To use the automatic scanning of events, users must enable the automatic scanning on the configuration window of this Driver. Users must also configure the scan period and the scan delay among Tags. At every scanning period, this Driver starts scanning all Tags registered for automatic reading of events, with a delay between every reading. The delay among Tag readings allows balancing the internal scan load, thus avoiding to overload applications and communication channels at every scan.

The first reading operation of any Automatic Scanning of Events Block Tag does not return values, that is, returns an empty list, it is only intended to internally register that Block Tag in this Driver's automatic scanning mechanism. No property of that Block Tag is changed. Then, that Block Tag starts to be included in each automatic scanning of events. The next readings start to return the collected values, whenever they are available in the internal buffer of this Driver. Scan times of automatic scanning of events in an application can be low, such as 100 milliseconds. As these Tags do not generate communication with a device, their CPU consumption is low.
