Variable name and alias name

The alias name is an optional parameter that defines an alternative name for a local or global variable. Use the language editor to reference an existing variable using the variable or alias name.
When a variable has an alias name assignment, both the variable name and the alias name appear in the variable grid and variable selector.
In the following example:
  • The variable
    _IO_EM_DO_00
     is assigned an alias name
    Alias_test00
    .
  • The variable
    _IO_EM_DO_01
     is assigned an alias name
    Alias_test01
    .
