Note Ensure that the configuration cable is not laid in close
proximity to high power electrical drives or cables carrying 
high power. In this way you will avoid EMC effects on the 
configuration cable.
Note When devices—consisting of senders and receivers—are
involved, initially connect the receiver because it needs to 
be configured first.
The Project Tree
The project tree of the devices is shown in the navigation area.
The devices existing in the project tree can be displayed in the 
“active” or in the “passive” mode:

The device status is symbolized by the color of the lettering:

Changing Project Names
You can change the name of a project. When a project is saved, the 
SCD uses the project name as the default file name. For the project 
name, use names, for instance, with which you can allocate your 
projects to the machines or equipment that are protected.
Example Symbols
Meaning
Active devices are shown in color.
Active means that the device has a 
complementary unit to which a 
connection has been made via the 
interface and that the complementary 
unit has been identified by the SCD.
Passive devices are shown in gray.
Passive means that there is at present no 
connection to this device, either because 
it is currently disconnected or because it 
could not be identified. This is important 
particularly in devices such as the 
SafeShield safety light curtain that 
consists of sender and receiver. As the 
PC with the SCD can be connected only 
to the sender or the receiver, the 
complementary unit is always shown in 
the passive mode.
You can identify the device to which the 
PC is connected by the device symbol 
showing a PC.
Unknown or unidentified devices are 
shown with a question mark.
Font Color
Meaning
(Blue) [protective device]
Configured devices are shown with blue 
lettering.
(Red) [protective device]
Nonconfigured devices or devices in 
which a malfunction has occurred are 
shown with red lettering.
(Grey) [protective device]
Devices where the SCD is unable to 
identify their status (not connected, not 
identified) are shown with grey lettering.
Comparing with a Project File
You can also compare a project saved and/or opened in the SCD 
with a saved project file.
A dialog box will show the saved project on the left and on the 
right a comparison protocol.
In this dialog box you can open the project file compared with the 
open project.
Adding Devices
If you have created your own project in the SCD, you can also add 
one or several devices. The device selection wizard will assist you 
in this step.
The class of devices you can select there will depend on which 
device classes have been installed.
Added devices can be deleted again from the project.
Properties
To check the type codes and the serial numbers of the devices, you 
can display the properties of a project and/or the properties of a 
single device. The list shows all type codes and the serial numbers 
of the devices.
Communication
The software communicates with the devices via a cable link. To 
make sure that the data communication between your PC and the 
connected devices functions properly, you must select a 
communication protocol.
IMPORTANT
The commands necessary to carry out the 
above-described functions are found in the 
context menu of the project. Please refer to the 
online help for detailed instructions.
IMPORTANT
On the Extras menu of the SCD, you will find 
the Communication connection... 
command. Please refer to the online help for 
detailed instructions.
