Data acquisition and data transmission technologies (DAQT) are introduced together with their principles and typical applications. ISO/OSI model for distributed system is explained and basic characteristics of physical (metallic, optical and radio) communication channels are provided. Intelligent transducers are introduced and basic data transmission models are explained. Simple communication interfaces are described as well as more complex fieldbus and computer network standards (both the wired and the wireless) that are used for the DAQT applications. Basic information is also provided about the systems installation and exploitation including their EMC.
