Data Acquisition

Data acquisition not only means transfer of information from peripheral devices to supervisory computers, but also transfer of information in the opposite direction, in order to allow the supervisory system to control the process, that is to direct its evolution by modifying the values of the variables that condition its operation.

We can say that data acquisition is the main function among those performed by SCADA systems. In fact, by putting the process in communication with the supervision, data acquisition makes it possible for the supervisory system to get all the information on the process status that are necessary to allow the observation of the process itself.

The task of data acquisition is to ensure the error-free transfer of information between process and supervision, in a context characterized by a variety of transmission media and different communication protocols. FOR MORE INFORMATION
