PLC program.

The PLC program may combine several files in mnemonic language (extension: "plc"),
several files in "C" language (extension: "c") and a file in contact (ladder) language (extension
"ld"). All the files making up the PLC program must be in the folder \MTB \PLC \PROJECT.
It is recommended to use the mnemonic language files or the contact (ladder) language files
as the main PLC program and the "C" language files for auxiliary tasks (for example,
temperature compensation).
Subroutines in the PLC program.
The subroutines of the program in mnemonic or contact (ladder) language must be defined
outside of the modules, for example at the end of the program after the END instruction.
The subroutines of the "C" language file must be defined as external at the beginning of the
mnemonic language program (extension: "plc") or contact (ladder) language program
(extension "ld"). The name of the subroutine must be written in capital letters in both files.
"C" language programming offers a math library (trigonometric, logarithmic, etc.) that allows
performing operations with tables, arrays, float type variables, etc.
