After defining the tags, you also need to make the mapping between the Name and the File
Number.
Note 1 The file number should be unique, i.e., the same file number cannot be mapped on the different

2 The file number available to be supported ranges from 0 to 254.
The mapping of the above-mentioned items with NB-Designer addresses is shown as the follow-
ing table.
Name Data Type Support Range File Number NB-Designer Address
a INT[255] 0~254 0 INT 000000~000254
s REAL[255] 0~254 1 REAL 001000~001254
b BOOL[1024] 0~999 254 B_BOOL 254000~254999
