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 STEP7 source file (.awl) and
stored.
Once he has generated a PLC data block by means of the STEP7 compiler, the programmer
is able to read or write NCK variables via the basic program function blocks "PUT" and
"GET" using the STEP7 file.
The list of selected variables is also stored as an ASCII file (file extension .var).
