报告控制块中 RptEnabled 对于多个客户机的实例化要求

The element RptEnabled is defined as follows:

 

The RptEnabled element contains the list of client LNs for which this report shall be enabled
(for example at IED startup on pre-established associations).

The attributes given in Table 23 are used.

 

According to IEC 61850-7-2, a report control block is dedicated to at most one client at a time.
This means that if Max > 1 is given for RptEnabled, more than one report control block (RCB) of
this type has to be instantiated in the IED. Observe that for all buffered control blocks, a ClientLN
shall be preconfigured, i.e. Max is identical to the number of ClientLNs given. If ClientLNs are
preconfigured for unbuffered RCBs, then the Resv (URCB Reservation is described in
IEC 61850-7-2) attribute of the RCB shall be set to true additionally to the RptEna attribute
(Report Enable is described in IEC 61850-7-2) in the IED. The URCName or BRCName of the
control block according to IEC 61850-7-2 is built from the RCName attribute above followed by a
two digit number between 01 and Max. If ClientLNs are defined, the index (position) of the
ClientLN in the list contained in the RptEnabled element is used as this number for this client (the
first has index 1). This means that a report control block definition in SCL has to be considered as
a type, and not as an instance, which might have 99 instances to 99 clients.

 

报告控制块与客户连接是单对单，每次只允许一个客户使用该控制块。如果Max>1，则需要生成多个实例。实例用名称+index的方式生成。此时在SCL文件中RCB看成是个一类型，而不是一个实例，如果有MAX个客户就要生成MAX个实例。

The ClientLN element defines the name of a LN in the system, which is a client to this report
CB type.

Restrictions
The name of the report control block shall be unique within the LN.
Note that to identify a LN within the system, the IED based designation is used here, even if the
communication name generation is based on the substation functional structure. It is
recommended that a tool assures that the defined client is really accessible across the defined
communication system.
For pre-established associations, the AssociationId corresponding to the referenced LN can be
found in the association definition section of this IED.

 

 

 

The RptEnabled part defines that the Report control block type is valid for 5 (unbuffered) RCBs
with names PosReport01, PosReport02, up to PosReport05. The first one, PosReport01, is
already reserved for the client A1KA1LD1/IHMI1. All reports are triggered with dchg and qchg,
and the buffer time is 0. No OptFields are defined, i.e. only the mandatory information is
included in the report.

解析结果，需要根据max的值，生成相应个数的实例。
