That was basically our procedure for loading software form old and onto new programable controllers when they needed to be replaced. The dedicated loading software was in Japanese, so none of us actually knew what steps we were performing, just Enter, Enter, Left-Arrow, Down-Arrow, F10, Type "RReg" (no quotes), Enter, Enter.... The only way you knew it work was if the equipment came up again. That went on for a few years then we finally got an English version of the dedicated loader. That went on for about 7 years then we finally got a general PLC software development package (GX Developer).
