxure Machine Expert, enter the MAC address of the new device
Build the application and load it in the controller.
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, you have to:

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.

Reinitialize IP Address Plan

Click Regenerate IP address to reinitialize the IP address plan associated with the Industrial Ethernet port (for example, after a change of IP address on the Industrial Ethernet port).

EcoStruxure Machine Expert reads the IP address configured on the Industrial Ethernet port and assigns the next available IP addresses to the devices. For example, if the IP address configured on the Industrial Ethernet port is 192.168.0.11, the IP addresses attributed to the devices are 192.168.0.12, 192.168.0.13, and so on.

Out of Process Data Exchanges

Out of process data exchanges are often data exchanges between the control network and the device network. For example, you may use a supervision software or a third-party configuration tool to communicate with a target on the device network.

For more operational details, refer to Out of Process Data Exchanges.

If you need an out of process data exchange, set the correct device gateway address parameter.

The gateway address parameter of the network devices must be set to the IP address of the Industrial Ethernet port of the controller.

A configuration tool must be able to communicate with the network devices in order to set their parameters.

If the configuration tool...	Then...
is connected on the control network	update the network device gateway parameter, see below.
is connected on the device network	the gateway parameter is not used.
uses a protocol other than TCP/IP	the gateway parameter is not used.

To configure the gateway parameter in the network device, refer to the documentation of the device.

NOTE: If the DHCP service is used to address the network devices, the gateway parameter is set in the controller network tab.
