Compiler Output

If the previous step was accomplished, the compiler performs the actual compilation, and then prints a report in the Output window. The last string of the report has the following format:m warnings, n errorsIt tells the user the outcome of compilation.

Condition	Description
n>0	Compiler error(s). The PLC code contains one or more serious errors, which cannot be worked around by the compiler; the binary output file is not generated, the project cannot be downloaded.
n=0, m>0	Emission of warning(s). The PLC code contains one or more minor errors, which the compiler automatically spotted and worked around.However, you are informed that the PLC program may act in a different way from what you expected: you are encouraged to get rid of these warnings by editing and re-compiling the application until no warning messages are emitted.Even if you do not correct the warnings, the binary output file is generated and you can download the project.
n=m=0	PLC code entirely correct, compilation accomplished. You should always work with 0 warnings, 0 errors.The binary output file is generated and you can download the project.
