The article discusses the question of a rational organization of the input — output operations for a highly dynamic digital control system (DCS). The required dynamics of DCS is achieved through a transfer of the input — output operations into a separate hardware node — an active peripheral subsystem. The developed model of the consistent information environment for DCS allows a more precise evaluation of all the phase durations of the control cycle and simplifies the logic of interaction between the parts of the software management cycle. Organization of the input — output data with simple cyclic operations in a non-conflict mode allows us to maximize the speed of operation in all the phases. Another advantage of the architecture of the input-output subsystem is the ability to simultaneously capture the state of all sensors in the current cycle regulation — getting a "snapshot" of the state of the controlled object. This result also demonstrates a rational improvement of the overall performance of all the operations of the exchanges with the periphery, but not of the speed of operation of the individual transactions with in one control cycle.
