PMC_PRFWRSLVPRM | PROFIBUS

Description

Writes the slave parameter of the specified slave number.

This function is available at the version 01-07 and 09 or later of the PROFIBUS-DP control software(6557 Series). In the control software in the version 08, the return value becomes EW_VERSION.
When the parameters are changed, the restart of CNC is required for putting the change into effect.
This function is unavailable at the 6558 Series.

* Please refer to "PROFIBUS-DP function manual" for details of the PROFIBUS-DP 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,
