Simple synchronous acquisition mechanism

The mechanism is characterized by requests to the data source synchronously with the request to the parameter attribute (Fig. 2). This mechanism is usually used when working with local data sources, characterized by low latency, i.e. delay in response to the request. With this method you can get actual data directly with the request, but the time of the request of the object will include the time for transportation and processing of the request by the data source.
