- The I/O Label Editor shows all available I/O types on your controller.

CAUTION
When you specified the string (SPEL+ commands and so on) that has other roles in Epson RC+ 8.0 as a label, it may have unexpected consequences. Specify a unique label name so that it does not duplicate with those strings.
If you set a keyword, the following dialog will be shown.
