InOut:

Name	Type	Comment
nRefSequenceNum	IEC_BACNET_UNSIGNED	The ‘Reference Sequence Number’ parameter specifies the sequence number of the first (if ‘Count’ is positive) or last (if ‘Count’ is negative) item to be read.
nCount	IEC_BACNET_SIGNED	The absolute value of the ‘Count’ parameter specifies the number of records to be read. If ‘Count’ is positive, the record specified by ‘Reference Sequence Number’ shall be the first and oldest record read and returned. If ‘Count’ is negative the record specified by ‘Reference Sequence Number’ shall be the last and newest record read and returned. ‘Count’ shall not be zero.
