If there are too many loops to be completed,for example,a controller collects thousands of points and completes the calculation of hundreds of loops,the danger is too concentrated.In this case,the danger must be dispersed.With the development of computer technology,the computing power,storage capacity and reliability of computers are continuously improved,and the tasks completed by a computer can also be increased.The completed tasks can also be concentrated.In addition,redundant technologies such as controllers and networks have also been developed,and control operations can also be concentrated.
如果所要完成的回路太多,如一个控制器采集几千点、完成几百个回路的运算,危险又太集中。在这种情况下,危险必需分散。随着计算机技术的发展,计算机的运算能力、存储容量和可靠性不断提高,一台计算机所完成的任务也可以增加。完成的任务也可集中一点。另外,控制器、网络等冗余技术也得到了发展,控制运算也可集中一些。
