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.
