What is BS EN IEC 61804-5 — EDDL Builtin library about?
BS EN IEC 61804-5 is the fifth part of an international multi-series standard that discusses devices and integration in enterprise systems.
BS EN IEC 61804-5 specifies the EDDL builtin library and provides the profiles of the various fieldbuses.
BS EN IEC 61804-5 specifies technical features such as terms, definitions, acronyms, abbreviated terms, conventions for builtin descriptions, builtin categories, EDDL builtin library, and builtins return codes for function blocks (FB) for process control and electronic device description language (EDDL).
Who is BS EN IEC 61804-5 — EDDL Builtin library for?
IEC 61804-5 on EDDL Builtin library is useful for:
- Sensors manufacturing companies
- Hydraulic valves manufacturing industries
- Human-machine interfaces developers
- Electronic device manufacturing companies
Why should you use BS EN IEC 61804-5 — EDDL Builtin library?
An electronic device description (EDD) contains all device parameter(s) of an automation system component. The technology used to describe an EDD is called electronic device description language (EDDL). The EDDL is a descriptive language based on an ASCII format with a clear separation between data and program.
BS EN IEC 61804-5 contains a list of builtins that can be used inside of EDDL methods. It defines the functionality and parameters for each builtin and describes how EDDL variables can be referenced from inside EDDL methods. It provides an alphabetical overview of the EDDL builtin library and specifies the profile per communication technology.
BS EN IEC 61804-5 describes builtin subroutines for the users, which can be used in an EDD. The builtins support the user or device interactions. It demonstrates examples for typical user interactions, like user inputs of VARIABLE values or acknowledgments. It contains the library of builtins.
What’s changed since the last update?
BS EN IEC 61804-5:2020 supersedes BS EN 61804‑5:2015, which is withdrawn. BS EN IEC 61804-5:2020 includes some technical changes with respect to the previous edition. These include:
- Communication profiles ISA100 and GPE were added.
- The following builtins have been deprecated:
