常见问题解答

关于工业自动化、协议和产品选择的常见问题

What is the best protocol for industrial automation communication?
The best protocol depends on your application. Modbus RTU/TCP remains the most widely deployed for device-level communication. For IT/OT convergence and enterprise integration, OPC UA provides standardized information models and security. For deterministic real-time control, OPC UA FX over TSN (Time-Sensitive Networking) is the emerging standard in 2026, offering microsecond-level jitter guarantees on standard Ethernet. ModulesLink communication modules support all three protocols. Explore our communication modules →
How do I select the right DIN rail power supply?
Key selection criteria: 1) Output voltage matching your system (24V DC is most common), 2) Wattage rating exceeding total load by 25% safety margin, 3) Efficiency rating (80 PLUS Gold or above recommended), 4) Operating temperature range for your environment, 5) Required certifications (CE, UL, RoHS), 6) Protective features (OVP, OCP, SCP, OTP).

What is IEC 62443 and why is it important for industrial networks?
IEC 62443 is the international standard for cybersecurity in industrial automation and control systems (IACS). It defines security levels (SL 1-4), zone and conduit architecture for network segmentation, and lifecycle requirements from risk assessment through operations. With the EU Cyber Resilience Act requiring vulnerability reporting from June 2026, IEC 62443 compliance is becoming mandatory for industrial equipment sold in Europe. Read our IEC 62443 guide →
How do I secure Modbus TCP communication in my industrial network?
Modbus TCP has no native security. Best practices: 1) Network segmentation with VLANs and firewalls, 2) Encrypt traffic using VPN tunnels (IPsec/WireGuard) or TLS wrappers, 3) Deploy Modbus-aware gateways with access control and function code filtering, 4) Implement allowlist source IP filtering, 5) Enable monitoring and anomaly detection on Modbus traffic, 6) Use IEC 62443 zone/conduit architecture for defense-in-depth.

What is OPC UA FX and how does it differ from OPC UA?
OPC UA FX (Field eXchange) extends OPC UA down to the field level with deterministic publish/subscribe over TSN Ethernet. Unlike traditional OPC UA client/server which requires N×M sessions, OPC UA FX uses one-to-many pub/sub that scales efficiently. It adds controller-to-controller communication, safety integration (SIL4/PLe), and sub-millisecond determinism — replacing the need for separate real-time fieldbus protocols like PROFINET or EtherCAT.
