In this paper attempted to evaluate the risks of using the base protocol IEC 870-5-101 and identify opportunities to create effective redundant remote control systems. Made an analysis of the implementation of redundant devices controlled points systems with concentrated and dispersed intelligence. In the first embodiment, program modules and processing equipment, the validation information to the binding timestamps are concentrated in the central controller. In the second embodiment, input-output procedure and processing are carried out directly in the function module, and central controller implements a dispatch function for transmitting and receiving information from the communication lines to the control point. Proved the possibility of organizing a “hot” backup in the formation of informational messages central controller device controlled point. Shown that the method of formation of autonomous components underlying protocol modules-sources of information increases the efficiency and reliability of information.
