Figure 13-19 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 following ncv*.mdb variable list is available:
Variables
NC variables including machine and setting data:
Parameters of the 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.
After generating 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).
The variable list supplied with the "NC VAR selector" tool is adapted to the current NC software
version. This list does not contain any variables (GUD variables) defined by the user. These
variables are processed by the function block FB5 in the basic program.
Note
The latest version of the "NC VAR selector" is capable of processing all previous NC software
versions. It is, therefore, not necessary to install different versions of the "NC VAR selector"
in parallel.
