Hybrid logic Controller For Servo Systems Based on S7-1200 Programmable Logic Controllers

In the article, based on a critical analysis of the existing hybrid logic controller for servo systems, which consists of: mechanical, analog and digital blocks (Feerdback 33-100, Feerdback 33-110 and Feerdback 33-120), in order to increase the functional capabilities and simplify its use, a hybrid logic controller is proposed, which consists of the above-mentioned mechanical block, S7-1200 programmable logic controller, functional/arbitrary generator Hunteck 1225 and mixed signal oscilloscope Pico scope 2205, where analog impact signals are generated by the Hunteck 1225 generator, digital impact signals are generated and the received signals are processed by the signature circuit implemented in S7-1200. analysis methods, and the received analog signal is processed by means of analog analysis implemented in S7-1200, in addition: • When controlling with analog signals, the method of generating analog signals using the functional/arbitrary generator Huntec 1025G and their input to the PLC was developed; • An algorithm for analyzing analog signals in the TIA Portal programming environment with SCALE_X and NORM_X instructions was developed. • An algorithm using the parallel digital signature analysis method for multi-level digital systems in the TIA Portal programming environment was developed; • A laboratory course for undergraduate, graduate and doctoral students will be developed with the research and experiments conducted in the laboratory. The course can also be used for students of professional training. The unified theory of analog and digital control systems will allow students to study fundamental concepts in a single course.Keywords: servo system, mechanical block Feerdback 33-100, analog block Feerdback 33-110, digital block Feerdback 33-120, programmable logic controller S7-1200, functional/arbitrary generator Hunteck 1225, mixed signal oscilloscope 2205, analog analysis, signature analysis
