IEC 61131-2 PLC Electrical Safety and EMC Test
The IEC 61131-2 standard is a pivotal document for the design, implementation, and verification of programmable logic controllers (PLCs) used in industrial automation systems. This standard ensures that the electrical safety and electromagnetic compatibility (EMC) aspects are adhered to, thus protecting personnel and equipment from hazards such as electric shock, fire, or interference with other electronic devices.
The IEC 61131-2 standard is divided into several parts, each addressing different aspects of PLC programming. Part 2 specifically covers safety-related parts of control systems, which are critical for ensuring that the system operates safely and reliably. This includes safety requirements for hardware design, software architecture, and human-machine interface (HMI) design.
The testing process involves several steps to ensure compliance with IEC 61131-2:
- Review of the PLC program for adherence to safety-related standards and practices
- Evaluation of hardware design to ensure it meets electrical safety requirements
- Testing of the software, including real-time execution verification and other relevant aspects
- Assessment of the human-machine interface (HMI) for safety features
- Conduction of EMC testing to ensure that the PLC does not interfere with or is not affected by electromagnetic interference
The test parameters and specimen preparation are critical in this process. The specimen, which includes both hardware and software components, must be prepared according to specific guidelines provided in IEC 61131-2. This involves ensuring that all components are properly connected and configured before testing begins.
Instrumentation used during the test can vary but typically includes oscilloscopes for measuring electrical signals, electromagnetic compatibility analyzers for EMC tests, and other specialized equipment necessary to perform the required measurements. The acceptance criteria involve meeting specified limits for electrical safety and EMC as defined in IEC 61131-2.
Reporting of results is comprehensive and detailed, providing a clear picture of the compliance status with respect to both electrical safety and EMC requirements. This includes documentation of all tests conducted, any deviations from standards, and recommendations for corrective actions if necessary.
