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.
In SW V6.3 and higher, the variable lists ncv*.mdb are separated according to:
NC variables including machine and setting data:
Machine data for 611D drive:
Machine data for 611D linear drive:
Machine data of the 611D drive, Performance 2:
Machine data of the 611D linear drive, Performance 2:
Machine data of the hydraulic drive:
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).
