IEC 61784-1-19:2023

Overview

IEC 61784-1-19:2023 is an international standard published by the International Electrotechnical Commission (IEC) that defines Communication Profile Family 19 (CPF 19) within industrial networks. This standard focuses on fieldbus profiles used for industrial communication protocols in factory manufacturing and process control environments. CPF 19 specifically covers protocol-specific communication profiles built on the IEC 61158 series (Types 24 and 27) and other relevant standards. The defined profiles are essential for the design and interoperability of fieldbus devices, providing a consistent and compatible framework for communication services and protocols.

The IEC 61784-1-19:2023 standard supports seamless integration, configuration, and management of devices on industrial networks, promoting automation, reliability, and scalability in manufacturing systems.

Key Topics

• Communication Profile Family 19 (CPF 19): Defines multiple communication profiles based on IEC 61158 protocols focusing on Types 24 and 27.
• Protocol Specific Profiles (CPs): CPF 19 encompasses several Communication Profiles such as MECHATROLINK-II (CP 19/1), M-III (CP 19/2), and Σ-LINK II (CP 19/3) that specify physical, data-link, and application layer configurations for device communication.
• Protocol Layer Definitions:
  • Physical Layer: Specifies electrical and physical parameters for signal communication.
  • Data-Link Layer: Establishes service selections and protocols for managing network data transfer.
  • Application Layer: Describes device-specific services, classes, and protocol constraints essential for operational control and data handling.
• Interoperability and Device Design: The profiles ensure that device manufacturers comply with standardized services and parameter constraints enabling multi-vendor device interoperability.
• Normative References: The standard extensively references IEC 61158 and IEC 61784-2-19 for detailed protocol families and profiles.
• Standards Compliance: CPF 19 profiles are based on published IEC international standards or other validated standards from recognized organizations.

Applications

IEC 61784-1-19:2023 and the defined CPF 19 profiles are widely applied in the following areas:

• Factory Automation: Facilitating reliable, real-time communication between controllers, sensors, actuators, and other factory floor devices.
• Process Control: Enhancing communication consistency and safety in continuous industrial processes such as chemical manufacturing and oil refining.
• Robotics and Mechatronics: Standardizing communication protocols for motion control and complex machine automation using MECHATROLINK profiles.
• Device Interoperability: Enabling industrial equipment from multiple vendors to interoperate effectively within a unified network.
• Network Design and Implementation: Assisting system integrators and engineers in configuring compliant fieldbus networks according to international best practices.
• Safety and Diagnostics: Supporting enhanced network diagnostics and safety mechanisms at protocol and device levels for robust factory systems.

Related Standards

• IEC 61158 series: Defines the fieldbus communication protocols upon which CPF 19 profiles are based, especially Types 24 and 27.
• IEC 61784-2-19: Specifies additional Communication Profile Family 19 profiles and protocol details complementing IEC 61784-1-19.
• IEC 61784 series: A broader collection of standards covering industrial network profiles for various communication systems.
• International Electrotechnical Vocabulary (IEV): Provides standardized terminology related to electrotechnology referenced in CPF 19 documentation.
• Other IEC and ISO standards: Related to industrial automation communication and network interoperability standards.
