About This Item
IEC 61804-2:2018 defines the specification of the function block concept for process control and electronic device description language (EDDL), making it a key reference for organizations that need consistent device representation and control-system integration. For engineering teams, procurement reviewers, and compliance specialists, it helps frame how device information is structured and assessed within automation workflows. IEC 61804-2:2018 is relevant where technical review, documented evaluation, and operational consistency are important across process control environments.
What is IEC 61804-2:2018?
IEC 61804-2:2018 describes the function block concept used in process control and EDDL-based device descriptions. Its purpose is to support a clear technical model for how device functions are represented, exchanged, and evaluated in automation systems. In practice, that can assist with engineering documentation, conformity assessment preparation, and verification activities where consistent interpretation of device behavior and interface structure is needed. The document is particularly useful when teams need a reliable compliance reference for control-system integration.
Applications of IEC 61804-2:2018
This reference is typically used in process automation projects where devices, control systems, and engineering tools must share a common functional description. It may support product evaluation, software integration, laboratory evaluation, and validation of device documentation during procurement or system acceptance. Organizations working on industrial control architectures, configuration tools, or device data handling may use IEC 61804-2:2018 to align technical assessment activities with a defined function block concept and to improve consistency across testing workflows and compliance workflows.
Why is IEC 61804-2:2018 important?
The value of IEC 61804-2:2018 lies in helping teams reduce integration risk and improve consistency when evaluating process control devices and their electronic descriptions. A defined function block concept supports clearer technical validation, easier comparison between devices, and more structured conformity assessment preparation. It can also aid procurement decisions by giving stakeholders a common basis for reviewing functional claims and documentation. For organizations managing quality assurance, interoperability, and controlled implementation, it provides a practical foundation for more dependable technical compliance.
