Speaking of Pi-based software development, there are two main aspects, 1: Using piapi to directly operate pi. The advantage of this method is high efficiency and easy control of any operation. The disadvantage is that you need to purchase piapi. The following describes this method in detail; 2: Access PI through the OPC communication protocol agreed by the International Industrial Organization. The advantage of this method is that it is common, be

Yesterday, the beta version of 3.5 was already supported by the 2007 Open XML Format (DOCX,PPTX,XLSX) for POI. Need to join Poi-ooxml-3.5-beta6-xxxx.jar. But the Poi-ooxml-3.5-beta6-xxxx.jar package requires several packages under the Ooxml-lib directory to run. The code is as follows Import java.util.ArrayList; Import Java.io.File; Import Java.io.FileInputStream; Import Org.apache.poi.hwpf.extractor.WordExtractor; Import Org.apache.poi.xwpf.extractor.XWPFWordExtractor; Import Org.apache.poi.

online mode, project engineers can test and monitor communication between devices. From a technical point of view, Simaticimap has the following advantages: • Communication between software components, that is, communication between technical function templates can be defined in Simaticimap through a graphical interconnect. No programming knowledge required. • Consistent data for communication is generated based on engineering information and is downloaded to the device. The communication betwe
