Returns the value of the one or more specified attributes of an application instance. The instance is specified by its numeric instanceID that uniquely identifies it in the remote EDMdatabase, these attributes are identified by their attributeIds. For each attribute value to read the following three arguments must be specified: <attributeID>, <valueType>, <value>

Arguments

Type	Name	Comment
SdaiServerContext	serverContextId	Context identification, from edmiDefineServerContext
SdaiInstance	instance	A numeric instanceID that uniquely identifies the instance of interest in the remote EDMdatabase
SdaiVersion	version	The version of the edmModel to apply this function call on. The <version> parameter is a numeric sequence number counting from one by increments of one for each new model version that is created. A zero model version number means the current version.
SdaiInteger	numberAttr	The number of attributes for which to to assign values.
SdaiInvocationId	edmiInvocationId	Currently not used.
SdaiAttr	attributeID	The numeric attributeId that uniquely identifies the attribute definition instance in the remote EDMdatabase.
SdaiPrimitiveType	valueType	The primitive type of the attribute. This type must be the same as the actual data type of the attribute value or any compatible data type. The primitive type sdaiSELECT can be used to get all data types. The primitive type sdaiADB can be used to get all data types except typed values. The primitive type sdaiINTEGER is compatible with sdaiREAL, and sdaiBOOLEAN is compatible with sdaiLOGICAL, hence conversion between these compatible data types will be performed automatically when required. <value> : The
void	value	variable that will hold receive the data value from the actual attribute.
