Аннотация

The article discusses the existing problems of centralized heat supply and considers the
forecast of the urban consumers’ needs of the Republic of Kazakhstan for the next decade. An
economic method for solving problems by applying complex automation process is presented.
A list of competitive suppliers of full-scale automated process control systems based on
modern software and hardware systems is given; a recommendation is made on their choice.
The advantages of using the Program Technical Complex “Krug” and the use of industrial
controllers DevLink-C1000 at the control objects (central heating stations, boiler rooms,
pumping stations, etc.) are described. Russian-made industrial controllers DevLink-C1000 are
designed to create “light” and “medium” automated process control systems, as well as used
as part of large, complex systems. In combination with DevLink A10 In / Out modules, the
DevLink C1000 controller is able to interrogate various sensors and devices (thermocouples,
thermoresistors, devices with a unified current output, etc.) and generate control actions.
PLCs can interrogate many different devices and read archives. A high-performance 32-bit
processor based on the ARM9 architecture (with a frequency of 400 MHz) in combination
with fast memory and a controller’s real-time system (SRVK) specially optimized for this
platform allow achieving a high level of performance.
