The proposed duplicated data processing system contains a main programmable logic controller and an additional programmable logic controller. The controllers are connected to the controlled object by a serial communication line. The main controller contains a control processor, a multichannel input unit for discrete signals, a multichannel input unit for analog signals, and a multichannel output unit for analog signals. The additional controller contains a data acquisition processor, a multichannel input unit for discrete signals, a multichannel output unit for discrete signals, and a multichannel input unit for analog signals with a frequency-to-currant converter. The proposed system provides acquisition and storage of data, generation of control signals, and the possibility to process discrete and analog signals, resulting in the improved reliability and simplified design of the system.
