Detailed Answer
Safety standard trends: 1. Safety level increase (SIL2/PLd becoming the mainstream requirement); 2. Functional safety certification becoming common (EN ISO 13849/IEC 61508); 3. Cybersecurity requirements (anti-hacking: hopping code + encryption); 4. Operation log mandates (traceability); 5. Human factors standards (anti-accidental operation design). LDER LD series complies with EN ISO 13849; XINGJIA high-end models at SIL2.
