In this case, check the entries for class, instance and attribute, the DeviceNet connection and the configuration.
6.In the "Description" dialog box, select the "Set Single Attribute" utility and enter the following values in the "Object Address" dialog boxes:
- "Class": 4
–"Instance": 64 (64 hexadecimal = 100 decimal)
–"Attribute": 2.
7.Click in the " Data Sent to the device" dialog box and enter the following values in hexadecimal:
10 00 06 00 20 A6 24 01 30 01 10 00 06 00 20 A6 24 02 30 01
The path is described by:
0x20 CC (Class) 0x24 II (Instance) 0x30 AA (Attribute)
8.Click on the "Execute" button to define the mapping.
If the mapping was successful, the fieldbus node sends a “performance” confirmation.
If a fault has occurred, you will receive a fault message.
In the event of a communication or reply fault, check the DeviceNet connection and whether or not the instance was correctly set.

9.Click on the "Close" button. The dialog window is closed.
10.To parameterize the Controllers, double-click on the graphic symbol of the fieldbus node 750-806.
11.Select the "Parameters" register and “All parameters” in the "Groups" dialog box.
12.Use the scroll bar to move down to the ID#13 and #ID14 addresses.
ID#13 is a pointer for the inputs (Default = 4).
This parameter is changed when the inputs are mapped for the master. This is not required due to the fact that the inputs are only read and not written.

ID#14 is a pointer for the outputs (Default = 1).
This parameter is changed in order to point on the dynamic mapping of the outputs that are mapped in the dynamic assembly instance 100dec. (0x64hex).
13.Do not change the pre-set standard value 4 of the ID#13.
Enter 25604 decimal for the ID#14 to direct the pointer on the dynamic assembly output mapping.
The value 25604 corresponds to the hexadecimal writing 0x6404. 04 (Low Byte) = Class type
64 (High Byte) = 100 decimal instance number
14.Change the value for the ID#39. Select "Dynamic created instances are stored in non volatile memory", to retain the storage of the configuration for the Dynamic Assembly even following a voltage failure of the Controller.
15.To take over the pre-set parameters into the Controller, select the following parameter in the right-hand control box in the "Parameters" register:
"All Values", then click on the "Download parameters to the device" symbol which is located on the far right next to the dialog box.
16.Confirm the setting by clicking on the "OK" button. The dialog window is closed.
17.Then switch the supply voltage of the Controller off and on again. Now the fieldbus node is ready for networked communication.

The Controller starts after switching on the supply voltage. The "I/O" LED flashes red. Following an error free start up the "I/O" LED changes to green steady light.
In the case of a fault the "I/O" LED continues blinking red. The fault is cyclically displayed with the blink code.
