IEC 61158「PROFINET现场总线标准」标准解读
📌IEC 61158《PROFINET现场总线标准》是起重机领域的重要技术规范。该标准是IEC制定的PROFINET现场总线标准。
This standard provides a unified technical basis for designers, inspection agencies, and users. Krude Heavy Industry strictly adheres to the technical requirements of this standard throughout the product development and manufacturing processes to ensure the equipment’s compliance and reliability.
Scope and Purpose of the Standard
IEC 61158《PROFINET现场总线标准》主要规定了起重机PROFIN相关的技术要求和安全指标，适用于额定起重量0.5t以上的各类起重机械。该标准不仅覆盖新设备的设计与制造环节，还对在用设备的检验、维护和改造提出了明确的技术指导。作为起重机标准体系中的关键组成部分，该标准与EN 13001系列、ISO 4309等标准协调一致，共同构成了完整的技术规范体系。标准中明确的技术参数和安全系数要求，为设计人员提供了清晰的设计依据，也为第三方检验机构的型式试验和出厂检验提供了可量化的判定标准。
Core Technical Specifications
根据IEC 61158的技术规定，PROFINET的设计与制造需要满足一系列严格的技术参数要求。这些参数的确定基于大量试验数据和安全工程理论，覆盖了从材料选用到结构设计的全过程。标准规定的安全系数取值范围充分考虑起重机械在恶劣工况下的疲劳寿命和极限载荷条件。

Inspection Requirements and Frequency
Factory inspections shall be conducted unit by unit by the quality inspection department at the manufacturer’s facility. Equipment that passes inspection shall be accompanied by a detailed inspection report and a certificate of conformity. Type testing shall be conducted when a new product enters production for the first time, when production is transferred to a different facility, or when major structural changes are made. The periodic inspection interval for in-service equipment shall be determined based on the duty class and operating environment, and generally shall not exceed 12 months.
| Project | Technical Requirements | Note |
|---|---|---|
| Communication Cycle | IRT同步性测试 | 季度+抖动≤1μs |
| 设备状态 | IO设备在线率 | 月度+告警记录 |
| 诊断功能 | 通道级诊断模拟 | 季度+完整验证 |
| PROFIsafe | 安全功能测试 | 月度+验证SIL等级 |
Safety Operation and Management Requirements
The standard places particular emphasis on the importance of operator qualifications and training, requiring that all operators undergo specialized training and obtain the appropriate qualifications before being allowed to work. Equipment-using entities should establish a comprehensive equipment record management system to document in detail the entire process of installation, use, maintenance, and inspection. Any identified safety hazards must be addressed in accordance with the corrective action procedures specified in the standard to ensure that the equipment remains in a safe and controlled condition at all times.
