Important notes on MCU settings

If you download a program without MCU data to a PLC to which you have downloaded a program with MCU data before, the setting data will be deleted.

• The MCU setting data is stored in the compiled code in the same way as in the system registers.

• With the FP2, system register No.2 should be set to 2 or higher.

• The MCU data is retained even when you change the PLC mode from PROG to RUN or turn off the power while the PLC is in RUN mode.
