    CNC option

    This function need the following CNC option.

      The PROFIBUS-DP master function is necessary.

    For HSSB connection,

      The extended driver/library function is necessary.

    For Ethernet connection,

      The Ethernet function and the extended driver/library function are necessary.

      However, in case of Series 16i/18i/21i-B, 0i-B/C, the required CNC option is as follows.

      When Embedded Ethernet is used,

        above two optional functions are not required.

      When Ethernet board is used,

        only Ethernet function is required.

    CNC parameter

    This function is not related to CNC parameter.

    CNC mode

    This function can be used in any CNC mode.
