About This Item
IEC 61158-5-19:2019 defines the application layer service definition for Type 19 elements within Industrial communication networks - Fieldbus specifications - Part 5-19: Application layer service definition - Type 19 elements. For engineering teams, test laboratories, and procurement specialists, it serves as a technical reference for evaluating how Type 19 fieldbus communication services are structured and used in documented evaluation, conformity assessment, and system integration workflows. IEC 61158-5-19:2019 is relevant when consistency in application-layer behavior matters across connected industrial equipment and control environments.
Purpose of IEC 61158-5-19:2019
The purpose of this technical document is to specify the service definition at the application layer for Type 19 elements within the IEC 61158 fieldbus framework. It supports technical review by describing the communication services that higher-level implementation and interoperability decisions may depend on. In practice, it helps engineers align product design, protocol assessment, and validation activities with a defined service model, reducing ambiguity during specification reviews and compliance preparation.
Compliance applications of IEC 61158-5-19:2019
IEC 61158-5-19:2019 is commonly used in compliance workflows for industrial communication equipment that relies on fieldbus-based application-layer behavior. It may support technical documentation, product evaluation, and laboratory testing where service definitions need to be checked against implementation requirements. Organizations involved in automation systems, networked controllers, and related industrial electronics may use it during engineering documentation review, verification activities, and conformity assessment preparation to confirm operational consistency across devices and subsystems.
Benefits of IEC 61158-5-19:2019
Using this reference can improve engineering validation by giving teams a clear basis for assessing Type 19 application-layer services during design and test planning. It supports quality workflows by helping reduce interpretation differences between suppliers, integrators, and test teams. For procurement and compliance teams, the document can aid technical assessment, risk management, and documented evaluation of fieldbus-related products, while also helping maintain consistency in verification activities and conformity assessment records.
- Defines application-layer service expectations for Type 19 fieldbus elements
