Maintaining a network of data loggers deployed across multiple locations can be challenging. Individual data logger programs may be similar, but often differ in variables, measurements, and data tables. When these sections grow large, it can become difficult to quickly scroll to key parts of the program—such as the main scan. By creating reusable code libraries, you can use the CRBasic IncludeSection() instruction to move variables, measurements, and data tables into separate library files. This keeps the main program concise and makes it much easier to navigate directly to the main scan. It also greatly simplifies updating and maintaining the entire network. This video demonstrates how to use the IncludeSection() instruction to streamline a CRBasic program and verify proper operation once the information from the code library is imported.
