Interface Components

The Runtime Diagnostics interface consists of three main elements:

1. Module Status

Control panel with command buttons to Start, Stop, or Pause execution of any module.

2. Run Tools

Launch additional diagnostic tools:

• Property Watch
• Trace Window
• Module Information
• Performance Test

3. Runtime Connection State and Synchronization

Shows runtime connection status and whether Designer configuration is synchronized with runtime configuration in memory.

Configuration-Runtime Synchronization

Offline Configuration

In Offline Configuration mode, saved changes only update to runtime if Hot Update is used. Otherwise, changes take effect at next solution start. This mode is useful when you want to make multiple changes without immediately affecting the running system.

Online Configuration

With Designer connected to Runtime and online configuration enabled, all modifications apply immediately as you edit tables or save documents.

Limitations: Some operations cannot be applied online:

• Tag type modifications
• Client-Server domain changes for scripts
• Major structural changes requiring compilation

These changes take effect at next system initialization.

Synchronization Status

The synchronization table shows if configuration file matches running solution. Common mismatch scenarios:

Hot Reload Command

Hot Reload applies updated configuration to runtime without shutdown, preserving tag values and objects in memory.

Process:

1. Identifies all modified objects (listed in synchronization table)
2. Briefly pauses affected modules
3. Applies changes to loaded modules
4. Resumes execution

Property Watch

Tool designed to access and modify system tags and internal properties with IntelliSense support.

Interface Elements

Usage

Object Selection:

• Type object name in Object column
• Use IntelliSense (type "tag." for suggestions)
• Select from browser tab
• Build custom monitoring list

Value Modification:

• Select property
• Enter new value (if permitted)
• Changes apply immediately

Module Control:

• Start/stop individual modules
• Monitor module status
• Test configuration changes

Trace Window

System message display tool providing status information about system operations.

Interface Elements

Settings Configuration

Message Types:

• Info: User notices and status
• Error: Operation failures
• Debug: Developer information
• Warning: Potential issues

Module Selection: Choose specific modules to monitor for targeted diagnostics.

Output Options:

• Grid: Display in Trace Window
• File: Export to log file

Object Monitoring:

1. Enter object name in field
2. Select property from list
3. Click "Add" to monitor
4. Changes trigger trace messages

Device Communication

Common use for finding device information:

• Read/write status
• TX frames (sent)
• RX frames (received)
• Invalid addresses (ControlLogix)

Note: For Devices, enable only error, info, and warning. Debug creates excessive data.

CallStack Display: Enable Debug in Settings and Debug Information in Runtime → Build and Publish.

Module Information

Provides detailed operation information for all modules, including communication channels, reading groups, and error reports.

Module Types

Device Module Diagnostics

Read Groups Information:

• Virtual reading groups
• Runtime per item
• Successful/failed reads
• Error codes and timestamps

Troubleshooting Steps:

1. Check Read Groups Information for communication blocks
2. Systematic errors indicate access issues - verify node address
3. Block-specific errors - check tags and addresses
4. Use Trace Window for detailed error information
5. OPC discarded items show wrong addresses

Controls

Performance Test

Diagnostic feature to measure system performance through intensive resource usage simulation.

Access: Runtime → Diagnostics → Run Tools → Performance Test

Test Methodology

The test executes memory-intensive operations:

csharp

DateTime t = DateTime.Now;
for (int x = 0; x < 100; x++)
{
    int size = 1024 * 1024;
    int[] memAlloc = new int[size];
    for (int i = 0; i < size; i++)
    {  
        memAlloc[i] = i;
    }
}
result = DateTime.Now - t;

Performance Benchmarks

Virtual Machine Note: VM configuration significantly impacts performance. Adjust VM settings if results are inadequate.

Synchronization Table Columns

Launching Diagnostic Tools

Three methods to open diagnostic tools:

1. Startup Window (Server side)
   • Shows module status
   • Launch buttons for each tool
   • Tools run in separate windows
2. Runtime Diagnostics Page
   • Designer → Runtime → Diagnostics
   • Run Tools section
3. Client Side
   • Available from client applications
   • Remote diagnostics capability

Note: Tools may minimize to taskbar when launched.

Best Practices

Online Configuration

• Enable for real-time testing
• Monitor synchronization status
• Use Hot Reload for safe updates
• Test one module at a time

Troubleshooting

• Start with Module Information for overview
• Use Trace Window for detailed errors
• Property Watch for specific values
• Performance Test for system capability

Enterprise Test Mode

System only reads from field devices in test mode, even with write configuration present.
