330104-00-05-10-02-CN hides the underlying communication process in a data acquisition (some devices need more than one sending and receiving process to complete an acquisition, such as Siemens S7200); encapsulates the dynamic acquisition algorithm for the scattered acquisition points; encapsulates the commonly used command operations; and provides a unified interface for the interaction with the monitoring system; the PLC driver encapsulates the underlying communication process and only exposes the interface method to the outside. The PLC driver encapsulates the underlying communication process and only exposes the interface method to the outside, so that the developers can call this method in a unified way, thus ensuring the transparency of the software to the customers, detaching the developers from the low-level development and reducing the difficulty of development.

330104-00-05-10-02-CN In this case, the user wants to utilize as much physical bandwidth as possible to ensure the fastest possible acquisition speed and updates. In this mode, the ideal state is that the device is always in the acquisition state. Acquire the channel with the smallest cycle time away from the required acquisition of all currently active channels. All channels are guaranteed to be available for acquisition, but the CPU usage will be higher in this mode compared to the other modes.

330104-00-05-10-02-CN In the case where the communication link needs to be controlled, for example, the user uses GPRS for acquisition and is billed by flow rate, so a large amount of communication is not possible. At this time, by setting the acquisition mode to on-demand acquisition, and then call the interface function to start a single acquisition when needed. Otherwise, no data acquisition will be performed, and the acquisition frame is a compromise between CPU occupancy and acquisition speed to ensure that channel acquisition will be performed within the time set by the user for the channel refresh cycle, and then the next acquisition will be performed until the refresh cycle of the next channel arrives.
