About This Item
IEC 61158-4-25:2019 defines the data-link layer protocol specification for Type 25 elements within Industrial communication networks - Fieldbus specifications. For engineering teams, test laboratories, and procurement specialists, it serves as a focused technical reference for understanding how Type 25 communication behavior is structured at the protocol level. IEC 61158-4-25:2019 is relevant where documented evaluation, technical validation, and interoperability review are part of the workflow for fieldbus-based automation and control systems.
IEC 61158-4-25:2019 standard overview
The scope indicated by Industrial communication networks - Fieldbus specifications - Part 4-25: Data-link layer protocol specification - Type 25 elements suggests a document centered on protocol behavior at the data-link layer. That makes it useful during technical review, conformity assessment, and implementation verification for systems that rely on fieldbus communication. As a primary technical reference, it helps align design, testing, and compliance activities around the expected communication structure for Type 25 elements.
Applications of IEC 61158-4-25:2019
This document is typically consulted in automation projects, industrial network integration, and laboratory evaluation of fieldbus communication behavior. It may support equipment development, system qualification, and interoperability testing where data-link layer protocol details are needed for engineering documentation or compliance workflows. Organizations involved in control systems procurement, certification preparation, or operational validation may use IEC 61158-4-25:2019 to confirm that technical assumptions match the relevant protocol requirements before deployment.
Why IEC 61158-4-25:2019 matters
Clear data-link layer definitions help reduce implementation risk and improve consistency across design, testing, and integration activities. IEC 61158-4-25:2019 can support safety-related technical review, performance verification, and quality assurance by giving teams a stable reference for Type 25 fieldbus behavior. It is also valuable in procurement and conformity assessment preparation, where documented compliance evidence and technical validation often depend on precise protocol interpretation and repeatable testing workflows.
