Overview
EN IEC 61139-3:2023 (Industrial networks - Single-drop digital communication interface - Part 3: Wireless extensions) specifies a wireless extension to the SDCI technology defined in IEC 61131-9. Often called SDCI wireless, this standard defines the wireless services and protocol layers (physical, data link and application) for W‑Masters and W‑Devices, aligned with the ISO/OSI model. It targets single-drop (point-to-point) digital links for small sensors and actuators in industrial automation. Note: the document does not cover integration into higher-level systems such as fieldbuses.
Key topics and requirements
- Layered protocol specification: defines the Physical Layer (PL), Data Link Layer (DL‑A) and Application Layer behaviors required for SDCI wireless interoperability.
- Air interface & cell concept: describes topology, W‑Cycles, W‑Frames and slotning mechanisms (uplink/downlink, single/double slot transmission).
- Medium access and coexistence: MAC rules, frequency channels, hopping algorithms, blocklisting and wireless quality supervision to ensure reliable operation in industrial environments.
- Device roles & procedures: behavior and services for W‑Master, W‑Device and W‑Bridge including scan (discovery), pairing/unpairing, automatic pairing, roaming and “I am alive” supervision.
- Physical layer details: modulation, carrier calibration, transmission power, antenna requirements, receiver sensitivity, preamble/syncword, CRC and data whitening.
- Conformity & coexistence references: normative references include IEC 61131-9, IEC/TR 62453-61, ETSI EN 300 328, ETSI EN 300 440 and FCC §15.247 - supporting regulatory compliance and coexistence management.
- Testable state machines & services: PL and DL state machines and service primitives are specified to support implementation, testing and certification.
Applications and who uses this standard
- Device manufacturers building wireless sensors, actuators and I/O modules that implement SDCI wireless for factory automation and process control.
- Control system OEMs integrating wireless single-drop links at the sensor/actuator level.
- System integrators and automation engineers designing wireless cells, planning RF coexistence and defining device roles.
- Test labs and certification bodies verifying interoperability, conformity and regulatory compliance.
- Standards committees and product managers aligning roadmaps to IEC 61131-9 ecosystems.
Practical use cases include replacing wired single-drop links with low-power wireless connections for distributed sensors and actuators, simplifying retrofit installations, and enabling flexible machine layouts while maintaining deterministic SDCI behavior.
