The protection levels for user data are set in machine data 9200 to 9299.

vices” menu via an input display.
3.9.2 Language default
To be able to switch between the two configured languages even when the op-
erator is not familiar with the selected language, the switchover between the
languages must be performed “blindfolded”:
1. Select menu bar.
2. Select “Start-up” (3rd horizontal softkey from right).
3. Switch to the highest level with RECALL.
4. Select “Change language” (3rd vertical softkey from top).
One of two languages can be called alternately in the MMC100. These are de-
fined while the MMC software is being loaded. While the control is in operation,
the operator can switch between these two languages only by selecting the
softkey “Change language” in the “Start-up” display.
On the MMC102/103 there are several methods of switching over between lan-
guages while the control is in operation:
S Switchover between two preset languages.
S Online change of the second language.
The selectable languages are set and managed in a file. When the language is
switched in online operation, the first language remains as originally set and
only the second language can be changed.
The vertical softkey labeled “Change language” in the “Start-up” display is used
to switch between two languages. The switchover takes effect immediately. This
key can only be used to switch between two predefined languages.
