ScadaBR vs. Commercial SCADA: Cost, Features, and Use Cases

Advanced ScadaBR Tips: Scripting, Alarms, and Custom Dashboards

Use Mango/ScadaBR scripting modules: Prefer the built-in scripting environment (JavaScript/Groovy depending on version) for data transformations, custom calculations, and event-driven actions.
Keep scripts modular: Break complex logic into reusable functions and comment intent clearly.
Optimize for performance: Avoid heavy loops on main threads; use data point queries with time ranges instead of per-sample retrieval when possible.
Error handling & logging: Catch exceptions, log useful context (point ID, timestamps), and avoid exposing sensitive info in logs.
Testing: Validate scripts on a staging system or small data set. Use dry-run flags or simulated inputs where available.
Security: Restrict script permissions, avoid executing arbitrary external commands, and sanitize inputs from external sources.

Design clear alarm tiers: Use severity levels (Info, Warning, Critical) and distinct actions for each (notify, call script, trigger relay).
Avoid alarm flooding: Implement hysteresis, debounce, or minimum duration conditions to prevent repeated triggers from noisy signals.
Use composite conditions: Combine point states and time-of-day or production-state conditions to reduce false positives.
Notifications: Configure multi-channel notifications (email, SMS, webhooks) with templated messages containing point name, value, timestamp, and recommended action.
Acknowledgement workflow: Require user acknowledgement for critical alarms and track who acknowledged and when.
Historical context: Store alarm history with associated sample windows and related point values to simplify root-cause analysis.

Layout for clarity: Prioritize critical KPIs at the top-left; group related controls and indicators; use consistent colors for states.
Use widgets effectively: Combine trend charts, numeric displays, binary indicators, and control buttons. Prefer aggregated charts (min/max/avg) for longer time spans.
Responsive design: Make pages accessible on different screen sizes — use multiple dashboard variants if needed (desktop vs mobile).
Real-time vs historical: Separate live-monitoring panels from historical-analysis panels to reduce update frequency on heavy views.
User roles & permissions: Restrict control widgets to authorized users and offer read-only variants for operators or external stakeholders.
Performance tuning: Limit the number of live-bound widgets per page, use server-side aggregation, and set reasonable refresh intervals.
Custom themes & branding: Use CSS/skin features to align dashboards with company branding while keeping contrast and accessibility in mind.

Monitor temperature point with threshold 80°C.
On first breach for >2 minutes → create Warning alarm and send email.
If breach persists >10 minutes → escalate to Critical, send SMS and trigger audible alert.
On return-to-normal → auto-clear Warning; require manual acknowledgement to clear Critical.
