7.38.2 Common StatusCodes
Table 178 defines the common StatusCodes for all Service results used in more than one service. It does not provide a complete list. These StatusCodes may also be used as operation level result code. OPC 10000-6 maps the symbolic names to a numeric value and provides a complete list of StatusCodes including codes defines in other parts.

Table 179 defines the common StatusCodes for all operation level results used in more than one service. It does not provide a complete list. OPC 10000-6 maps the symbolic names to a numeric value and provides a complete list of StatusCodes including codes defines in other parts. The common Service result codes can be also contained in the operation level.

| Bad_NoContinuationPoints | The operation could not be processed because all continuation points have been allocated. |
| Bad_NodeClassInvalid | The node class is not valid. |

| Bad_ReferenceTypeIdInvalid | The reference type id does not refer to a valid reference type node. |
