Checking and Compiling a Program
 
After users write a program, they can check the syntax of the programming language or compile the program. 
The syntax and the structure in the present window will be checked after the Check function is enabled. The 
whole project will be checked after the Compile function is enabled. If there is no error in the project, an 
execution code will be generated automatically. After the program is compiled successfully, the mother line at 
the left side of the ladder diagram will become black.

the system will automatically lead users to the place where the error occurs. The users can enable the Check 
function or the Compile function after the error is eliminated.
