Return

EW_OK is returned on successful completion, otherwise any value except EW_OK is returned.

The major error codes are as follows.

Return code Meaning/Error handling
EW_NOOPT
(6)
No option
  • The PROFIBUS-DP board(hardware) is necessary.
  • The PROFIBUS-DP control software is necessary.
  • The PROFIBUS-DP master function is necessary.
  • The extended driver/library function is necessary.
  • EW_VERSION
    (-7)
    Version of PROFIBUS-DP control software is wrong.
    This function was called by version 08 of the control software. Exchange the control software besides the version 08.

    As for the other return codes or the details, see "Return status of Data window function"

    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.
