What is EN ISO 14249-2014

Introduction

EN ISO 14249-2014 is a technical standard that provides guidelines and requirements for the documentation of computer programs used in industrial automation systems. This standard was developed by the International Organization for Standardization (ISO) and the European Committee for Standardization (CEN).

Purpose and Scope

The purpose of EN ISO 14249-2014 is to ensure that the documentation of computer programs in industrial automation systems is complete, accurate, and consistent. It defines the content and structure of the documentation, as well as the methods for its preparation and maintenance.

The scope of this standard covers all stages of the software development process, from initial design to final implementation. It applies to both new programs and modifications to existing programs. The standard also specifies the information that should be included in the documentation, such as program structure, user interface, and system requirements.

Key Requirements

EN ISO 14249-2014 outlines several key requirements for the documentation of computer programs in industrial automation systems. These include:

1. Identification and version control: The documentation should clearly identify the program and its version, as well as any changes or updates made to it.

2. Description of functions: The documentation should provide a detailed description of the program's functions, including input and output requirements, processing logic, and error handling procedures.

3. User instructions: The documentation should include clear and concise instructions on how to use the program, including installation and setup procedures, user interface navigation, and troubleshooting.

4. Technical specifications: The documentation should specify the technical requirements and constraints of the program, such as hardware and software dependencies, system compatibility, and performance metrics.

5. Backup and recovery procedures: The documentation should outline procedures for backing up and recovering program data to prevent loss or corruption.

Conclusion

In conclusion, EN ISO 14249-2014 is a crucial standard for ensuring the proper documentation of computer programs used in industrial automation systems. By following the guidelines and requirements outlined in this standard, organizations can improve program reliability, maintainability, and overall system performance. Compliance with this standard also promotes interoperability and facilitates knowledge transfer between different stakeholders involved in the development and operation of industrial automation systems.
