本标准定义了称为智能外围接口（IPI）的一系列标准中的设备通用命令集部分，IPI是一种高性能通用接口 并行外围接口。这两种材料适用于设备通用命令集支持的所有设备类别，以及面向特定设备类别的材料。在本文件中，后一条款适用于磁带机。 第二版取消并取代1990年出版的第一版，构成技术修订版。自第一版起，添加或更改了以下项目: -修订范围； -增加了属性用法（第4.10款，随后的条款重新编号）； -增加位置控制命令的新参数（第7.2款）。 ISO/IEC 9318-4补充了其他智能外围接口标准。

This standard provides a definition of the device-generic command set portion of a series of standards called the Intelligent Peripheral Interface (IPI), a high performance, general-purpose parallel peripheral interface. Both material that is useful across all classes of device that the device-generic command sets can support, and material oriented to particular device classes is included. In this document the latter clauses are intended for use with Magnetic Tape Drives. This second edition cancels and replaces the first edition published in 1990, and constitutes a technical revision. The following items have been added or changed since the first edition: - revised scope; - attribute usage was added (subclause 4.10, subsequent clauses were renumbered); - addition of new parameters for position control command (subclause 7.2). ISO/IEC 9318-4 complements other Intelligent Peripheral Interface standards.
