Activating the function
Software option
To use this function together with the user memory (100 MB) on the CompactFlash
Card, you require the software option
"CNC extended user memory."
If you use a PCU with this option, the entire memory area of the storage medium is at your
disposal, e.g. of an SSD.
If you use SINUMERIK Operate with an NCU and also have the option "Additional HMI-
Us.memory on CF card of NCU", you can expand this memory to 6 GB.
Software option
To have unlimited use of this function, you require the software option
"Execution from External Storage (EES)."
Note
The EES function makes EXTCALL calls superfluous. If required, existing EXTCALL calls can
be converted. EXTCALL calls without conversion are also executed for an active EES, although
still as EXTCALL.
A detailed description of the EES function is provided in the following documentation:

5.4 Creating a global part program memory
With the global part program memory (GDIR), a structure is provided analog to the passive
file system of the NC. It is integrated in the search path of the NC for subprogram calls. If you
create a GDIR, all participants in the system have access to the same logical drive. The
participants can directly execute part programs from the common program memory. The GDIR
so replaces or extends the part program memory of the NC.
Note
The global part program memory plays a role only for the EES function. The creation of a GDIR
is, however, not essential for the EES operation.
