Refinery Telecontrol system


The refinery telecontrol system is designed for monitoring and control of pipelines within refineries and between them. The system provides safe operation from a single control station.


The telecontrol system has three-level architecture.

Control Room Level:

  • I/O servers with redundancy support;
  • Operator and engineer workstations;
  • Communication and office equipment.

PLC level:

  • Programmed logic controller;
  • Intrinsically-safe converters;
  • Uninterrupted power supply system;
  • Surge and lightning protection devices.

Field device level:

  • Sensors, actuators and valves;
  • Fire and security alarm and access control subsystem;
  • Container house utility subsystem;
  • Electrochemical protection devices.

Main Features

  • Monitoring of major and auxiliary process equipment;
  • Data processing and transmission to control software (SCADA) via industrial networks;
  • Control commands processing and transmission to actuators and other field devices;
  • Monitoring and control of fire protection and security systems;
  • Remote configuration of operation modes via industrial networks;
  • Data exchange via telecommunication channels;
  • HMI and process visualization;
  • Process data archiving with historical data access capability.

The telecontrol system has a distributed architecture, consisting of operation control center and remote control stations, connected via telecommunication channels.


  • Flexibility

The system is designed to ensure scalability in hardware and functionality.

  • Functionality

The telecontrol system components provide for additional operation modes (simulation, testing, masking) and other features, such as unauthorized access protection and event logging to monitor personnel actions.

  • Compatibility

The system provides better integration with third party systems.
