  • Development of the system hardware and software configuration;
  • Development of the system functional software;
  • Development of technical and design documentation in compliance with the applicable standards and customer's requirements;
  • Purchase of components and manufacture of hardware;
  • System hardware and software integration;
  • Integrated system test;
  • Verification and validation;
  • Certification and licensing;
  • Delivery of system to customer;
  • System supervision on site;
  • Start-up;
  • System commissioning in compliance with the applicable rules and requirements of the customer;
  • System maintenance during its operation;
  • The above listed works are provided in the full scope or partially to meet the demands of the customer.

Black Sea group can supply a complete integrated, flexible and scalable control system, based on microprocessors which will ensure: monitoring, controlling, displaying, alarming, recording and supervising of inputs and outputs.

The system meets the base functional requirements:

  • expandability: system capability to be expanded more than offered basic system as following:
    • adding of new controllers and I/O modules;
    • adding of I/O signals to existing process controller;
    • adding of operation and engineering stations;
    • adding of peripherals;
    • on-line adding of opened / closed control loops through data acquisition functions, data processing, performance calculations, protocols, graphical displays.
  • reliability: system capability to operate in high reliability conditions and assure the following functions:
    • reducing to minimum of the failure period by on-line equipment and system diagnosis;
    • redundancy at levels of communication system, controllers, power supply.
  • maintenance:
    • hardware: system capability to on-line substitute the defect modules;
    • software: supplying necessary instrumentation for the system maintaining, re-configuring and re-loading. The system offers possibilities to on-line load the new versions of the base programs.
  • self-diagnosis: system capability to on-line self-diagnose during normal system operating without affecting system performances:
    • the diagnosis contains at least the software package and the supervising package for diagnosis (internal circuits and communication network). Graphical active images of the entire system, going up to the electronic card level, helps the operator to find out the failures and evaluate the system, processors and I/O modules working state. The type of perturbation / failure will be textually indicated, not in a code language. By this, the personnel is capable to carry out corrective actions or little repairs / replacements which will lead to an increased system availability;
    • all functional modules and supplying ones will allow to be replaced when the cubicle is under voltage and will have more indicator lamps to facilitate identifying and repair defect modules;
    • the system assures continuous operating of self-diagnosis and indication in CCT of the level where there are failures, by phonic signals and display on screen;
    • failures are identified at the module level in order to allow repairing / replacements. At putting under voltage or voltage reversion, the system will run an automation diagnosis procedure before real operating process;
    • possibilities of self-documentation and self-diagnosis of the system allows listing of all system elements, with present status indication and listing of all inputs / outputs signals for a certain module, including the spare circuits;
    • when a 5 W radio - receptor will operate at a distance of less then 1 m from the DCS equipment, radio - frequency interference won’t appear. Keeping the cubicle doors closed, it won’t appear changes among the analog values more then 0.5% of the calibrated domain.
  • security: system capacity to provide various security levels. The system has possibility to offer up to 6 security levels:
    • view only;
    • alarm acknowledge mode;
    • operator;
    • supervisor;
    • engineering mode;
    • manager.

    Each operator can have his own user name and password for having access to the operating station.
