IEC 61800-7-302:2015

Overview

IEC 61800-7-302:2015 is an international standard developed by the International Electrotechnical Commission (IEC) focused on adjustable speed electrical power drive systems. It forms part of the IEC 61800-7 series which provides generic interfaces and profiles for power drive systems. This specific part details the mapping of profile type 2 (CIP Motion™) onto various network technologies including DeviceNet™, ControlNet™, and EtherNet/IP™. The 2015 edition updates patent information, connection formats, and adds support for an additional object to enhance interoperability.

The standard is designed to foster a generic, vendor-independent interface model for power drive systems to improve compatibility, integration, and control in industrial and automation applications.

Key Topics

• Generic Interface Model: Establishes a common interface between control systems and electrical power drives, which can be embedded in smart drives or intelligent drives.
• Profile Type 2 (CIP Motion™): A predefined profile for motion control systems, enabling consistent data handling and functional operation across different network platforms.
• Network Technology Mapping: Specifies how CIP Motion™ objects and functions map onto key industrial communication networks:
  • DeviceNet™ – a robust fieldbus network widely used for industrial automation.
  • ControlNet™ – offering high-speed control communications suitable for real-time control.
  • EtherNet/IP™ – Ethernet-based industrial network for extensive connectivity and flexibility.
• Connection Formats: Defines fixed and variable connection formats to ensure appropriate data exchange sizes and structures between controllers and drives.
• Data Types & Object Models: Outlines standard data types for inputs and outputs and maps device objects tailored to each network technology to harmonize communication.
• Updates: Incorporates recent patent information updates and refines connection points for streamlined implementations.

Applications

IEC 61800-7-302:2015 is essential for:

• Drive Manufacturers: Enables them to develop drives with standardized interfaces which simplify integration with automation systems and reduce proprietary development efforts.
• Control System Developers: Facilitates the creation of hardware and software capable of universally communicating with various drives without needing technology-specific adjustments.
• System Integrators: Provides a common framework for integrating drives into industrial networks, thereby lowering complexity, cost, and deployment times.
• Industrial Automation: Improves interoperability for applications such as conveyor systems, robotic controls, CNC machinery, and process control where precise motor control via networks is critical.
• Motion Control Systems: Supports complex motion sequences by enabling consistent communication and control mechanisms over diverse network infrastructures.
