5.3.4 Register Designation
Registers can be specified directly by register number or by symbol (register name). A combination of both of these
register designation methods can be used in ladder programs.
When using the symbol specification method, the relationship between symbols and register numbers must be defined.
The following table shows the register specification methods.
