Process mimic diagram design in SCADA systems - Mini Project: Build & Apply

Process Mimic Diagram Design

📖 Scenario: You are working as a SCADA system operator. Your task is to create a simple process mimic diagram that shows the status of three pumps in a water treatment plant. Each pump can be either ON or OFF. The diagram will help operators quickly see which pumps are running.

🎯 Goal: Build a basic process mimic diagram data structure that holds the status of three pumps, add a configuration for the display color based on pump status, update the pump statuses, and finally output the current status of all pumps in a readable format.

📋 What You'll Learn

Create a dictionary called pumps with keys 'Pump1', 'Pump2', and 'Pump3' and initial values 'OFF'.

Create a dictionary called status_colors that maps 'ON' to 'Green' and 'OFF' to 'Red'.

Update pumps so that 'Pump1' and 'Pump3' are set to 'ON'.

Print the status of each pump in the format: Pump1: ON (Green).

💡 Why This Matters

🌍 Real World

Process mimic diagrams are visual tools used in SCADA systems to show the real-time status of equipment like pumps, valves, and sensors. Operators rely on these diagrams to quickly understand system conditions and respond to issues.

💼 Career

Knowing how to represent and update process statuses programmatically is essential for SCADA engineers and operators. It helps in automating monitoring, creating dashboards, and improving plant safety and efficiency.

1

Create initial pump status dictionary

Create a dictionary called pumps with keys 'Pump1', 'Pump2', and 'Pump3' all set to the string 'OFF'.

SCADA systems

# Create the pumps dictionary with all pumps OFF
# Your code here

Need a hint?

Use curly braces {} to create a dictionary and set each pump's value to 'OFF'.

2

Add status color configuration

Create a dictionary called status_colors that maps the string 'ON' to 'Green' and 'OFF' to 'Red'.

SCADA systems

pumps = {'Pump1': 'OFF', 'Pump2': 'OFF', 'Pump3': 'OFF'}
# Create the status_colors dictionary
# Your code here

Need a hint?

Use a dictionary to map each status to its display color.

3

Update pump statuses

Update the pumps dictionary so that 'Pump1' and 'Pump3' have the value 'ON'.

SCADA systems

pumps = {'Pump1': 'OFF', 'Pump2': 'OFF', 'Pump3': 'OFF'}
status_colors = {'ON': 'Green', 'OFF': 'Red'}
# Set Pump1 and Pump3 to ON
# Your code here

Need a hint?

Use dictionary key assignment to change the pump statuses.

4

Display pump statuses with colors

Use a for loop with variables pump and status to iterate over pumps.items(). Inside the loop, print each pump's name, status, and its color from status_colors in the format: Pump1: ON (Green).

SCADA systems

pumps = {'Pump1': 'OFF', 'Pump2': 'OFF', 'Pump3': 'OFF'}
status_colors = {'ON': 'Green', 'OFF': 'Red'}
pumps['Pump1'] = 'ON'
pumps['Pump3'] = 'ON'
# Print pump statuses with colors
# Your code here

Need a hint?

Use an f-string inside the print statement to format the output.
