  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 temperature system on base DS1631 has proved its reputation as simple and reliable. In how intense ionizing radiation the system can remains operational for a long time? To answer this question the set of temperature sensors was placed at the converter of VEPP and the measurements have been adding to our DB every minute during one month. A dose of ionizing radiation had been registering every 3 days. The results of this experiment are described in the article.  
WEP095 Architecture of VEPP-4M Collider's Interlock System 1

  In recent years we have been building a complete Temperature Measurements and Interlock System to prevent an overheating of magnets. The system provides warning and interlocking functions. The article describes the method of collecting and processing temperature data and the information panel of Interlock System.

  The VEPP-4 Control System is based on using CAMAC-embedded controller ODRENOK, which was designed 25 years ago*. In 90th PCs were implemented into the control system for data storing and visualization**. Since this period a lot of new devices and technologies were accommodated for the accelerator control on the VEPP-4 facility. This paper includes a description of the recent experience of the VEPP-4 control system operation based on communication of PCs with old computers. Automation of the operations on the high energy physics experiments is presented. The long time data storage system based on postgreSQL server is described.
