6.2.6 Audit collect

The audit collect collects audit data from all components providing audit Events and makes them available for external access. A Vending Machine according to this specification supports exactly one audit collect, and in addition optionally one tax audit (see 6.2.7).

The audit collect provides its interface by implementing an instance of the AuditCollectType (shown in Figure 15, defined in 7.25). The optional Components Object of BaseComponentsType defined in 7.4 can provide information about subcomponents of the audit collect. The audit collect requires OPC UA Client functionality to access audit information of the payment service, the standalone payment devices, the UI(s) and the machine engine(s) of the Vending Machine.
