1. Start Runtime in Development Mode

Quick Test from Designer

1. Open MyFirstSolution in Designer (if not already open)
2. Go to Runtime → Startup
3. Make sure that under "ExecutionProfile" the option Development is checked
4. Observe startup sequence:
   • TServer Startup...
   • Process starting...
   • Connecting to server...
   • Server Started Successfully
   • Starting modules...

Stop Runtime

• Click Stop button in the Designer → Runtime → Startup
• Wait for clean shutdown
• Once the shutdown is complete, the "Run Startup" button will be available again

2. Explore Execution Profiles

View Available Profiles

1. Go to Runtime → Execution Profiles
2. See three default profiles:
   • Development 
   • Validation 
   • Custom

3. Monitor Runtime Status

Start Full Runtime

1. Go to Runtime → Startup
2. Ensure Development profile selected
3. Click Run Startup
4. Watch startup progress

Check Module Status

On the TStartup display, observe which modules are running:

, paused or stopped.

Monitor Resources

Note the real-time metrics:

• Memory Usage: ~50-100 MB (typical)
• CPU: < 5% (idle)
• Uptime: Counting from startup
• Connected Clients: 0 (none yet)

4. Use Property Watch

Open Property Watch

1. Click Runtime → Runtime Diagnostics
2. Select Property Watch
3. New window opens

Browse Runtime Objects

Navigate the object tree:

1. Expand Tag node
2. Find your tags (Tag1Double1, Tag2Double2, Tag3Double3)Double
3. -click Tag1Click Double1
4. View properties:
   • Value: Current value
   • Quality: 192 (Good/Bad)
   • Timestamp: Last update

Modify a Value

Test runtime write:

1. Select Tag1.Double1 Value
2. Enter new value: 50
3. Press Enter
4. Observe value changes
5. Note timestamp updates

Make a Change in Designer

While runtime is running:

1. Return to Designer (keep runtime active)
2. Go to Unified Namespace → Tags
3. Add a new tag: Tag4
4. Set Type: Double
5. Save (Ctrl+S)

Apply Without Stopping

1. Click Apply Online Changes button
2. Dialog shows pending changes:
   • "Added: Tag4"
3. Click Apply
4. Message: "Changes applied successfully"

Verify in Property Watch

1. Return to Property Watch
2. Click Refresh
3. Expand Tag node
4. Confirm Tag4 appears
5. Runtime never stopped!

. Test Client Connections

Enable Web Client

1. Go to Runtime → Startup
2. Note the Web HTMNL5 Client URL: http://localhost/MyFirstSolution127.0.0.1:3201/html5
3. Click the link play button or copy to browser

Access Web Interface

In your browser:

1. Page loads automatically
2. If prompted for login:
   • Username: Administrator
   • Password: (blank for development)
3. Main display appears

Test Display Updates

1. Return to Property Watch
2. Change Tag1 Double1 value to 75
3. Watch web display update in real-time
4. Confirms client-server communication

6. Use Trace Window

Open Trace Window

1. Click Runtime → Runtime Diagnostics
2. Select Trace Window

Configure Trace Level

Set diagnostic detail:

1. Select Level: Info
2. Check modules to monitor:
   • ? TServer
   • ? Device
   • ? Scripts

Generate Trace Messages

1. In Property Watch, change a tag value
2. Observe trace messages:

   [Info] Tag.Tag1 value changed: 50 -> 75
   [Info] Client connection from 127.0.0.1
   [Info] Display refresh requested

Export Trace Log

• Click Export button
• Save as: MyFirstSolution_trace.log
• Useful for troubleshooting

8. Stop and Restart Runtime (2 min)

Graceful Shutdown

1. Go to Runtime → Startup
2. Click Stop Runtime
3. Confirm when prompted
4. Watch shutdown sequence:

   [00:01] Stopping client connections...
   [00:02] Closing modules...
   [00:03] Saving data...
   [00:04] Runtime stopped

Quick Restart

Test restart capability:

1. Click Run Startup again
2. Solution restarts with Development profile
3. Previous tag values retained (if configured)
4. Clients auto-reconnect

Final Shutdown

• Click Stop Runtime
• Close diagnostic windows
• Runtime exercises complete

Key Takeaways

You've learned to:

• Start runtime in test and full modes
• Understand execution profiles for different environments
• Monitor runtime status and module health
• Use Property Watch for real-time tag monitoring
• Apply changes without stopping execution
• Connect and test client displays
• Use Trace Window for diagnostics
• Properly stop and restart runtime

Productivity Tips Discovered

• F5 for quick test mode
• Online changes prevent downtime
• Property Watch for live debugging
• Trace levels control diagnostic detail
• Profiles separate dev/test/production

Troubleshooting

Runtime won't start?

• Check license is valid for runtime
• Verify no other instance running
• Look for port conflicts (10397)
• Check Windows Event Log

Modules show error state?

• Review module configuration
• Check Trace Window for errors
• Verify database connections
• Ensure proper permissions

Can't apply online changes?

• Some changes require restart
• Check if production profile (protected)
• Verify user has permission
• Save changes before applying

Client can't connect?

• Check firewall allows connection
• Verify URL is correct
• Ensure runtime is running
• Test with localhost first

High CPU or memory usage?

• Check script execution frequency
• Review device communication rates
• Look for infinite loops in scripts
• Monitor historian storage settings

1. Click Settings
2. Check Debug
