How to Use CUBLOC Studio
After installing Cubloc Studio and executing it, you will see the following screen.
You will see that, at first, Cubloc Studio will default to the BASIC editor.
If you press F2, the screen will change to the Ladder Logic editor and if you press F1, it will switch back to the BASIC editor.
Source files are saved as two files under the file extensions .CUL and .CUB. If you need to backup or move source files, you must keep BOTH of these files together.
When opening a file, you will only see .CUL files. (.CUB files are not displayed, but they are in the same folder). When you open a .CUL file, Cubloc Studio automatically opens CUB file.
The source code can only be saved on the PC. Source code downloaded to the Cubloc module can not be uploaded back to the PC.
When you press the RUN button (or CTRL-R), Save, Compile, Download, and Execute are all automatically processed.
Ladder Logic and BASIC both are compiled with one RUN button. If an error is found during compilation, the cursor will relocate to the error position.
IMPORTANT: All Cubloc modules implement code obfuscation. By obfuscating the downloaded program data, the code is safe from any attempt to read part of the chip’s memory and copy the source code.
Creating BASIC Code
You can create BASIC code as shown below. Cubloc Studio's text editor is similar to most text editors, and performs syntax highlighting of certain commands.
