This document discusses using a programmable logic controller (PLC) and supervisory control and data acquisition (SCADA) system to control an asphalt batch mixing plant. A PLC takes input from sensors, performs logic functions, and outputs to actuators to control devices. A SCADA system provides supervisor-level control, displays graphs and faults, stores data, and has graphical interfaces. The system has advantages like improved safety, environmental friendliness, low maintenance costs, and fuel efficiency. Its disadvantages include needing skilled labor and higher costs.

1. Asphalt Batch Mixing Plant using
PLC & SCADA

2.  The purpose of this project is to present a
programmable logic controller (PLC) based
control system that is applied to the manufacture
of asphalt other forms of coated road stone,
sometimes collectively known as blacktop.
 Asphalt Batch mixing and load out plant typically
use a combination of SCADA and Programmable
Logic Controllers to achieve this.

6.  The S7-1214 controller provides the flexibility
and power to control a wide variety of devices
in support of your automation needs.

7. SCADA:
 Supervisor level control.
 Represent graph.
 Represent the fault of process.
 Used in data storage.
 Represent graphical.

8. Advantages:
• Human safety.
• Environmentally friendly.
• Very low maintenance cost due to the design
concept.
• Economical fuel consumption due to highly
efficient burning, and reduced heat losses in
conduction.
• Ability to burn any fuel.
• Reliability, high performance level and low
maintenance costs as a result of high quality
components.

9. Disadvantages:
• Skills of man power.
• High cost.
