Figure 13-20 NC VAR selector
After the "NC VAR selector" application has been started, select a list of variables of an NC variant (hard disk →
file Ncv.mdb) to display all the variables contained in this list in a window.
The variable list ncv*.mdb is separated on:
The user can also transfer variables to a second list (separate window). This latter selection of variables can then
be stored in an ASCII file or edited as a STEP 7 source file (.awl) and stored.
Once he has generated a PLC data block by means of the STEP 7 compiler, the programmer is able to read or
write NCK variables via the basic program function blocks "PUT" and "GET" using the STEP 7 file.
The list of selected variables is also stored as an ASCII file (file extension .var).
