| Acquisition and control of internal and external data (DAQ) | |
Different types of logical and physical sources that have data access utilities or accessible through simple and specialized network protocols. This is accomplished by writing a data acquisition procedure of the user protocol in the user programming language. Most known protocols implementing on the user protocols:
