    • An address bus control system is provided of the type in which a controller including a central processing unit is connected through an address bus and a data bus to hardware modules which control equipment to be controlled. An address space defined by an address bus includes a discrimination space for discriminating the attribute of the hardware module and a function space for allocating and clearing an address space for a function interface of the hardware module. The attribute of a hardware module connected to a connector having a corresponding address is recognized using the discrimination space. The function interface of each hardware module is assigned a space within the function space in accordance with the contents of the discrimination space in concern, or the assigned space is canceled. An address of the function space can be allocated to only a necessary function interface, merely by connecting the hardware module to the connector, allowing to set up hardware modules equal to or larger than the total address space.
    • 提供地址总线控制系统,其中包括中央处理单元的控制器通过地址总线和数据总线连接到控制要控制的设备的硬件模块。 由地址总线定义的地址空间包括用于识别硬件模块的属性的鉴别空间和用于分配和清除硬件模块的功能接口的地址空间的功能空间。 使用识别空间来识别连接到具有相应地址的连接器的硬件模块的属性。 每个硬件模块的功能接口根据关注的鉴别空间的内容在功能空间内分配一个空间,或者分配的空间被取消。 仅通过将硬件模块连接到连接器,可以将功能空间的地址分配给必要的功能接口,允许设置等于或大于总地址空间的硬件模块。
