Edit Topology Dialog

To access this dialog:
In the EtherCAT Editor, on the toolbar, click the Edit Topology button.
Or, in the EtherCAT Editor, right-click the EtherCAT MainDevice and select Edit Topology.
Or, on the EtherCAT menu, select Edit EtherCAT Topology.

The Edit Topology dialog is one tool available for adding or removing SubDevices in an EtherCAT Network. For complete instructions on adding, removing, and reordering SubDevices in an EtherCAT network, see Editing the EtherCAT Topology.

Note: SubDevices added with this method will have default settings. To duplicate existing SubDevices with their configuration settings, see Editing the EtherCAT Topology.

This dialog is suitable for adding new SubDevices and removing SubDevices. Using this dialog is not the recommended method for re-ordering the SubDevices in the network if you wish to keep the configuration settings of the SubDevices. For re-ordering SubDevices, see Editing the EtherCAT Topology.

Before Using this Dialog

These steps should be completed before using the Edit Topology dialog:

Make sure that the ESI files for the new SubDevices are installed. See EtherCAT SubDevice Information (ESI) File for details.
Remove and reconnect EtherCAT cables as required to add the SubDevice(s). Keep track of which SubDevices are connected to which.
Make sure RMCTools is online with the RMC.

Dialog Components

Configuration box: Displays the configuration as defined in RMCTools.
Scanned Configuration box: Displays the configuration of the physical network, after clicking Scan.
Add, Remove, and Replace Buttons:

Use these to add, remove or replace the SubDevices in the Configuration box.

Using this Dialog

Typically, this dialog is used after making physical changes in the EtherCAT network, and the objective is usually to make the Configuration box match the Scanned Configuration box.

Add devices as follows:

In the Configuration box, click a device next to the location where you want the new device to be located.
In the Scanned Configuration box, click the device to be added.
Click Add SubDevice Above or Add SubDevice Below. If you make a mistake, remove the device as described below, then try again.

Replace devices as follows:

In the Configuration box, click the device to be replaced.
In the Scanned Configuration box, click the device to take its place.
Click Replace SubDevice.
If you make a mistake, you will need to click Cancel and start over.

Remove devices as follows:

In the Configuration box, click the SubDevice to remove.
Click Remove SubDevice.

Note: If removing a SubDevice fails, you may need to first remove all the SubDevices contained by that SubDevice.

Select Apply to apply the changes made in the Configuration box to your network.
