Auto SDO Configuration: After users click Auto SDO Configuration in the Node 
Configuration… window, the Auto SDO Configuration window 
will appear. If the users click Add, they can add an automatic 
SDO. If the users click Edit…, they can modify the automatic 
SDO selected. The maximum number of automatic SDOs which 
can be assigned to a slave station is 20. An automatic SDO can 
only write parameters, and can not read parameters. It writes 
parameters to a slave station once only when the slave station is 
ready to operate for the first time. 
 
After the users click Add, the Add New SDO window will appear. The index in the Index 
(hex) box is the index of the parameter which will be accessed, and the subindex in the 
Sub-Index (hex) box is the subindex of the parameter which will be accessed. The length in 
the Length (dec) box is determined by the data type of the parameter which will be 
accessed. A byte is a unit of measurement for length. The users can click 
, and select 
an object in the object dictionary defined by the EDS in the slave station selected. After the 
users click OK, the software will automatically bring out an index, a subindex, and a length.
