OPC UA Detected Error Code Structure
OPC UA detected error codes are 4 bytes long of the DWORD data type.
OPC Foundation
PLCopen or Schneider Electric
Field |
Bit Range |
Description |
||
|---|---|---|---|---|
Severity |
30:31 |
Indicates whether the detected error code represents a successful, unsuccessful or or uncertain condition, as follows: |
||
00 |
Successful |
The operation was successful. The associated results can be used. |
||
01 |
Uncertain |
The operation was not successful. The associated results cannot be used. |
||
10 |
Unsuccessful |
The operation was partially successful. The associated results might not be useful for some purposes. |
||
11 |
Reserved |
Reserved for future use. It is recommended that clients treat a detected error code of this severity as unsuccessful (10). |
||
ErrorType |
29 |
0 |
Indicates an OPC Foundation defined detected error code. Refer to the OPC UA specification for a description at: https://reference.opcfoundation.org/v104/Core/docs/Part6/A.2/ |
|
1 |
Indicates a PLCopen or vendor specific detected error code, signalled by bit 28. |
|||
ErrorType2 |
28 |
This bit can be evaluated only if bit 29 = 1. |
