如果摄像机未就绪，则无法获取图像。这意味着如果 I/O 参数 "就绪 "设置为 "0 "或 "假"，则无法使用获取图像等摄像机功能。
如果在 AS 中将摄像机的图像触发参数 (ImageAcquisition) 强制设置为 "1"，也无法触发图像采集。当该参数的值从 "0 "变为 "1 "时，图像将被触发。
Question: What should I do if the image shown in the HMI application is not updated?
If the camera is not ready, images cannot be acquired. This means that if I/O parameter "Ready" is set to "0" or "False", camera functions such as acquiring images cannot be used.
Nor is it possible to trigger an image acquisition if the camera's image trigger parameter (ImageAcquisition) is forced to "1" in Automation Studio. An image is triggered when the value of this parameter is changed from "0" to "1".
