与组态时不同,调试时可显示I/0变量的实时值以及数
字信号的实时状态(0或1),例如FBD图中数字信号线的外形变化(实
线或虚线)就反映其状态。过程变量的当前值可同时反映在数值窗口
与趋势窗口中,为功能测试与调整提供了极其方便的手段。不仅可显示当前调出程序的1/0变量,而
且能够显示来自其它程序变量和中间变量的实时值。
可以在调试过程中修改参数以实现程序优化设置,调试者可决定修改是临时的或永久性的。通过
参数.上载可浏览某段时间所做的修改,并进一步选择存储那些永久性参数以保证冷启动时不会丢失。
输入输出强制及设定新值功能用于动态仿真目的。
BF (Control Builder F)的组态方式与调试方式之间的简单切换使得应用程序的修改十分容
易。下载程序时可选择下载全部或局部组态,故当系统在线(保持运行并与实际生产过程相连)而又必
须修改控制方案时,CBF 可以进行在线组态而不必停车。
