  An input field for text input appears.

Assign topology name

2. Enter the desired name and confirm the entry with or discard the entry with .

  The topology is renamed.

Edit devices in topology via context menu

Devices already inserted in the topology can be edited via a context menu using the right mouse button or by double-clicking. The following functions can be executed via the context menu:

• Delete devices from topology

• Copy parameter set of one device and paste it into another device

• Clone devices

• Query and display current device status

• UPDATE IODD

Delete devices from topology

  In the topology, right-click the device you want to delete and select DELETE DEVICE.

  The device is deleted from the topology.

Copy and paste parameter set from devices

You can copy the current parameter set of a device and paste it into another device.

To do this, the following requirements must be met:

• Both devices are identical models.

• Both devices have the same IO-Link version.

1. In the topology, right-click the device whose parameter set you want to copy to another device and select COPY PARAMETERS.

  The parameter set is copied to the buffer. 2.
2. in the topology, right-click the device to which you want to paste the copied parameter set and select PASTE PARAMETER.

  The previous parameter set is overwritten with the new parameter set. Both devices now have the same parameterization.

CLONE DEVICE

You can clone devices in the topology. The cloned device has the same parameterization as the device from which it was cloned. The cloned device is not connected to an IO-Link network module and can therefore be connected like a normal device.

  In the topology, right-click the device you want to clone and select CLONE DEVICE.

  An identical device is inserted into the topology.

Query and display current device status

The statuses of the IO-Link devices and network modules of the physical topology are queried and updated cyclically. The states are displayed as follows:

Symbol	Example image	Description
		A different IO-Link device is present at the port of the IO-Link network module than was previously present in the topology.
		The connection to the device is interrupted.
		The IO-Link network module is currently controlled by a memory controller.
WITHOUT		Connection is established

  In the topology, right-click the device whose current device status you want to query and select UPDATE.

  The state of the device is displayed to you.

UPDATE IODD

Für unbekannte (generische) IO-Link-Geräte oder nicht übereinstimmende Geräte ist ein Hinzufügen der entsprechenden Gerätebeschreibungsdatei notwendig. Dazu stehen Ihnen drei Wege zur Verfügung:

1. Via the context menu.

   Update IODD via context menu

     Klicken Sie in der Topologie mit der rechten Maustaste das unbekannt/nicht übereinstimmendes Gerät, dessen Gerätebeschreibungsdatei Sie aktualisieren möchten, und wählen Sie IODD AKTUALISIEREN.

   

     The parameters of the device are updated according to the automatically imported device description file.

2. Über die Funktion IODDs aktualisieren in der Topologie. Beachten sie, dass die Funktion erst sichtbar wird, wenn Sie ein unbekanntes Gerät anklicken.

     Klicken Sie in der Topologie mit der linken Maustaste das unbekannt/nicht übereinstimmendes Gerät, dessen Gerätebeschreibungsdatei Sie aktualisieren möchten, und wählen Sie IODDs aktualisieren.

   

3. Und schließlich in der Ansicht Topologiebearbeitung über die Funktion Gerät importieren.

     Klicken Sie IODD FINDER, um die IODD aus dem Internet herunterzuladen, siehe Download device description file from the Internet. Importieren Sie anschließend die IODD in den Gerätekatalog, siehe Import device description files und aktualisieren Sie sie für das Gerät über das Kontextmenü.

   

Continuously check connection status

You can continuously check the connection status of devices for scanned topologies.

  Activate the Consistently check connection status switch in the start screen.

  The connection status of the IO-Link network modules is continuously checked. The IP addresses of the connected devices are displayed. The current notifications are read out from the IO-Link network modules.

Compare parameters of two IO-Link devices in the configured topology

You can compare the parameters of two IO-Link devices with each other to quickly detect and rectify differences in the settings. Devices of different types can also be compared with each other.

Prerequisite: The IODD must be available for both devices at BET .

This is how you compare the parameters of two IO-Link devices in the same topology:

1. Hold down the Ctrl key to highlight the two IO-Link devices you want to compare.

  In the upper right corner of the main view, the * COMPARE DEVICES* button appears.

2. Click COMPARE DEVICES.

  The two devices are compared and the result is displayed in a dialog:

The two columns show the parameters of the two devices (source: [name of your BET project]).

3. Compare the parameter values of the two devices, see Compare device parameters with each other.

4. Click Apply Changes to apply the parameter selection and close the view.

To write the changed parameter values to the field devices, see Write parameters to device.

Save topology

You can save the current topology including the port settings of the IO-Link network modules and parameters of the IO-Link devices. You can then import the saved ZIP file back into BET at any time, see Import topology. If you save a topology, you have the following options for dealing with parameters that have been changed but not yet written to the physical device:

• ignore changes:
  

Parameters changed in the topology are saved in the topology file. When importing the topology, however, these parameters are not written to the physical devices, but only to the representation of the devices in BET. They then appear there without a status.

Example: Display of changed but not written parameters in topology before saving:

Example: Display of changed but not written parameters in topology after import (without state):

• Reset to current values:
  

Before saving, the changed parameters are overwritten with the current values of the physical devices.

Note

Discarded or reset parameter data cannot be restored.

• Write changes to devices:
  Before saving, the changed parameters are written to the physical devices.

Warning

DANGER OF ACCIDENT! By changing parameter data, switching points and data of IO-Link devices can be changed. Before resetting/writing the changes, ensure that the change cannot cause accidents or damage. The function must not be used if accidents/damage can occur as a result of reading/writing process data.
