Discover best practices for AVEVA Plant SCADA (formerly CitectSCADA) to improve system performance, security, and usability for industrial operations
AVEVA Plant SCADA, formerly known as CitectSCADA, is a powerful industrial control and monitoring system trusted in manufacturing, utilities, and infrastructure worldwide. A well-designed SCADA system not only ensures smooth day-to-day operations but also reduces downtime, improves safety, and supports long-term scalability
In this guide, we share 7 essential tips for engineers and system integrators to get the most out of their Plant SCADA implementation
1. Understand the Architecture
Knowing how your system works at a fundamental level helps in both design and troubleshooting.
- Learn the role of I/O Servers, Clients, Alarms, Trends, and Reports.
- Understand how SCADA nodes communicate and synchronize data
- Familiarize yourself with Cicode scripting — the core automation language in Plant SCADA.
Example: If a trend page is slow to update, knowing the exact data path (PLC → I/O Server → Client) helps you pinpoint the problem faster.
2. Keep Systems Modular
- Modular designs are easier to maintain, update, and scale.
- Use equipment templates for common assets (motors, pumps, valves).
- Apply genies/template objects to reduce engineering time.
- Organize assets with Equipment Hierarchy for structured navigation.
Pro Tip: A modular motor template can be reused in dozens of places with only a tag name change.
3. Use a Clear Tag Naming Convention
- A logical tag structure makes your system easier to read, troubleshoot, and integrate.
- Use a hierarchy: Plant.Area.Equipment.Parameter (e.g., Plant1.Tank2.Level).
- Avoid unclear abbreviations.
- Document and enforce naming rules across your project.
Mistake to Avoid: Mixing dots, underscores, or inconsistent capitalization in tag names can break scripts and cause search issues.
4. Apply Security Best Practices
SCADA systems control critical infrastructure — security must be a priority.
- Implement role-based access with minimal privileges
- Change default passwords immediately
- Enable user action logging and regularly review audit trails.
Example: Being able to trace an unexpected valve opening to a specific operator account increases accountability.
5. Write Clean, Efficient Cicode
- Good Cicode practices reduce errors and improve system performance
- Keep code modular, well-commented, and easy to read
- Avoid excessive sleep or delay — use events and triggers
- Test in simulation before going live
6. Manage Alarms Effectively
Poor alarm handling can overwhelm operators and mask real problems.
- Prioritize alarms by severity and importance
- Use suppression, shelving, and delays to filter nuisance alarms
- Group alarms logically for better operator awareness.
Example: Instead of generating multiple low-pressure alarms for each pump, configure a single ‘Low System Pressure’ alarm.
7. Create Efficient, User-Friendly Graphics
Clear graphics improve operator decision-making
- Avoid clutter — show only what’s needed
- Use color coding to indicate states (green = running, red = stopped)
- Optimize graphics for thin client performance
By following these best practices, engineers and integrators can design Plant SCADA systems that are efficient, secure, and future-ready. But to truly master implementation, optimization, and troubleshooting, nothing beats hands-on training with experts.
