What is BS EN IEC 61804-2 – Functional blocks and EDDL about?
The IEC 61804 series focuses on function blocks for process control and electronic device description language (EDDL). BS EN IEC 61804-2:2018 provides a conceptual function block specification, which can be mapped to specific communication systems and their accompanying definitions by industrial groups and specify the EDDL.
The EDDL fills the gap between the conceptual function blocks specification of BS EN IEC 61804-2 and product implementation. BS EN IEC 61804-2:2018 is applicable to function blocks for process control. BS EN IEC 61804-2:2018 specifies function blocks by using the result of a harmonization work as regards several elements.
BS EN IEC 61804-2:2018 specifies an EDDL for the description of the properties of automation system components. The specified language can describe:
- Device parameters and their dependencies
- Device functions, for example, simulation mode, calibration
- Graphical representations, for example, menus
- Interactions with control devices
Who is BS EN IEC 61804-2 - Functional blocks and EDDL for?
BS EN IEC 61804-2 on Functional blocks and EDDL is useful for:
- Manufacturers of functional blocks-based devices (control devices)
- Software companies/IT firms
- Engineers responsible for the specification, engineering, and implementation of control systems
- Automation industries
Why should you use BS EN IEC 61804-2 - Functional blocks and EDDL?
An electronic device description (EDD) contains all the device parameters of an automation system component. The technology used to describe an EDD is called EDDL. The EDDL provides a set of scalable basic language elements to handle simple, complex or modular devices. The EDDL is a descriptive language based on an ASCII format with a clear separation between data and program.
BS EN IEC 61804-2:2018 provides you with algorithms for use in application functional blocks, transducer blocks and device blocks. These algorithms process signal algorithms, and management.
BS EN IEC 61804-2:2018 covers principles of the electronic device description development process and concept of electronic device description.
