This article explores a method for executing data collection systems based on the widely-used industrial protocol, Modbus TCP. In this configuration, the server is a program emulating the Modbus TCP protocol.To implement the client an algorithm and furnished a practical Python programming illustration that employs a lower-level socket library.
Keywords: python, socket, modbus
The article discusses correlation methods of image identification. An algorithm of the "rare grid" method has been developed.

The article is devoted to the issues of accounting for various production disturbances that affect the temperature field in the drying chamber. The nature and nature of disturbances affecting the change in chamber temperature are taken into account using statistical methods for processing temperature curves over time. The temperature field in the plane of sensor installation was considered.In practice, the electrical model of the temperature field of the drying chamber can be represented as a three-dimensional grid, and the nature of the temperature field can be judged from the distribution of potentials at the corresponding grid nodes. By changing the grid parameters, it is possible to determine the appropriate temperature regimes for different materials and types of impregnations.

The article is devoted to the control system for the process of moving textile material in an apparatus for impregnating fabrics with periodic action. The control is implemented using a programmable logic controller (PLC). We consider a program developed in the Ladder Diagram (LD) programming language that implements motion control taking into account the change in torque.

The article discusses the issue of creating an automated system for detecting defects on tissue based on the use of computer vision. The resulting system makes it possible to control, register and calculate defects in textile materials without human participation in the technological process, which improves the quality of analysis, eliminates the number of errors in fabric sorting and reduces the cost of the technological operation.
