Process Modules (Connect & Collect)

Overview

Process Modules form the industrial integration layer of FrameworX, connecting your solution to the physical world. These modules handle all aspects of field device communication, event detection and management, and time-series data collection. Working together, they collect raw data from your process, monitor conditions, generate notifications, and store historical records - providing the real-time and historical data foundation for your industrial application.

Where Process Modules Fit

Process Modules bridge the gap between field equipment and your application:

• Connect to - PLCs, RTUs, sensors, and industrial equipment
• Collect from - Real-time process values and equipment status
• Monitor for - Alarm conditions and critical events
• Store in - Time-series databases for trending and analysis
• Feed to - Application logic and user interfaces

Integration Patterns

Pattern 1: SCADA Collection

Typical SCADA data collection setup:

Field Devices → Channels → Nodes → Points → Tags
     ↓              ↓         ↓        ↓        ↓
   PLCs        Protocols  Devices  Mapping  Values
                                              ↓
                                     Alarms & Historian

Pattern 2: Redundant Communication

High-availability configuration:

• Primary channel with main network path
• Backup channel with alternate path
• Automatic failover on communication loss
• Synchronized data between paths

Pattern 3: Multi-Rate Collection

• Normal (1s) - Process variables
• Slow (10s) - Status information
• On-Demand - Configuration data

Pattern 4: Event-Driven Architecture

Minimize polling with events:

• Unsolicited messages from devices

Module Dependencies

Data Flow Dependencies

Devices → Tags (Write values)
Tags → Alarms (Monitor conditions)
Tags → Historian (Store values)
Alarms → Notification (Send alerts)
All → Displays (Visualization)

Configuration Dependencies

• Tags must exist before point mapping
• Storage locations before historian tables
• Alarm groups before alarm items
• Channels before nodes
• Nodes before points
