SIST EN 61784-3-12:2010/A1:2020

Overview

SIST EN 61784-3-12:2010/A1:2020 is an important Slovenian standard based on EN 61784-3-12:2010/A1:2019 and IEC 61784-3-12:2010/A1:2019. This standard falls under the broader series for industrial communication networks - profiles and specifically addresses functional safety fieldbuses with additional specifications for Communication Profile Family 12 (CPF 12). This amendment (A1:2020) clarifies and corrects the state tables for Fail Safe over EtherCAT (FSoE) Slaves, providing essential adjustments for reliable and safe automation networking.

The standard is applicable to industrial process measurement, control, and automation environments where robust and safe fieldbus communication protocols are essential to ensure functional safety for machinery and processes.

Key Topics

SIST EN 61784-3-12:2010/A1:2020 covers several essential aspects for the implementation of functional safety over CPF 12 fieldbuses:

• Functional Safety: Guidelines for developing and operating fieldbus systems where safety functions are critical.
• CPF 12 Enhancements: Amendments with specific corrections for the state tables used in FSoE (Fail Safe over EtherCAT) Slaves.
• Fieldbus Communication: Focused on reliable and safe data transfer over industrial networks.
• Error Correction: The amendment addresses invalid parameter assignments and missing actions in state transitions, improving the clarity and correctness of safety implementation.
• Compliance with International Standards: Ensures alignment with global automation and safety protocols as defined by IEC and CENELEC.
