About the DVC write status display function
The DVC write status display function is a function for displaying the success or failure of a write
operation on the PLC when writing program data to the driver controller EEPROM when in DVC
mode.
A successful write is displayed in the RX50 to 5F area, while a failed write is displayed in the
RX40 to 4F area.
◦ About the DVC function
The DVC function is a function for sending DVC data to only the specified ID.
Setting driver controller ID 0 to F in RY60 to 6F and pressing the DVC switch allows DVC data to
be sent to only the specified ID.
