Abstract. Modern industrial enterprises have a four-level management system: the 4th level is the resource planning system, the 3rd level is the production process management system, the 2nd level is the process control system, the 1st level is the field level, the level of primary converters. The communication at the 4th and 3rd levels is carried out via optical cables and cables with copper cores for structured cable networks. The communication at the 2nd level is carried out via cables with copper cores for structured cable networks, and a specialized cable is used to connect the programmable logic controllers.
For the connection of the 1st level objects several increasingly complex automation systems have been developed and used: “current loop 4–20 mA”, “HART protocol”, systems with an information transfer rate of 31.25 Kbit/s, such as “Profibus-PA” and “Foundation™ fieldbus“,“RS-485”, and systems based on the Ethernet technology are being tested.
For the automation systems the “current loop 4–20 mA” and the “HART protocol” the communication is carried out via any low-frequency cables, for the automation systems “Profibus-PA” and “Foundation fieldbus” the communication is carried out via cables operating in the frequency range up to 39 kHz.
For the automation systems “RS-485” the communication with the field devices is carried out via cables operating in the frequency range from 10 MHz to 100 MHz.
For the automation systems based on the Ethernet technology the communication is carried out via cables for structured cable networks of category 5 and higher.
The NPP “Spetskabel” produces copper core cables for all levels of the control system and all automation systems of the 1st level of control.
Key words: four-level control system, connecting cables for automation systems, “current loop 4–20 mA”, “HART protocol”, “Profibus-PA”, “Foundation™ fieldbus”, “RS-485”, Ethernet technology
