IEC 62734:2014+A1:2019根据OSI基本参考模型ISO/IEC 7498-1(例如，PhL、DL等)提供规范。它旨在为非关键监控、警报、监督控制、开环控制和闭环控制应用提供可靠和安全的无线操作。它定义了一套协议，包括系统管理、网关注意事项和安全规范，用于与固定、便携式和缓慢移动的设备的低数据速率无线连接，这些设备通常在严重的能量和功率限制下运行。应用重点是过程自动化监测和控制的性能需求，其中可以容忍至少100ms量级的端到端通信延迟。该合并版本由第一版（2014年）及其修正案1（2019年）组成。因此，除本出版物外，无需下令修订。

IEC 62734:2014+A1:2019 provides specifications in accordance with the OSI Basic Reference Model, ISO/IEC 7498-1, (e.g., PhL, DL, etc.). It is intended to provide reliable and secure wireless operation for non-critical monitoring, alerting, supervisory control, open loop control, and closed loop control applications. It defines a protocol suite, including system management, gateway considerations, and security specifications, for low-data-rate wireless connectivity with fixed, portable, and slowly-moving devices, often operating under severe energy and power constraints. The application focus is the performance needs of process automation monitoring and control where end-to-end communication latencies on the order of at least 100 ms can be tolerated. This consolidated version consists of the first edition (2014) and its amendment 1 (2019). Therefore, no need to order amendment in addition to this publication.
