实时控制当然意味着速度,快速的响应时间,大多是多任务系统。然而,仅仅是速度是不够的。由于采用高效而又更快速的微处理器,从而使实时控制变得容易操作而且价格低廉。 1.可定义单个程序工作的时间间隔。实时响应品质的测量就是保持时间间隔的精确性(等距离时间间隔) 2.重复执行单个顺序的实际时间(有效循环时间会有很少的变动),可以指示出来(跳动) 3.对应于事件的最大的响应时间应尽可能地短,但每种情况均应通告。(延迟时间) 自1992年Klopper & Wiege开始推出运行时系统ProConOS,现已能提供这种类型的多任务操作系统。基于不同的实时多任务操作系统,ProConOS能为不同类型的硬件平台(Intel 80x86/Pentum;Motorola 680x0,Power PC)提供PLC的功能。在这种配置下,ProConOS能使用全部处理器时间,ProConOS与大多数典型的PLC操作系统的不同之处就是它
Of course, real-time control means speed, fast response time, mostly multitasking systems. However, speed alone is not enough. Due to the efficient and faster microprocessor, real-time control becomes easier to operate and less expensive. 1. Define the time interval for a single program to work. The measurement of real-time response quality is to maintain the accuracy of the time interval (equidistant interval) 2. Repeat the execution of a single sequence of real time (the effective cycle time there will be little change), can be indicated (beating) 3. Corresponds to the event The maximum response time should be as short as possible, but in each case should be announced. (Delay) Since Klopper & Wiege launched the runtime system ProConOS in 1992, this type of multitasking operating system is now available. Based on different real-time multitasking operating systems, ProConOS provides PLC functionality for different types of hardware platforms (Intel 80x86 / Pentum; Motorola 680x0, Power PC). With this configuration, ProConOS can use the full processor time, and ProConOS differs from most typical PLC operating systems in that it
