This function allows you to enable or disable writes to parameters in your product. In other words, this allows channels to act as read-only channels. You would typically not need to use this function because the channel read/write privilege would have been set in MB_CfgCh().
void MB_WrEnSet (MODBUS_CH *pch,
CPU_INT08U wr_en)Arguments
