Process automation is viewed as inevitable in modern industrial manufacturing. It involves monitoring and controlling field devices, systems, and processes across a large number of industries.
The lack of understanding about automation and the misconceptions about cost of adopting automation are the two main challenges faced by businesses, particularly in SMEs. It is important for stake holders to identify and check how adaptable an automation is for a process.
Here are some points to help you understand more about automation in process control:
- Advantages
- Types of Control Systems
- Structure of an Industrial Control System

Open Loop
- Also known as a non-feedback control system
- No automatic correction of the variation in its output
- Takes input under the consideration and doesn’t react on the feedback to obtain the output
- The changes in output can be corrected only by changing the input manually
- Simple in construction and cheaper
Closed Loop
- Also known as a feedback control system
- Considers the current output and alters it to the desired condition. The control action is based on the output
- Takes into account the disturbances also and makes the corrective action
- Accurate, stable and less affected by noise
- Complex and costlier to implement
Common keywords:
HMI (Human Machine Interface) is a user interface or dashboard that connects a person to a machine, system, or device.
SCADA (Supervisory Control and Data Acquisition) is a control system architecture that uses computers, networked data communications and graphical user interfaces for high-level process supervisory management; and uses other devices such as programmable logic controller (PLC) to interface with the process plant or field devices.
PLC (Programmable Logic Controllers) is an industrial digital computer which has been ruggedized and uses stored instructions in a programmable memory to implement logic, sequencing, timing, counting, and arithmetic control functions for controlling field devices and processes.
RTU (Remote Terminal Units) is a microprocessor-based device that monitors and controls field devices, that then connects to a control system or SCADA (supervisory control and data acquisition) systems.
