What is an industrial control system?

An industrial control system (ICS) automates industrial processes using interconnected instruments and control systems. ICSs are essential in industries like manufacturing, aviation, communications, and energy.

Types of ICSs:

• Distributed Control Systems (DCS): Centralised control over processes across multiple locations.
• Building Management Systems (BMS): Manages HVAC, lighting, and security in buildings.
• Safety Instrumented Systems (SIS): Ensures safe industrial operations.

How does an industrial control system work?

1. Sensors and switches measure variables.
2. Data is sent to a controller.
3. The controller processes signals and executes tasks.
4. Actuators or valves adjust based on setpoints.

Key challenges faced by industrial control systems companies

Industrial control systems companies must navigate a complex landscape where security, flexibility, sustainability, and profitability are equally critical. As ICSs become more interconnected, the risk of cyber threats increases, demanding robust security measures without compromising operational efficiency.
