请问DeltaV系统的控制负荷和通讯负荷问题？ 以下英文资料摘自 deltav books online 10.3 the fretim parameter in the deltav controller represents the percentage of time available to run control modules. it is recommended that the modules configured in the controller (when downloaded) allow for a fretim value no less than 5-10. you can improve a fretim by slowing down the execution rate of one or more modules. the fremem parameter is an indication of the amount of free memory (in bytes) available for user configuration. control modules, function blocks diagrams, and sequential function charts all consume configuration memory. it is inadvisable to construct configurations that drive the fremem value to 0. a minimum of 400k is recommended for controller fremem. 控制器的内存随不同型号有所变化，内存总量可能要问emerson了。只要不是md+，那么12m的内存余量应该还是很大的； 76%的freetim也很大； 应该足够用了。 deltav books online 里面的资料很全面，建议楼主多多阅读。查看更多
