Answer Posted / asif iqbal
Traditionally, DCSs were large, expensive and very complex
systems that were considered as a control solution for the
continuous or batch process industries. In large systems
this is, in principle, still true today, with engineers
usually opting for PLCs and HMIs or SCADA for smaller
applications, in order to keep costs down.
A correctly designed DCS control system is essential for
the safe and efficient operation of a process plant.
Process Technical Services can provide qualified and
experienced instrument and control system engineers and
technicians that will review the P&I diagrams in detail to
determine if the DCS control system will meet the needs of
your operations.
SCADA Supervisory Control and Data Acquisition systems
which provide automation control over large industrial and
commercial operations providing real-time data transmission
by telemetry from remote location sensors for processing
and analysis resulting in a feedback loop for computerized
control over system operations
