5.5MeterFunctionObjects / companion specifications配套规格

With reference to Figure 1 it can be seen that the TokenCarrierToMeterInterface, which also includes the TokenCarrier, is dealt with in the IEC 62055-4x and IEC 62055-5x series. The remaining MeterFunctionObjects shown in the diagram are defined in companion specifications and are not normative to this document.

        参见图 1，可以看到，TokenCarrierToMeterInterface（其中包含 TokenCarrier）在 IEC62055-4X和 IEC62055-5X系列上有涉及。在此图中见到余下的 MeterFunctionObjects，在配套规格上有定义；但对本标准来说，它们并非已经标准化。

Companion specifications (see Figure 2) are under the administrative control (see Clause C.9) of the STS Association and serve the purpose of defining functionality of a payment meter in a standardized way, using an object-oriented approach.

        配套规格（见图 2），由标准传输规格协会管理控制，见 C.8。它用于定义付费电表功能（标准化），并采 用面向对象的方法。

 5.6 Transaction reference numbersISO 交易参考号码

The transaction reference number comprises the data elements and their relationships as shown in Figure 5.
        ISO 交易参考号码的组成包括数据元素及其关系，见图 5。
A token-based transaction (see Clause 3) constitutes a financial activity that needs to be dealt
with in accordance with standard financial practices.
        以令牌为基础的交易（见第 3 节）是一种财务活动，需要遵循标准财务惯例。
The PrimaryAccountNumber (PAN) serves to tag transaction records, messages, requests,
authorizations and notifications, in which both transacting parties are uniquely identifiable.
        PrimaryAccountNumber(PAN)，在 ISO/IEC7812-1 中有所定义，标识交易记录、信息、请求、授权和通知，其 中交易双方可以唯一被识别。
A payment meter is thus uniquely associated with a MeterPAN, being a composite number comprising of IIN and IAIN / DRN, which in turn comprises MfrCode and DSN (see 6.1 .2).
        因此，付费电表和 MeterPAN 具有独特的联系。MeterPAN 是一个合成号码，由 IIN 和 IAIN/DRN 组成。反过来，它可以组成 MfrCode 和 DSN，见 6.1.2。
