🛠️ Enhanced Integration Framework

1. Schema Enhancements

Updated core-ia-components-schema-robust.json with:

{
  "binding": {
    "type": {
      "enum": ["property", "expr", "tag", "expr-struct", "query", "tag-history"]
    },
    "transforms": {
      "items": {
        "type": {
          "enum": ["map", "script", "expression", "format"]
        }
      }
    }
  }
}

2. Linter Enhancements

Added comprehensive binding validation:

• Binding Type Validation: Ensures only empirically-validated binding types
• Configuration Validation: Validates required properties per binding type
• Transform Validation: Checks transform types and required properties
• Best Practice Checks: Fallback handling, error handling patterns

3. Agent Integration Tools

CLI Tool (./ignition-lint)

./ignition-lint path/to/view.json --format=json --severity=warning

Returns structured JSON for agent consumption.

Pre-commit Hook

- id: ignition-perspective-lint
  entry: ./ignition-lint
  language: python
  files: '\.json$'

LSP Server (ignition-lsp-server.py)

Real-time binding validation in IDEs.

📋 Binding Validation Rules

Tag Binding Validation

# REQUIRED: tagPath property
if 'tagPath' not in config:
    ERROR: "Tag binding missing required 'tagPath'"

# RECOMMENDED: Fallback handling
if prop_name in critical_props and 'fallbackDelay' not in config:
    INFO: "Consider adding fallback handling"

Expression Binding Validation

# REQUIRED: expression property
if 'expression' not in config:
    ERROR: "Expression binding missing required 'expression'"

Property Binding Validation

# REQUIRED: path property
if 'path' not in config:
    ERROR: "Property binding missing required 'path'"

Transform Validation

# Map transforms
if transform_type == 'map':
    if 'mappings' not in transform:
        WARNING: "Map transform missing 'mappings' array"
    if 'fallback' not in transform:
        INFO: "Consider adding fallback value"

# Script transforms  
if transform_type == 'script' and 'code' not in transform:
    ERROR: "Script transform missing 'code' property"

🎯 AI Development Guidelines

Binding Selection Pattern

def select_binding_type(data_source, complexity):
    if data_source == "static_params":
        return "property"
    elif data_source == "plc_tags":
        return "tag" 
    elif complexity == "simple_calc":
        return "expr"
    elif complexity == "complex_logic":
        return "expr" + "script_transform"

Common Patterns by Usage

Most Common Expression Patterns (47.2% of bindings)

// Conditional logic (most common)
if({[Tank01]Level} > 75, 'HIGH', if({[Tank01]Level} > 25, 'MEDIUM', 'LOW'))

// String concatenation 
'Tank Level: ' + {[Tank01]Level} + '%'

// Quality checking
if({tag.quality} = 'Good', {tag.value}, 'Bad Quality')

Most Common Property Patterns (33.2% of bindings)

{
  "type": "property",
  "config": {
    "path": "view.params.tankId"  // Most common path pattern
  },
  "transforms": [
    {
      "type": "expression", 
      "expression": "'Tank: ' + {value}"  // Common transform
    }
  ]
}

Most Common Tag Patterns (18.6% of bindings)

{
  "type": "tag",
  "config": {
    "tagPath": "[Production]Line01/Tank/Level",
    "mode": "direct",           // Most common mode
    "fallbackDelay": 2.5        // Best practice
  }
}

Transform Usage Guidelines

Use Map Transforms (70.9%) For:

• Status colors: 0 → "#FF0000", 1 → "#00FF00"
• State text: 0 → "Stopped", 1 → "Running"
• Alarm levels: 1 → "Critical", 2 → "Warning"

Use Script Transforms (19.9%) For:

• Complex calculations with multiple inputs
• Mode switching based on screen size
• Integration with external systems
• Custom formatting beyond standard options
