5.1 Modelling concepts ToC Previous Next

The base interface concept of the AutoId information model shown in Figure 4 supports two different communication procedures. One procedure is to trigger the scan from an OPC UA client and the other procedure is that the AutoID Device sends a scan event whenever the AutoID Device detected a tag or code.

The AutoIdDeviceType provides the method Scan to trigger a scan and to return the scan result with the Method response. In addition the ScanStart provides a way to start the scan but to receive the scan result through an AutoIdScanEventType.

The AutoIdScanEventType defines the information provided with a scan event and it is either triggered through a ScanStart Method call or through the AutoID Device itself.
