Configuring the HMI system
2.3 Connecting network drives
For the Machine area:
$MM_USER_CLASS_DIRECTORY1_M (9516)
$MM_USER_CLASS_DIRECTORY2_M (9517)
$MM_USER_CLASS_DIRECTORY3_M (9518)
$MM_USER_CLASS_DIRECTORY4_M (9519)
The display machine data for access authorizations are activated immediately, i.e., after
switchover to the respective application, while a change in directories takes effect only after
a restart.
Error messages
The configured network drives are evaluated when HMI-Advanced boots. This evaluation
does not check whether the connection actually exists. This check is made after the drive is
selected by the operator. If the configured path cannot be accessed, an error message is
issued.

2.3.3 Connecting logical drives
Requirements
The "logical drives" softkey is available from access level 2 onwards (Service):
This is the reason that a machine operator cannot use this function, but instead only a
service technician. A restart of HMI-Advanced is necessary to update the assignment of the
softkeys.
With this softkey you can configure access to USB storage media on USB interfaces or PCU
and TCU and to network drives (option) in the Programs, Services, or Diagnostics operating
areas.
Function
The control can be connected to external network drives or other computers. This makes it
possible, for example, to execute part programs from other computers.
Two alternatives are available:
● In the setting screen "Logic drives" under "Start-up" → "NC".
● By configuring file LOGDRIVE.INI.
