Overview
EN 61334-4-42:1996 (CLC; also published as IEC 1334-4-42) defines the application layer protocols for distribution automation over distribution line carrier systems. The standard describes the rules for designing an Application Service Element (ASE) including the ISO connectionless ACSE (Application Control Service Element) and the DLMS Application Service Element. It focuses on ensuring consistent, interoperable application-layer behavior for data communication protocols used in power distribution automation.
Key topics
- Application service element design rules - specifies how an ASE should be structured to provide services at the application layer for distribution line carrier communications.
- ISO connectionless ACSE - provides rules for using the ISO connectionless Application Control Service Element in distribution automation contexts.
- DLMS Application Service Element - describes the application-layer support needed to use DLMS (Device Language Message Specification) over line carrier systems.
- Application-layer interoperability - guidance to ensure devices from different vendors can exchange application data reliably.
- Scope within OSI model - focuses on the application layer (user services, session-less interaction), complementing lower-layer physical and data link specifications in the EN/IEC 61334 family.
Applications
EN 61334-4-42 is intended for practical use in:
- Distribution automation systems that use powerline carrier (PLC) links to exchange operational data.
- Smart grid and substation communications where application-layer services (metering, control, monitoring) must be standardized.
- Implementation of DLMS/COSEM stacks over distribution line carrier networks requiring defined application service behavior.
- Interoperability testing and conformance for manufacturers and utilities verifying application-layer behavior.
Practical benefits include improved interoperability between meters, remote terminal units (RTUs), and control systems; clearer development requirements for firmware and protocol stacks; and reduced integration risk for distribution line carrier deployments.
Who uses this standard
- Utility communications engineers and system architects
- Device manufacturers (meters, RTUs, PLC modems)
- Software developers implementing DLMS or ACSE stacks
- Test laboratories and certification bodies
- Standards and compliance teams in energy sector organizations
