In the paper, the issues of modeling information technology for remote monitoring of technological processes and objects with the ability to control the state of monitoring objects are considered. The main objectives and constraints in the form of ISO/IEC/IIC standards and recommendations have been defined. According to the structural analysis and design methodology, a set of input and output parameters, mechanisms, and constraints affecting operations and data flows have been defined. A conceptual model of information technology for monitoring systems has been built and decomposed in the IDEF0 notation, the possibility of its implementation is shown using the example of a data acquisition unit in the form of an intelligent router that provides collection, processing, temporary storage of data and communication with a data processing server.
