Note. If the first controller communication is connected using SSCNET III/H in the factory setting, the operation mode will be fixed to "J4
mode". If the communication is connected using SSCNET III, the mode will be fixed to "J3 compatibility mode". To return to the
factory setting or to select an arbitrary mode, change the setting with the application "MR-J4(W)-B Change mode" or "MR Mode
Change".
The application "MR-J4(W)-B Change mode" or "MR Mode Change" are available with MR Configurator2 Version 1.12N and
later. When a version older than 1.12N is used, download an update version from the MITSUBISHI ELECTRIC FA Global
