Schneider Electric Data Types for Conveyor Systems

Implementing Conveyor Systems with Data Types

Conveyor Systems systems in Material Handling require careful consideration of beginner to intermediate control requirements, real-time responsiveness, and robust error handling. This walkthrough demonstrates practical implementation using Schneider Electric EcoStruxure Machine Expert and Data Types programming.

System Requirements:

A typical Conveyor Systems implementation includes:

Input Devices (5 types):
1. Photoelectric sensors: Critical for monitoring system state
2. Proximity sensors: Critical for monitoring system state
3. Encoders: Critical for monitoring system state
4. Weight sensors: Critical for monitoring system state
5. Barcode scanners: Critical for monitoring system state

Output Devices (5 types):
1. AC/DC motors: Controls the physical process
2. Variable frequency drives: Controls the physical process
3. Pneumatic diverters: Controls the physical process
4. Servo motors: Controls the physical process
5. Belt drives: Controls the physical process

Control Logic Requirements:

1. Primary Control: Automated material handling using conveyor belts with PLC control for sorting, routing, and tracking products.
2. Safety Interlocks: Preventing Product tracking
3. Error Recovery: Handling Speed synchronization
4. Performance: Meeting beginner to intermediate timing requirements
5. Advanced Features: Managing Jam detection and recovery

Implementation Steps:

Step 1: Program Structure Setup

In EcoStruxure Machine Expert, organize your Data Types program with clear separation of concerns:

• Input Processing: Scale and filter 5 sensor signals


• Main Control Logic: Implement Conveyor Systems control strategy


• Output Control: Safe actuation of 5 outputs


• Error Handling: Robust fault detection and recovery

Step 2: Input Signal Conditioning

Photoelectric sensors requires proper scaling and filtering. Data Types handles this through memory optimization. Key considerations include:

• Signal range validation


• Noise filtering


• Fault detection (sensor open/short)


• Engineering unit conversion

Step 3: Main Control Implementation

The core Conveyor Systems control logic addresses:

• Sequencing: Managing material transport


• Timing: Using timers for 1-3 weeks operation cycles


• Coordination: Synchronizing 5 actuators


• Interlocks: Preventing Product tracking

Step 4: Output Control and Safety

Safe actuator control in Data Types requires:

• Pre-condition Verification: Checking all safety interlocks before activation


• Gradual Transitions: Ramping AC/DC motors to prevent shock loads


• Failure Detection: Monitoring actuator feedback for failures


• Emergency Shutdown: Rapid safe-state transitions

Step 5: Error Handling and Diagnostics

Robust Conveyor Systems systems include:

• Fault Detection: Identifying Speed synchronization early


• Alarm Generation: Alerting operators to beginner to intermediate conditions


• Graceful Degradation: Maintaining partial functionality during faults


• Diagnostic Logging: Recording events for troubleshooting
