13.1 Definition of symbols (mnemonics)
It is a possible to associate a symbol (name) to any PLC resource. It may have up to 8 characters
so long as the name does not coincide with any of the reserved instructions. It may not contain the
following characters: blank-space " ", equal sign "=", parenthesis "(" or ")", comma "," or semi-colon
";".
These symbols or names must always be defined at the beginning of the program. Duplicate
symbols cannot be defined; but several symbols may be assigned to the same resource.
For better clarification, the symbols used in this program are grouped by subjects.
Used in: Basic and necessary programming.
Used in: Treatment of the axis travel limit switches.
Used in: Treatment of the machine reference (home) switches.
Used in: Treatment of M, S, T functions.
Used in: Machine way lubrication.
