Programming 4.1 PC295 PC295 software is a freeware utility provided by Campbell Scientific Australia to write programs for the DataView II. PC295 first reads the datalogger program, to generate the list of Public Variables and to determine the scan rate of the datalogger.
DataView II (CD295) Dual Line Display 2. Once the PC295 program starts you will see the main screen. 3. The first step in creating a DataView II program is to select ‘Create new DataView2 Program’ from the File menu. This will open a file browser window which will allow you to locate the datalogger program (with CR1, CR2, CR3, or CR8 extension). When the correct datalogger program is selected, click Open.
DataView II (CD295) Dual Line Display 4. If you have chosen to ‘Create a new DataView2 program’, a file browse window will appear. To operate correctly, your DataView II needs some information about the program running in the datalogger to which it will be connected. PC295 reads the datalogger program file you select at this step, and extracts information such as the Scan Interval and the list of Public variable names. Locate the datalogger program and select Open.
DataView II (CD295) Dual Line Display 5. PC295 will now return to the main screen, however the ‘CRX FileName’ and ‘DataView 2 Refresh Rate’ will no longer be blank. PC295 has read your datalogger program, and is now ready for you to create a DataView II program. Select the ‘Add Screen’ button. ‘Variable to Display’ has a drop-down list, from which you are able to choose a Public Variable used in the datalogger program. 6.
DataView II (CD295) Dual Line Display If the variable you have chosen is not floating point, the ‘Display Options’ panes on the right side of the screen will provide multiple options for displaying the variable. The example below shows the Display Options for a Boolean variable. Long integer data types are used to store both integer whole numbers and time stamps. Choose ‘Numeric’ for the Display Option if your long integer variable is a whole number.
DataView II (CD295) Dual Line Display 7. If at any time you would like to return to an earlier screen, you can do so by using the ‘Screen Number’ drop down. Also, if you would like to delete a screen you can select the screen you would like to delete from the ‘Screen Number’ drop down and click the ‘Delete Screen’ button. 8. After entering all of the screens in your DataView II program, you will probably want to save your work.
