IEC 61334-4-42:1996

IEC 61334-4-42:1996 is a technical reference for distribution automation using distribution line carrier systems, with a specific focus on data communication protocols at the application layer. For engineers and compliance teams, it helps define how application-level communication should be organized within a broader distribution automation architecture. IEC 61334-4-42:1996 is relevant where technical evaluation, interoperability review, or procurement decisions depend on a clear understanding of protocol behavior in utility communication systems.

What is IEC 61334-4-42:1996?

This document forms part of the IEC 61334 series and addresses application protocols for distribution line carrier systems. Its scope is centered on the application layer, which is typically where message handling, functional interaction, and communication behavior are defined for automated distribution environments. As a result, it is useful during engineering documentation review, technical assessment, and conformity assessment preparation for systems that rely on structured data exchange over distribution networks.

Applications of IEC 61334-4-42:1996

IEC 61334-4-42:1996 is commonly relevant in utility automation workflows involving communication between field equipment, control systems, and associated network infrastructure. It may support design and verification activities for distribution automation solutions that use line carrier communication methods, especially where application-layer consistency is important for operational coordination. Procurement teams, laboratories, and system integrators may use it as a compliance reference when evaluating protocol alignment and documenting technical requirements.

Why is IEC 61334-4-42:1996 important?

Clear application-layer definitions help reduce integration risk and improve operational consistency across connected automation equipment. IEC 61334-4-42:1996 can support testing workflows, technical validation, and documented evaluation by giving stakeholders a common reference for protocol-related expectations. It is also useful in regulatory preparation and quality workflows, where repeatable communication behavior and traceable engineering decisions matter for compliance, interoperability, and reliable system deployment.
