Graphs now use BOTH data-driven initialization (fast when production is running) AND 5-second safety timeout (for idle machine scenarios) + +4. **Multi-Source KPI Calculation** - Calculate KPIs now explicitly handles triggers from both Machine Cycles (continuous) and Scrap Submission (event-based) with proper guards + +5. **Complete Init Node** -

Specify Node-RED Input/Output Requirements +**Example prompt:** +``` +The Machine Cycles function node must have 3 outputs: +- Output 1: DB write message (only when tracking enabled) +- Output 2: State update message (always sent) +- Output 3: KPI trigger message (always sent for continuous updates) + +The return statement should be: +return [dbMsg, stateMsg, kpiTrigger]; +``` + +### 4. Request Defensive Code +**Always ask for:** +- Null/undefined checks before accessing properties +- Type validation for global variables +- Initialization logic at the start of functions +- Error handling for edge cases + +**Example:** +```javascript +// BAD (LLM might generate) +const buffer = global.get("kpiBuffer"); +buffer.push(newValue); + +// GOOD (what you should request) +let buffer = global.get("kpiBuffer"); +if (!buffer || !Array.isArray(buffer)) { + buffer = []; +} +buffer.push(newValue); +global.set("kpiBuffer", buffer); +``` + +### 5. Break Down Complex Changes +**For Phase 3.1 (Continuous KPI Updates), ask in sequence:** +1. "Show me the current return statements in Machine Cycles function" +2. "Modify the function to add a third output for KPI trigger" +3. "Update all return statements to include kpiTrigger message" +4. "Show me how to wire the third output to Calculate KPIs node" + +### 6. Request Testing/Debugging Code +**Ask LLM to include:** +- Debug logging: `node.warn('[KPI] Buffer size: ' + buffer.length);` +- State validation: Check that variables have expected values +- Error messages: Descriptive messages for troubleshooting + +### 7. Validate Against Node-RED Constraints +**Remind LLM of Node-RED specifics:** +- "This is a Node-RED function node, not regular JavaScript" +- "Global context uses global.get/set, not regular variables" +- "The msg object must be returned to send to next node" +- "Use node.warn() for logging, not console.log()" + +### 8. Phase-by-Phase Verification +**After each LLM response:** +1. Verify the code matches the plan +2. Check for initialization logic +3. Confirm output structure matches wiring +4. Ask: "What edge cases does this handle?" + +### 9. Example: Perfect LLM Prompt for Phase 2.1 + +``` +I need to implement KPI throttling with averaging in Node-RED. + +Context: +- Function node: "Record KPI History" +- Input: msg.kpis object with {oee, availability, performance, quality} +- Output: Averaged KPI values sent to Graphs template (or null if not ready to record) + +Global variables needed: +1. kpiBuffer (Array): Accumulates KPI snapshots. Initialize to [] if null. +2. lastKPIRecordTime (Number): Last timestamp when history was recorded. Initialize to (Date.now() - 60000) if null for immediate first recording. + +Requirements: +- Accumulate incoming KPIs in kpiBuffer +- Every 60 seconds (60000ms), calculate average of all buffer values +- Send averaged KPIs to output +- Clear buffer after sending +- If less than 60 seconds since last record, return null (don't send) + +Please write the complete function with: +- Robust initialization (check and set defaults) +- Debug logging (buffer size, time until next record) +- Comments explaining each section +- Edge case handling (empty buffer, first run) +``` + +### 10. Common Pitfalls to Avoid +1. **Assuming LLM knows your flow structure** - Always describe node connections +2. **Not specifying Node-RED context** - LLM might give generic JavaScript instead +3. **Requesting too many changes at once** - Break into single-phase requests +4. **Forgetting to mention global variable persistence** - Specify initialization needs +5. **Not asking for defensive code** - Request null checks and type validation +6. **Vague success criteria** - Define exactly what "working" means + +--- + +--- + +## Quick Reference: Key Code Snippets + +### 1. Init Node (Run on Deploy) +```javascript +// Initialize Global Variables - Inject Once on Deploy +node.warn('[INIT] Initializing global variables'); + +if (!global.get("kpiBuffer")) global.set("kpiBuffer", []); +if (!global.get("lastKPIRecordTime")) global.set("lastKPIRecordTime", Date.now() - 60000); +if (!global.get("lastMachineCycleTime")) global.set("lastMachineCycleTime", Date.now()); +if (!global.get("lastKPIValues")) global.set("lastKPIValues", {}); + +node.warn('[INIT] Complete'); +return msg; +``` + +### 2. Machine Cycles - Add to Final Return +```javascript +// Update last machine cycle time when a successful cycle occurs +if (trackingEnabled && dbMsg) { + global.set("lastMachineCycleTime", Date.now()); +} +return [dbMsg, stateMsg, kpiTrigger]; +``` + +### 3. Calculate KPIs - Multi-Source Guard +```javascript +const trackingEnabled = global.get("trackingEnabled"); +const activeOrder = global.get("activeOrder") || {}; +if (!trackingEnabled || !activeOrder.id) return null; +// ... rest of calculation +``` + +### 4. Work Order START Button - Clear Buffer +```javascript +if (action === "start-tracking") { + global.set("trackingEnabled", true); + global.set("kpiBuffer", []); // Clear stale data + global.set("lastKPIRecordTime", Date.now() - 60000); + // ... send state update +} +``` + +### 5. Graphs Template - Combined Init +```javascript +let chartsInitialized = false; + +scope.$watch('msg', function(msg) { + if (msg && msg.payload && msg.payload.kpis && !chartsInitialized) { + initFilters(); + createCharts(currentRange); + chartsInitialized = true; + } + if (chartsInitialized && msg && msg.payload && msg.payload.kpis) { + updateCharts(msg); + } +}); + +setTimeout(() => { + if (!chartsInitialized) { + initFilters(); + createCharts(currentRange); + chartsInitialized = true; + } +}, 5000); +``` + +--- + +## Final Notes + +1. **Backup First:** Always backup `flows.json` before starting each phase +2. **Test Incrementally:** Don't skip testing between phases +3. **Document Changes:** Note any deviations from plan +4. **Monitor Logs:** Watch Node-RED debug output during testing +5. **Clear Cache:** Browser cache can mask issues +6. **Use LLM Strategically:** Follow the best practices above for precise, working code + +**If you encounter issues not covered in this plan, STOP and ask for help before proceeding.** diff --git a/HOTFIX_MARIADB_ERROR.md b/HOTFIX_MARIADB_ERROR.md new file mode 100644 index 0000000..d39d7fb --- /dev/null +++ b/HOTFIX_MARIADB_ERROR.md @@ -0,0 +1,183 @@ +# Hotfix: MariaDB SQL Syntax Error +## Date: November 27, 2025 + +--- + +## Problem + +When clicking START button on work order, MariaDB error occurred: +``` +You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'machineStatus' at line 1 +``` + +--- + +## Root Cause + +In Phase 3.3 implementation, we added a `stateMsg` object with `topic: "machineStatus"` to track the START/STOP button state.

Refining Global Context Persistence (Roadblock 1) +Your initialization logic is good, but one step can prevent potential data skew on a restart. + +Refinement: Clear Buffer on Production Start. + +The kpiBuffer should be explicitly cleared when the START button is clicked, regardless of the averaging timer. + +Reason: If Node-RED restarts during a long production run (context is restored from disk), the kpiBuffer might contain stale data from before the restart. When the machine cycle flow resumes, new data is added, and the average will be skewed. + +Action: Add a global.set("kpiBuffer", []) into the "Work Order buttons" logic right after global.set("trackingEnabled", true) (Phase 3.3 Backend Update). This resets the history buffer cleanly for the new run. + +2. Refining the Availability Logic (Roadblock 5) +The Time-Based Availability is much better, but it relies on a new variable. + +Refinement: Consolidate State for lastMachineCycleTime. + +You are introducing global.get("lastMachineCycleTime"). Ensure this value is written only inside the Machine Cycles function, and only when a successful cycle is detected. This separates the machine's "pulse" from the general KPI calculation trigger. + +Action: Add the following to the Machine Cycles function right before the final return statement: + +JavaScript + +if (trackingEnabled && dbMsg) { // dbMsg implies a cycle occurred + global.set("lastMachineCycleTime", Date.now()); +} +Initial Value: Ensure that global.get("lastMachineCycleTime") is initialized to Date.now() on startup/deploy (Roadblock 1's Init Node) to prevent an immediate 0% availability on a fresh deploy. + +3. Refining UI Initialization (Roadblock 3 - Option A) +Your data-driven initialization (Option A) is the strongest choice, but needs a safe fallback. + +Refinement: Combine Data-Driven with Guaranteed Timeout. + +If no production is running, no KPI messages flow, and the charts will never initialize. + +Action: Keep Option A (data-driven) but wrap the scope.$watch in an initial setTimeout (e.g., 5 seconds) that only initializes the charts if the chartsInitialized flag is still false. This covers the "dashboard loaded, but machine is idle" scenario. + +JavaScript + +// In Graphs Template (Simplified logic) +// ... scope.$watch logic (Option A) ... + +// ADDED: Safety timer for when machine is idle +setTimeout(() => { + if (!chartsInitialized) { + node.warn("Charts initialized via safety timer (machine idle)."); + initFilters(); + createCharts(currentRange); + chartsInitialized = true; + } +}, 5000); // 5 seconds grace period +4. Minor Flow/Dependency Note +Clarity: Ensure the Calculate KPIs function (Phase 3.2) correctly handles the fact that it is now triggered by two sources: + +Machine Cycles (Continuous/Real-Time) + +Scrap Submission (Event-based) + +The logic should execute regardless of the input message's content, as long as it receives a trigger, ensuring the availability calculation runs in both continuous and event-driven scenarios.

About this Dashboard

\n

This interface centralizes Overall Equipment Effectiveness metrics, real-time production details, and critical status indicators. Each tab follows a unified layout so operators can scan performance, alerts, and configuration without relearning navigation.

\n
\n\n
\n

How to Start / Stop Production

\n

Navigate to the Work Orders tab, select the required job, and use the primary controls to begin or end production. Always log the reason for stoppages using the Alerts tab, and confirm machine readiness before resuming. Follow your facility’s standard operating procedure for approvals and sign-off.

About this Dashboard

\n

This interface centralizes Overall Equipment Effectiveness metrics, real-time production details, and critical status indicators. Each tab follows a unified layout so operators can scan performance, alerts, and configuration without relearning navigation.

\n
\n\n
\n

How to Start / Stop Production

\n

Navigate to the Work Orders tab, select the required job, and use the primary controls to begin or end production. Always log the reason for stoppages using the Alerts tab, and confirm machine readiness before resuming. Follow your facility’s standard operating procedure for approvals and sign-off.

About this Dashboard

\n

This interface centralizes Overall Equipment Effectiveness metrics, real-time production details, and critical status indicators. Each tab follows a unified layout so operators can scan performance, alerts, and configuration without relearning navigation.

\n
\n\n
\n

How to Start / Stop Production

\n

Navigate to the Work Orders tab, select the required job, and use the primary controls to begin or end production. Always log the reason for stoppages using the Alerts tab, and confirm machine readiness before resuming. Follow your facility’s standard operating procedure for approvals and sign-off.

About this Dashboard

\n

This interface centralizes Overall Equipment Effectiveness metrics, real-time production details, and critical status indicators. Each tab follows a unified layout so operators can scan performance, alerts, and configuration without relearning navigation.

\n
\n\n
\n

How to Start / Stop Production

\n

Navigate to the Work Orders tab, select the required job, and use the primary controls to begin or end production. Always log the reason for stoppages using the Alerts tab, and confirm machine readiness before resuming. Follow your facility’s standard operating procedure for approvals and sign-off.

About this Dashboard

\n

This interface tracks Overall Equipment Effectiveness metrics, production progress, and incident logging for injection molding operations. Navigate between tabs using the sidebar to access work orders, real-time monitoring, performance graphs, incident reporting, and machine configuration.

\n
\n\n
\n

Getting Started with a Work Order

\n

Go to the Work Orders tab and upload an Excel file with your work orders, or select from existing orders in the table. Click Load to activate a work order, then navigate to the Home tab where you'll see the current work order details. Before starting production, configure your mold settings in the Settings tab by selecting a mold preset or entering cavity counts manually.

\n
\n\n
\n

Running Production

\n

On the Home tab, press the START button to begin production. The system tracks cycle counts, good parts, scrap, and progress toward your target quantity. Press STOP to pause production. Monitor real-time KPIs including OEE, Availability, Performance, and Quality metrics displayed on the dashboard.

\n
\n\n
\n

Logging Incidents

\n

Use the Alerts tab to record production incidents. Quick-log common issues with preset buttons like Material Out, Machine Stopped, or Emergency Stop. For detailed logging, select an alert type from the dropdown, add notes, and submit. All incidents are timestamped and contribute to availability and OEE calculations.

\n
\n\n
\n

Configuring Molds

\n

In the Settings tab, use the Mold Presets section to search for your mold by manufacturer and name. Select a preset to automatically load cavity counts, or manually adjust the Mold Configuration fields below. If your mold isn't available, use the Add Mold button in the Integrations section to create a new preset with manufacturer, name, and cavity details.

\n
\n\n
\n

Viewing Performance Data

\n

The Graphs tab displays historical OEE trends broken down by Availability, Performance, and Quality. Use these charts to identify patterns, track improvements, and diagnose recurring issues affecting your production efficiency.

About this Dashboard

\n

This interface tracks Overall Equipment Effectiveness metrics, production progress, and incident logging for injection molding operations. Navigate between tabs using the sidebar to access work orders, real-time monitoring, performance graphs, incident reporting, and machine configuration.

\n
\n\n
\n

Getting Started with a Work Order

\n

Go to the Work Orders tab and upload an Excel file with your work orders, or select from existing orders in the table. Click Load to activate a work order, then navigate to the Home tab where you'll see the current work order details. Before starting production, configure your mold settings in the Settings tab by selecting a mold preset or entering cavity counts manually.

\n
\n\n
\n

Running Production

\n

On the Home tab, press the START button to begin production. The system tracks cycle counts, good parts, scrap, and progress toward your target quantity. Press STOP to pause production. Monitor real-time KPIs including OEE, Availability, Performance, and Quality metrics displayed on the dashboard.

\n
\n\n
\n

Logging Incidents

\n

Use the Alerts tab to record production incidents. Quick-log common issues with preset buttons like Material Out, Machine Stopped, or Emergency Stop. For detailed logging, select an alert type from the dropdown, add notes, and submit. All incidents are timestamped and contribute to availability and OEE calculations.

\n
\n\n
\n

Configuring Molds

\n

In the Settings tab, use the Mold Presets section to search for your mold by manufacturer and name. Select a preset to automatically load cavity counts, or manually adjust the Mold Configuration fields below. If your mold isn't available, use the Add Mold button in the Integrations section to create a new preset with manufacturer, name, and cavity details.

\n
\n\n
\n

Viewing Performance Data

\n

The Graphs tab displays historical OEE trends broken down by Availability, Performance, and Quality. Use these charts to identify patterns, track improvements, and diagnose recurring issues affecting your production efficiency.

About this Dashboard

\n

This interface tracks Overall Equipment Effectiveness metrics, production progress, and incident logging for injection molding operations. Navigate between tabs using the sidebar to access work orders, real-time monitoring, performance graphs, incident reporting, and machine configuration.

\n
\n\n
\n

Getting Started with a Work Order

\n

Go to the Work Orders tab and upload an Excel file with your work orders, or select from existing orders in the table. Click Load to activate a work order, then navigate to the Home tab where you'll see the current work order details. Before starting production, configure your mold settings in the Settings tab by selecting a mold preset or entering cavity counts manually.

\n
\n\n
\n

Running Production

\n

On the Home tab, press the START button to begin production. The system tracks cycle counts, good parts, scrap, and progress toward your target quantity. Press STOP to pause production. Monitor real-time KPIs including OEE, Availability, Performance, and Quality metrics displayed on the dashboard.

\n
\n\n
\n

Logging Incidents

\n

Use the Alerts tab to record production incidents. Quick-log common issues with preset buttons like Material Out, Machine Stopped, or Emergency Stop. For detailed logging, select an alert type from the dropdown, add notes, and submit. All incidents are timestamped and contribute to availability and OEE calculations.

\n
\n\n
\n

Configuring Molds

\n

In the Settings tab, use the Mold Presets section to search for your mold by manufacturer and name. Select a preset to automatically load cavity counts, or manually adjust the Mold Configuration fields below. If your mold isn't available, use the Add Mold button in the Integrations section to create a new preset with manufacturer, name, and cavity details.

\n
\n\n
\n

Viewing Performance Data

\n

The Graphs tab displays historical OEE trends broken down by Availability, Performance, and Quality. Use these charts to identify patterns, track improvements, and diagnose recurring issues affecting your production efficiency.

About this Dashboard

\n

This interface centralizes Overall Equipment Effectiveness metrics, real-time production details, and critical status indicators. Each tab follows a unified layout so operators can scan performance, alerts, and configuration without relearning navigation.

\n
\n\n
\n

How to Start / Stop Production

\n

Navigate to the Work Orders tab, select the required job, and use the primary controls to begin or end production. Always log the reason for stoppages using the Alerts tab, and confirm machine readiness before resuming. Follow your facility\u2019s standard operating procedure for approvals and sign-off.

About this Dashboard

\n

This interface centralizes Overall Equipment Effectiveness metrics, real-time production details, and critical status indicators. Each tab follows a unified layout so operators can scan performance, alerts, and configuration without relearning navigation.

\n
\n\n
\n

How to Start / Stop Production

\n

Navigate to the Work Orders tab, select the required job, and use the primary controls to begin or end production. Always log the reason for stoppages using the Alerts tab, and confirm machine readiness before resuming. Follow your facility\u2019s standard operating procedure for approvals and sign-off.
