PLANT AUTOMATION
At INDPRO, being a project engineering company
our prime focus is on providing full-proof and
dependable solution. Hence, we have provided control
systems using Programmable Logical Control (PLC)
and Relay based control systems.
We do know that building, operating, and maintaining
an industrial plant site is difficult and challenging
at best. Many times events present difficult challenges
because experienced personnel may be limited.
Observations are the human intervention in the
plant or process has limitation on various fronts
with the main concern being; reliability and human
error. Teaming with semi/full automation can help
overcome these challenges in a cost effective
and timely manner.
A control system is required to monitor product
passing through various stages of manufacturing
processes, during those stages it requires a kind
of control in order to adjust the quality &
quantity of it. However, to adjust this, it is
required to control many physical quantities such
as pressure, Temperature etc.
Further more, in some dangerous applications such
as petrochemical factories and nuclear reactors
the control becomes much critical, however, losing
control here will be disastrous. Here control
systems and automation have proven their worth.
Basically, control system receives input signals
from other devices, these signals will be here
are many sensors and transducers inside the plant
converts electrical, physical quantities into
signals, there could be thousand of transmitters
in a factory sending signals to the control system.
These signals are locally processed and converted
into a language that is conversant with the control
systems. Each signal is coded, and a unique tag
is generated for each signal, this completes the
signal generation and transfer up to the control
system process. As the control systems are programmable
and programmed as per the individual process requirement
considering all safe operations and stage interlocks.
Each program is written on the processing and
control unit of PLC, once this activity is completed,
the control system is ready to take charge of
the operations. It now knows what each and every
individual tag means and what shall be the further
process. Also if there is any safety failure or
hazardous activity has taken place it also knows
the corrective action on the same.
