标准摘要
[中文适用范围]: 本技术规范旨在为开发基于微处理器的仪器的评估方法提供背景信息。评估首先从对流程、操作员和外部系统的外部和内部信息流进行分析开始。然后确定仪器中的主要功能块。通过使用 4.2 和 4.3 中给出的检查表,可以识别可能嵌入到待评估仪器功能块中的功能和属性。第 4.4 款给出了一个清单,用于识别待评估仪器的相关影响条件。根据仪器的应用,本技术规范的用户可能必须定义进一步的功能和属性或影响条件。 [外文原描述]: This Technical Specification aims at providing background information for developing evaluation methods for microprocessor-based instruments. An evaluation starts with analysis of the instrument in terms of the external and internal information flows from and to the process, the human operator and external systems. Main function blocks in the instrument are then identified. By using the checklists given in 4.2 and 4.3, the functions and properties that may be embedded in the function blocks of the instrument to be evaluated can be identified.
