U16 PASCAL_ECAT_Slave_DIO_Set_Output_Value (U16 CardNo, U16 NodeID, U16 SlotNo,
U16 Value)

Purpose
This is for setting the output status of the DO module. To output the status of Y15, Y14, …, Y1,
Y0 (from left to right), users can convert the bit status to decimal format.


Example
U16 Status;
U16 CardNo=16, NodeID=1, SlotNo=0;
U16 Value=0xFFFF;
