9.3.2  Downloading Parameters 
In the working area in NWCONFIG, users can download the routing tables produced to PLCs, the parameters 
related to the PLC Links constructed, and the parameters related to the Ether Links constructed to the nodes. 
The users have to download the routing tables produced to nodes in the working area. 
 
9.3.2.1  Introduction of Parameters 
  Routing table 
The  routing  data  stored  in  a  PLC  is  data  related  to  the  PLC  itself,  and  therefore  the  routing  tables 
downloaded to nodes are different.   
  Parameters related to a PLC Link 
The parameters related to a PLC Link can only be downloaded to the PLC designated as a master station. 
If the parameters related to a PLC Link are downloaded to a slave station, the related special relays and 
the related special registers in the slave station will be restored to the default setting. There is only one 
master station in a network. If users are not sure whether a device was designated as a master station, and 
whether the parameters related to a PLC Link was downloaded to the device, they have to download the 
parameters related to a PLC Link to the device. 
  Parameters related to an Ether Link 
The parameters related to an Ether Link must be downloaded to the data demanding nodes. However, the 
data exchange table stored in a PLC is  a table related to  the PLC itself. Besides, if  the parameters set 
include a node which does not demand any data, the data in the node will be cleared after the parameter 
are  downloaded  to  the  node,  and  the  start  mode  of  the  node  will  depend  on  the  parameters  after  the 
parameters are downloaded to the node. 
 
9.3.2.2  Description of Downloading Parameters 
If the users want to download parameters, the Routing Mode checkbox in the Select a Driver window must be 
unselected. Please refer to section 9.1.3 for more information. 
  Single node 
The users have to select a node in the working area. 
 
 
After the users click Download to PLC on the PLC menu, or    on the toolbar, the Optional Download 
window will appear. The users can also open the Optional Download window by right-clicking the device 
they select, and clicking Download to PLC on the context menu.
