Function and call interface - UA_WriteList
Function of the block
With the block you write data to the connected UA server.
You program the attributes to be written in a UDT "UANodeAdditionalInfo" that is referenced
by the input parameter "NodeAddInfos".
The handles required at the input parameter "NodeHdls" are read from array of the output
parameter "NodeHdls" of the "UA_NodeGetHandleList" block.
The number of nodeIDs at the input parameter "NodeIDCount" is always 1 so you need to
call the block separately for each target node.
