Semantics
Register Data
Within the response of a Get_Attribute_Single Service to the „Register Data“ Attribute the status of the internal reading and the registers data is returned by the ILxxxx-B520. The meaning of the registers data is described in the ILxxxx-B520 manual.
Within the request of a Set_Attribute_Single Service to the „Register Data“ Attribute the Low-Word of the attribute „RegisterData“ is used to send the Register data to the ILxxxx. The meaning of the registers data is described in the ILxxxx-B520 manual.

IL_Status
The „IL Status“ attribute shows the actual status of the ILxxxx-B520.
| Byte | Bit 7 | Bit 6 | Bit 5 | Bit 4 | Bit 3 | Bit 2 | Bit 1 | Bit 0 | 
|---|---|---|---|---|---|---|---|---|
| Byte | FB_Error | res. | res. | res. | Diag | res. | IL_Cfg | IL_Error | 
IL_Error : IO Error, internal Data exchange ILxxxx-B520 has failed
IL_Cfg : ILxxxx-B520 Configuration Error (EEPROM check failed)
Diag : Diagnosis of analog Channel
FB_Error : Fieldbus Error / Idle Mode
Extension Box Diagnosis
The „Extension Box Status“ attribute describes which of the extension boxes has encountered a diagnosis event.
|  | After reading the extension box Status, the attribute is cleared until the next diagnosis appears. Reading of the attribute also clears the “Diag-Bit” within the attribute “IL Status”. The function of this attribute is only active if the diagnosis of analog extension boxes is enabled. | 
| Byte | Bit 7 | Bit 6 | Bit 5 | Bit 4 | Bit 3 | Bit 2 | Bit 1 | Bit 0 | 
|---|---|---|---|---|---|---|---|---|
| 0 | Extension Box Number | |||||||
| 1 | Status | Error Code | Channel Number | |||||
Extension Box Number : Number of failed extension box
Channel Number : Number of failed channel of the extension box
Error Code : Extension box specific Error Code (see extension box manual)
Status : 0 = Error is reseted
1 = Error occurred
IO Error Action
Action to be performed if a fieldbus error occurred.
|  | To activate a new IO error Action setting a device reset has to be performed either by executing a power cycle to the ILxxxx-B520 or by executing a Reset Service (Service Code 5) to the ILxxxx-B520 Identity Object (Class Id 1, Instance 1) | 
| Value | Description | 
|---|---|
| 0 | Leave local IO Cycle | 
| 1 | Leave local IO Cycle and reset outputs (default) | 
| 2 | freeze outputs | 
Poll produced data type
COS / Cyclic produced data type
Poll / COS / Cylic consumed data type
Type of IO data produced/consumed via the Poll mode and Change of State / Cyclic mode.
| Value | Description | 
|---|---|
| 0 | Analog and digital IO Data with Status Byte (default) | 
| 1 | Digital IO Data with Status Byte | 
| 2 | Analog IO Data with Status Byte | 
Bit Strobe produced data type
Type of IO data produced via the Bit Strobe mode.
| Value | Description | 
|---|---|
| 0 | Diagnostic Data (see Attribute extension box diagnosis) | 
| 1 | Digital Inputs with Status Byte (default) | 
Device Diagnostics
Enables Diagnostics of complex (analog/special function) extension boxes. Setting this attribute enables the diagnosis of complex channels which is needed to read the extension box diagnosis.
|  | To activate the diagnosis functions a device reset has to be performed either by executing a power cycle to the ILxxxx-B520 or executing a Reset Service (Service Code 5)to the Identity Object (Class Id 1, Instance 1). | 
| Value | Description | 
|---|---|
| 0 | Device Diagnostic OFF (default) | 
| 1 | Device Diagnostic ON | 
Bus Off Behavior
Defines the Behavior of the ILxxxx-B520 after detection of a Bus-Off event.
This attribute is available from Firmware Revision 1.2 upwards.
| Value | Description | 
|---|---|
| 0 | Hold the ILxxxx-B520 in Bus-Off State (default) | 
| 1 | Reset ILxxxx-B520 and restart communication. After detection of 255 Bus-Off events the ILxxxx-B520 keeps in the reset state. |
