◆ IedServer_getAttributeValue()

LIB61850_API MmsValue* IedServer_getAttributeValue	(	IedServer	self,
		DataAttribute *	dataAttribute
	)

Get data attribute value.

Get the MmsValue object of an MMS Named Variable that is part of the device model. You should not manipulate the received object directly. Instead you should use the IedServer_updateValue method.

Parameters

self	the instance of IedServer to operate on.
dataAttribute	the data attribute handle

Returns: MmsValue object of the MMS Named Variable or NULL if the value does not exist.

◆ IedServer_getBitStringAttributeValue()

LIB61850_API uint32_t IedServer_getBitStringAttributeValue	(	IedServer	self,
		const DataAttribute *	dataAttribute
	)

Get data attribute value of a bit string data attribute as integer value.

Get the value of a data attribute of type MMS_BIT_STRING. If the data attribute is of a different type the returned value is undefined. NOTE: The returned integer is determined by calculating the according the follwing formula: bit0^0 + bit1^1 + ... + bitn^n It is not specified in the IEC 61850 specifications how a bit string can be interpreted as an integer. Therefore this function has to be used with care.

Parameters

self	the instance of IedServer to operate on.
dataAttribute	the data attribute handle

Returns: the value a 32 bit integer.

◆ IedServer_getBooleanAttributeValue()

LIB61850_API bool IedServer_getBooleanAttributeValue	(	IedServer	self,
		const DataAttribute *	dataAttribute
	)

Get data attribute value of a boolean data attribute.

Get the value of a data attribute of type MMS_BOOLEAN. If the data attribute is of a different type the returned value is undefined.

		const DataAttribute *	dataAttribute
	)

Get data attribute value of a floating point data attribute.
