HDLC简介-DLMS-結構解析

HDLC简介HDLC地址就是我们常说的通讯地址HDLC地址分源地址、目标地址两种HDLC地址有如下三种表示方式t1个字节：用1个字节的Upper HDLC address进行通讯（0~7F） t2个字节：用1个字节的Upper HDLC address和1个字节Lower HDLC address同时进行通讯(0~3FFF) t4个字节：用2个字节的Upper HDLC address和2个字节Lower HDLC address同时进行通讯(0~FFFF) t　　 * This information is contained in a special COSEM object, the “association” object. There are two types of this association object defined. One for associations using short name referencing (“Association SN”) and one for using logical name referencing (“Association LN”). Depending on the association established between the client and the server different access rights may be granted by the server. Access rights concern a set of COSEM objects – the visible objects – that can be accessed (‘seen’) within the given association. In addition, access to attributes and methods of these COSEM objects may also be restricted within the association (e.g. a certain type of client can only read a particular attribute of a COSEM object). The list of the visible COSEM objects – the “association view” – can be obtained by the client by reading the “object_list” attribute of the appropriate association object. Additional information about the access rights (read only, write only, read and write) to the attributes and the availability of the methods (within the established association) can be found via specific attributes (Logical name referencing) or special methods (Short name referencing) provided by the association objects.
