System variable Type Meaning
$P_IS_EES_PATH[ <n>] BOOL Interrogates whether the path supplied by $P_PATH[<n>] or
the program name supplied by $P_PROG[<n>] corresponds to
the NC notation or the EES notation.
= FALSE $P_PATH[<n>] and $P_PROG[<n>] supply a NC
notation. This means that each identifier has the
prefix "_N_". The separator for the file identifier is
"_".
Examples:
● Path in the NC notation: "/_N_WKS_DIR/
_N_MYWPD_WPD/"
● Program name in the NC notation:"_N_MY‐
PROG_MPF"
A path in the NC notation can refer to the passive
file system in the NC as well as also the global part
program memory.
= TRUE $P_PATH[<n>] and $P_PROG[<n>] supply an
EES notation. This means that the identifiers do
not have the "_N_" prefix. The separator for the file
identifier is ".".
Examples:
● Path in the EES notation: "//DEV1:/WKS.DIR/
MYWPD.WPD/"
● Program name in the EES notation: "MY‐
PROG.MPF"
<n>: Index <n> defines the program level, from which the path information should be read (value range:
0 ... 17)
Note
In the EES mode, outside the global part program memory (GDIR), system variables
$P_PROG, $P_PATH and $P_PROGPATH path names in the EES notation. For the EES
mode, user programs that evaluate and process these path names must be extended so that
they can also process pathnames in the EES notation.
3.4.2 Working memory (CHANDATA, COMPLETE, INITIAL)
Function
The working memory contains the current system and user data with which the control is
operated (active file system), e.g.:
● Active machine data
● Tool offset data
● Zero offsets
● ...
