Set up connections
Up to 8 connections to so-called logical drives (data carriers) can be configured. These
drives can be accessed in the "Program manager" and "Startup" operating areas.
The following logical drives can be set up:
● USB interface
● CompactFlash Card of the NCU, only for SINUMERIK Operate in the NCU
● Network drives
● Local hard disk of the PCU 50.3, only for SINUMERIK Operate on the PCU
Software option
In order to use the CompactFlash Card as data carrier, you require the option
"Additional 256 MB HMI user memory on CF card of NCU" (not for SINUMERIK
Operate of PCU50 / PC).
Note
The USB interfaces of the NCU are not available for SINUMERIK Operate and therefore
cannot be configured.
