Overview
EN 60870-5-1:1993 - Telecontrol equipment and systems - Part 5: Transmission protocols - Section 1: Transmission frame formats (equivalent to IEC 870-5-1:1990) defines the basic framing and link-layer transmission rules for telecontrol/telemetry communications. The standard covers asynchronous data transmission using half‑duplex and duplex link protocols with window size one, and specifies required services for the link and physical layers to meet data integrity needs in telecontrol applications.
Key topics and technical requirements
- Transmission modes: Support for asynchronous transmission in both half‑duplex and duplex link configurations.
- Window size: Protocol operation with window size one for message transfers (single-frame acknowledgement behavior).
- Link and physical layer services: Basic service requirements that link and physical layers must provide for telecontrol use.
- Frame formats: Rules for coding, formatting and synchronizing data frames, including handling of variable and fixed-length frames.
- Frame integrity: Mechanisms and format constraints intended to ensure specified data integrity for telecontrol messages (e.g., frame delimiting and error-detection considerations implied by format standards).
- Protocol scope: Focused on message transfer and frame-level behavior; it defines how frames are constructed and exchanged rather than higher-level application semantics.
Applications
EN 60870-5-1 is directly applicable to systems requiring reliable telecontrol and telemetry over serial/asynchronous links, including:
- SCADA communications between control centers and remote terminal units (RTUs)
- Power system telecontrol (substation to control center links)
- Industrial remote control and telemetry installations
- Legacy serial-line communications where window size one and frame-level synchronization are appropriate
Implementers rely on the standard when designing or validating communication interfaces that must interoperate across vendors while meeting basic integrity and framing requirements.
Who should use this standard
- Protocol implementers and firmware developers for RTUs, PLCs and communication modules
- Equipment manufacturers building telecontrol/SCADA hardware
- System integrators and SCADA engineers specifying link-layer behavior for installations
- Test laboratories and compliance teams verifying frame formats and link behavior
