What is BS EN 61158-5-13 - Type 13 application layer service definition about?
BS EN 61158-5-13 is part of a series produced to facilitate the interconnection of automation system components. BS EN 61158-5-13 is related to other standards in the set as defined by the “three-layer” fieldbus reference model described in IEC 61158-1.
BS EN 61158-5-13 provides common elements for basic time-critical and non-time-critical messaging communications between application programs in an automation environment and material specific to Type 13 fieldbus. The term “time-critical” is used to represent the presence of a time window, within which one or more specified actions are required to be completed with some defined level of certainty. Failure to complete specified actions within the time window risks failure of the applications requesting the actions, with attendant risk to equipment, plant and possibly human life.
BS EN 61158-5-13 defines in an abstract way the externally visible service provided by the different Types of the fieldbus Application Layer in terms of:
- An abstract model for defining application resources (objects) capable of being manipulated by users via the use of the FAL service
- The primitive actions and events of the service
- The parameters associated with each primitive action and event, and the form which they take
- The interrelationship between these actions and events, and their valid sequences
Who is BS EN 61158-5-13 - Type 13 application layer service definition for?
BS EN 61158-5-13 on industrial communication networks is useful for:
- IT industry /software programmers
- Internet engineering task forces
- Internet service providers
- Telecommunication companies
- The automation industry
Why should you use BS EN 61158-5-13 - Type 13 application layer service definition?
The application service is provided by the application protocol making use of the services available from the data link or other immediately lower layer.
BS EN 61158-5-13 defines the application service characteristics that fieldbus applications and/or system management may exploit.
BS EN 61158-5-13 specifies the characteristics of conceptual application layer services suitable for time-critical communications, and thus supplement the OSI Basic Reference Model in guiding the development of application layer protocols for time-critical communications.
BS EN 61158-5-13 provides migration paths from previously-existing industrial communications protocols. By using BS EN 61158-5-13 guidelines, you can facilitate industrial automations that accelerate productivity.
