• Interactive presentations with system screenshots and functional diagrams.
• Group activities simulating a control room scenario and interpreting an HMI screen.
• Individual exercises on navigating a simulated SCADA environment and locating key assets.
• Discussions on the differences between manual, local, and remote control.
• Case studies of incidents caused by operator error or misinterpretation of data.

Unit 1: What is SCADA?

• The purpose and scope of **Supervisory Control and Data Acquisition**
• SCADA's role in the ISA-95/Purdue model of industrial networks
• Understanding the "Supervisory" function versus direct control
• Key application areas: Water, Power, Pipelines, and Manufacturing

• Overview of the five main layers of a SCADA system
• The function of the central **SCADA Server** and its services

Unit 2: Field Devices and Data Flow

• The difference between **PLCs (Programmable Logic Controllers)** and **RTUs (Remote Terminal Units)**
• Understanding digital and analog signals (ON/OFF vs. continuous values)
• Introduction to basic sensor and actuator types

• How field data (e.g., pressure, temperature) is collected and sent to the HMI
• The concept of a "poll cycle" and communication time delays

Unit 3: The Operator Interface (HMI)

• The role of the **Human-Machine Interface (HMI)** in visualization
• Navigating typical plant displays and process graphics safely
• Interacting with controls: setpoints, valve commands, and pump starts

• How to locate and interpret historical trends and real-time data displays
• Understanding the importance of reliable time stamping in the system

Unit 4: Alarms and Basic Operational Response

• Defining an alarm, a warning, and a system event
• Understanding alarm priority levels (e.g., Critical, High, Low)
• The correct procedure for **acknowledging and clearing alarms**
• Consequences of ignoring or suppressing alarms without authorization

• Following standard operating procedures (SOPs) based on HMI status
• The process for safely requesting and taking a device out of service

Unit 5: Safety and System Integrity

• Understanding the relationship between SCADA and **Safety Instrumented Systems (SIS)**
• Recognizing security alerts and reporting suspicious system activity
• Importance of maintaining a secure physical environment for control equipment
• Following correct login and access control protocols
