5.3.4 Register Specification Methods

Registers can be specified directly by register number or by symbol (register name) specification. A combination
of both of these register specification 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.
