    • A programmable controller is disclosed for the purpose of controlling devices such as machine tools and other machinery, and which is often mated with a host computer numerical controller. The programmable controller is configured such that certain user-designated "fast-scan" outputs can operate at much higher speeds than non-designated "normal" outputs, thereby greatly increasing the response time and efficiency of the operations that are controlled by those fast-scan outputs. The programmable controller uses a processor which scans through its user-definable program (including the value of all system inputs and outputs) before it attempts to change the value of any of its outputs. The physical input/output (I/O) interfaces are located on I/O racks, each of which also includes an intelligent bus adaptor. The intelligent bus adaptor includes its own processor which periodically communicates with the processor in the programmable controller. The intelligent bus adaptor's processor controls the fast-scan outputs located on that particular I/O rack within very short time intervals, and allows for a response time that is an order of magnitude faster than the response time of normal outputs of the programmable controller.
    • 公开了可编程控制器,用于控制诸如机床和其他机械的设备,并且其通常与主机数字控制器配合。 可编程控制器被配置为使得某些用户指定的“快速扫描”输出可以以比非指定的“正常”输出高得多的速度运行,从而大大增加由那些快速扫描输出控制的操作的响应时间和效率, 扫描输出。 可编程控制器在尝试更改其任何输出的值之前,使用一个处理器来扫描其用户可定义的程序(包括所有系统输入和输出的值)。 物理输入/输出(I / O)接口位于I / O机架上,每个接口还包括智能总线适配器。 智能总线适配器包括其自己的处理器,其周期性地与可编程控制器中的处理器进行通信。 智能总线适配器的处理器在非常短的时间间隔内控制位于特定I / O机架上的快速扫描输出,并且允许响应时间比可编程控制器的正常输出的响应时间快一个数量级。
