MC Works32 SCADA – Using Local Aliases

In MC Works32 SCADA, local aliases provide a powerful way to simplify complex tags, enhance readability, and streamline project management. By creating these aliases, you can refer to data points, variables, and addresses using shorter, more intuitive names, improving efficiency in larger projects. Below is a guide on setting up and using local aliases effectively in MC Works32 SCADA.

What Are Local Aliases in MC Works32 SCADA?

Local aliases are custom names that act as shorthand references to more complex data points or addresses within MC Works32 SCADA. Instead of repeatedly entering long, complex addresses or tag names, operators can use these aliases to save time and reduce the risk of input errors.

Benefits of Using Local Aliases

• Improves Readability: Shorter names make the project easier to read and understand, especially when working with a large number of tags.
• Simplifies Troubleshooting: When reviewing data or debugging issues, aliases help identify and isolate specific data points quickly.
• Speeds Up Configuration: Using aliases allows faster referencing throughout different sections of the project.

How to Create and Use Local Aliases

To set up and apply local aliases in MC Works32 SCADA, follow these steps:

1. Open the Alias Manager:
   • In the MC Works32 interface, navigate to the section where aliases can be managed. This is usually found in the project configuration or tag management menu.
   • Select Local Alias Manager to begin creating new aliases.
2. Create a New Alias:
   • Click Add New Alias or a similar option, depending on your version of MC Works32.
   • Enter a unique alias name that clearly describes the data point or tag (e.g., Tank1Level, MotorStatus, or TempSetpoint).
   • Link the alias to the appropriate data point or address within your system, ensuring it matches the intended data source.
3. Define Alias Properties:
   • Set the data type for the alias (e.g., integer, float, boolean) based on the data it represents.
   • Optionally, add a description to clarify the alias’s purpose. This is useful for team collaboration and maintenance.
4. Apply the Alias in Your Project:
   • Use the alias name throughout your MC Works32 project instead of the full data address or tag name.
   • Apply aliases in scripting, data displays, alarms, or any configuration where the data point is referenced.

Practical Applications for Local Aliases

Local aliases are versatile and can be applied in various MC Works32 SCADA use cases:

• Screen Displays: Use aliases to label data displays with meaningful names, like FlowRate instead of a complex tag, to enhance operator understanding.
• Scripts and Logic: Simplify scripting by referencing aliases rather than detailed addresses, making scripts easier to read and modify.
• Alarm Management: Reference aliases for alarm triggers, helping to easily identify which data points correspond to specific system events.
• Data Logging and Reports: Use aliases for tag references in data logs and reports, making it clear what each logged value represents.

Best Practices for Creating Local Aliases

• Be Consistent: Use a consistent naming convention for aliases to keep the project organized and understandable.
• Avoid Duplication: Ensure aliases are unique across the project to avoid conflicts or misinterpretations.
• Use Descriptive Names: Choose clear, descriptive names that indicate the data’s purpose or source.

Troubleshooting Tips

• Check Data Type Compatibility: Ensure that the alias’s data type matches the type of data in the linked address.
• Test Alias Functionality: Test each alias in different configurations to confirm that it references the correct data point.
• Update Aliases if Source Changes: If a data address or tag changes, remember to update the corresponding alias to maintain accurate referencing.
