The modern classical architecture of a control system includes three levels: client application level, server level for synchronization of data exchanges and hardware level, which includes hardware drivers. There are two different types of data exchange in the three-level control: between client and server levels and between server and hardware levels. The concept of "channel" maintains the both types of data exchange. The channel implementation connects a physical characteristic of a controlled facility (in the client level) with a corresponding value in an electronic device. The presented paper describes a two-level channel model, which includes the difference between the data exchange types. The two-level channel model separates the specific attributes of the data exchange types and provides a flexible interface between a physical characteristic of a facility and an implementation of electronics. The model includes two levels of channels: client channels connected with facility physical characteristics and hardware channels connected with electronics. A description of channel types, relations between two levels and an exchange protocol project are presented in this paper.

The paper presents architecture, implementation and functionality of injection channels control system for VEPP-2000 collider. The software according to hardware system consists of different interacting subsystems responding on different injection channels parts. The paper describes structure and implementation of the hardware of the collider control system. The system consists of pulse-elements; steering coils power supplies and nanosecond high-power inflectors (60 kV, 20 ns). The system is based on modern industrial protocol CAN-bus, CAMAC standard and specialized electronic BINP manufactured blocks according the standards. Software for the control system is based on several TCP/IP connected PC platforms working under operating system Linux and uses client-server techniques. CAN and CAMAC servers; different clients for control and power supply measurements; inflector control tools and their interaction with the rest of VEPP-2000 control system are described.

Electron-positron collider VEPP-2000 is under commissioning at Budker Institute of Nuclear Physics. The paper presents architecture, implementation and functionality of the software of the collider control system. The software according to hardware system consists of interacting subsystems responding on different acceleration facility parts. Control system software is based on several TCP/IP connected PC platforms working under operating system Linux and uses client-server techniques. The paper describes implementation, operating possibilities and perspectives of VEPP-2000 software. The paper also presents structure, architecture and implementation of the hardware of the collider control system. The system consists of pulse-elements, steering coils power supplies, high-current main field power supply, RF subsystems and some other special subsystems (such as vacuum, temperature, etc. control subsystems). The system is based on modern industrial protocol CAN-bus and specialized electronic BINP manufactured blocks according the standard. The paper describes implementation of different subsystems based on CANbus devices, and operating characteristics and possibilities.
