Abstract
The article is devoted to the description of the developed information and measurement system of the control node of the main heat pipeline, implemented within the framework of the project "Development of an intelligent big data processing system (Project 63396, application STI 83270)". The control unit is implemented on the basis of the WAGO 750-882 PLC. The article describes the composition of the measuring system, an assessment of the uncertainty of the measurement result for each measuring channel is carried out. An algorithm for processing measurement information and transmitting it to a PC for a WAGO750-882 PLC is described. The description of data transmission to the information system is given.
