PLC applications are extensively used in
industries to control and facilitate repetitive
processes such as manufacturing cell
management, fly-by-wire control, or nuclear
plant systems.
One of these applications is industrial
automation which includes numerous
automated processes. This again
includes boiler automation which
demands determination of certain
physical parameters (e.g. pressure,
temperature, etc.) & utilizing these
parameters to make the boiler start-stop or
function in any manner we want, but
automatically, without involvement of any
human.
Steam boilers are used to produce
saturated or superheated steam which are
then used in different processes like the
superheated steam is used to run the
turbines which in turn produces electricity.
Historically steam boilers were used in
trains to run the steam engines, steam is
also used in chiller of central cooling
system which helps in maintaining the
chemical soft inside the chiller or otherwise
it will get harder and the chiller will not
work, it is also used in re-boiling operations
and cooking and there are a lot more
functions of steam boilers.

Liquid Level Sensor
Most of the sensor placed inside the water
cause electrolytic reaction between liquid
and sensor causing loss of effectiveness.
One solution to this problem is to ensure
an AC potential rather than DC potential
between the electrodes.
Capacitors, a NAND gate IC and relay is
used to construct the level meter.
Temperature Sensor
A platinum resistance temperature detector
(RTD) Pt100 is a device with a typical
resistance of 100 at 0C (it is called
Pt100). It changes resistance value as its
temperature changes following a positive
slope (resistance increases when
temperature is increasing).
Pressure Sensor
FST800-211 is used as a pressure sensor.
The pressure sensor can measure 3-5 psi.
Solenoid ValveA solenoid valve is an Electromechanically
operated valve. The valve is controlled by
an electric current through the solenoid.
The solenoid valve controls the water input
in boiler. The solenoid valve can be
controlled through the PC based HMI.
The valve is operated at 220v AC.
PLC (Delta DVP14SS211-R)
ModBus Protocol
Modbus is a serial communicat
protocol originally published by Mod
(now Schneider Electric) in 1979 for
with its programmable logic contro
(PLCs). Simple and robust, it has s
become a de facto standard communica
protocol, and it is now a comm
available means of connecting indus
electronic devices.
PLC HMI
National Instruments LABView 2011 is u
to construct the HMI. Also NIs OPC Seis used to setup communication betw
HMI and PLC. Inputs, outputs, sp
registers and data registers are acces
by using Tags specified in the OPC serv
