Table 177 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 178 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.

Table 178 – Common Operation Level Result Codes

Symbolic Id Description
Good_Clamped The value written was accepted but was clamped.

This status is returned if the continuation point was deleted or the address space was changed between the browse calls.
Bad_DataEncodingInvalid The data encoding is invalid.
This result is used if no dataEncoding can be applied because an Attribute other than Value was requested or the DataType of the Value Attribute is not a subtype of the Structure DataType.
