Overview
IEC 61784-5-11:2013 is an international standard developed by the International Electrotechnical Commission (IEC) that specifies the installation profiles for CPF 11, known as TCnet, within industrial communication networks. As part of the IEC 61784 series on industrial fieldbus communication profiles, this standard provides comprehensive guidelines and requirements for the installation of fieldbus systems using CPF 11 technology. The third edition, published in 2013, updates and replaces the previous 2010 edition, incorporating new normative annexes and technical improvements.
This standard is crucial for engineers and technicians involved in the planning, installation, verification, and maintenance of CPF 11 fieldbus networks in industrial environments. It ensures interoperability, reliability, and safety when installing fieldbus communication systems for industrial control applications.
Key Topics
- Installation Profiles for CPF 11 (TCnet): Detailed specifications on installation practices that cater to TCnet architectures, including two main profiles: TCnet-star (CP 11/1) and TCnet-loop 100 (CP 11/2), with specific guidance for each.
- Installation Planning: Covers safety, security, electromagnetic compatibility (EMC), environmental considerations, and cabling requirements according to ISO/IEC 24702.
- Network Characteristics and Topology: Defines network topology types, device locations, and network capabilities customized for CPF 11 systems.
- Cabling and Components Selection: Guidelines on cable types, connector hardware, terminators, shielding, earthing, bonding, and cable routing to optimize performance and protect against interference.
- Installation Verification and Acceptance Testing: Methods for verifying installation correctness, including shield earthing, connector status, cabling conformity, and function tests for both Ethernet and non-Ethernet cabling systems.
- Installation Documentation and Maintenance: Best practices for documenting cabling layouts, coding, labelling, and ongoing maintenance and troubleshooting procedures.
- Wireless Installation Considerations: Requirements tailored for wireless CPF 11 setups, ensuring robust installation and reliable communication.
