The article discusses the implementation features of the open network architecture NET Linx in the Control Logix system. The analysis of the operation of the main types of networks included in this architecture of communication protocols in the framework of a standard three-level model of an automated process control system of an industrial enterprise is carried out. As a model for research and analysis, the Control Logix 1756 platform based on the 1756-A4 chassis with 1756-ENBT, 1756-CNB, 1756-DNB Series C switching modules and 1756-L55 processor was adopted. This configuration allows data transfer via Ethernet IP, Control Net, and Device Net protocols, which are related to the levels of operational control, automatic control, and input/output, respectively. The main scientific interest is the end-to-end transmission of information from the automatic control level to the input/output level, as well as the features of data conversion during transmission from one level to another, the effect of these transformations on the amount of delay in data transmission and throughput. The last parameters will be given special attention, since the system reaction rate and the stability of the delay value are key parameters for the operation of the automated process control system as a whole.

Keywords:network, architecture, automation, technological process, mining, NET Linx, Control Logix.
