The creation of the LD network is followed by compiling the project and correcting all errors that are detected by the compiler or the linker. For compiling, the MULTIPROG® command 'Make' is used.
Creating optimized machine code
Compiling means translating the contents of the worksheets into specific machine code which can be executed by the PLC. While compiling the project, the message window shows you the compilation process.
Any detected errors and warnings due to syntax errors, memory or file problems are logged and displayed in the message window. By doubleclicking on an error message you directly jump to the location of the error in the respective code body worksheet or the variable declaration.
After successful compilation we can send the project to the target system (see stage 4).
