A Device (component) is defined in the Wiring Manager Device Catalog. This can be a Relay, IS Barrier, I/O Modules, Power Supplies or any other 'black box' with terminals.
Although devices can be added to almost any equipment item, it is more usual to group devices together on rails. In Wiring Manager DIN Rails offer a convenient method of grouping devices and/or terminal strips together in a user defined sequence.
-
To add a device, do one of the following:
-
In the Equipment Layout window, right-click on any DIN Rail or existing component, and then select Add Device.
-
Right-click on an appropriate equipment node in the Equipment View, and then select Add Device.
-
Right-click on any Equipment in the Cable Block Diagrams window, and then select Edit Detail to open the Global tab window.
The Device Information window opens.

-
-
Enter a Device Tag/Description.
-
Select Select from Catalog, and then select a device from the Wiring Manager Device Catalog.
For further information, refer to Select Device from the Catalog.
-
(Optional) Select a new or existing Status.
-
Enter a Sequence number (defines the sequence the device will appear on the DIN Rail).
Note: The sequence is not viewable in this window if you are creating or editing a Device from the Wiring Manager Equipment Layout window. When adding a new Device in the Layout window, the sequence is defined by the position in which the component is added. To change the sequence in the Layout window, drag and drop the component to a new position (sequence).
-
To rotate the device 180 degrees (that is, place it upside down on the rail with respect to its catalog definition), select Rotated.
Once a device is selected, the Catalog Information fields display the Model No, Manufacturer, and Description. In addition, the graphic is updated to show the terminal arrangement of the selected device. For example:

Note: Device information is fixed for each specific catalog entry. You cannot edit device information from project equipment. You can only edit/add devices from the Wiring Manager Device Catalog. Also, if a catalog definition is changed in the Device catalog all the project instances are changed to the new definition.
-
Click Save to save the new device to the parent equipment (or DIN Rail).
