RFID (Radio Frequency Identification) technology is transforming PLC systems by enabling real-time component tracking, quality assurance, and lifecycle management. This article explains how passive RFID tags address key challenges in PLC production, enabling software providers to deliver robust and scalable automation solutions.
RFID Application Scenarios in PLC Manufacturing Systems
1.Component Assembly Tracking
Embed metal-resistant RFID tags on PLC housings to monitor metal parts during assembly.
2.Quality Control & Testing
Attach high-temperature resistant tags to PLC modules to record test results during thermal stress testing.
3.Warehouse & Inventory Management
Use ultra-high frequency (UHF) tags on PLC unit pallets for automated inventory reconciliation.
4.Maintenance & Repair
Store maintenance logs on rewritable high-frequency (HF) tags embedded in PLC units for predictive maintenance.
5.Anti-Counterfeiting
Verify PLC components with encrypted tags to prevent supply chain fraud.
RFID Tag Types and Materials for PLC Manufacturing
1.Passive HF RFID Tags (13.56MHz)
Material: Epoxy or polyimide film.
Key Features:
- Short range (5-20 cm), ideal for secure item-level data collection.
- Resistant to oil, dust, and mild mechanical stress.
Applications:
- Embedded in PLC circuit boards for firmware version tracking.
- Verify calibration data during final testing.
2.Passive UHF RFID Tags (860–960MHz)
Material: PPS (polyphenylene sulfide) or ABS with metal shielding.
Key Features:
- Long range detection (up to 12 meters), ideal for conveyor tracking.
- Works in high temperature environments (up to 150°C).
Applications:
- Tracking PLC units on automated assembly lines.
- Batch scanning of PLC components in a warehousing facility.
3.Specialized tags for industrial needs
Anti-metal tags:
Material: Ferrite substrate or ceramic.
Application: Mounted on metal PLC housing to prevent signal interference.
High-temperature tags:
Material: PEEK (polyetheretherketone).
Application: Withstands reflow soldering process during PCB assembly.
Tamper-proof tags:
Material: Fragile PET with destructible antenna.
Use case: Detect unauthorized access to sensitive PLC components.
Specific Material Benefits and Integration Tips
| Material | Benefits | Best For |
|---|---|---|
| Epoxy Resin | Chemical-resistant, durable | PLC circuit board tagging |
| PPS | High-temperature stability (150°C+) | Solder process tracking |
| Ceramic | Anti-metal, robust | Metal enclosure component tracking |
| Polyimide Film | Thin, flexible | Compact PLC module labeling |
Integration Tips for Software Providers:
Ensure compliance with IEC 61131 and ISO 9001 standards for industrial automation.
For UHF systems, use EPC Gen2 (ISO 18000-6C) for fast batch scanning on production lines.
Highlight encryption protocols such as AES-128 to protect PLC firmware data.
