Protection levels are identified by numbers and are used to enable data areas.
A more detailed explanation can be found in the next section: Protection level
concept.
The unit refers to the default setting for the machine data:
S
MD_$MN_10220_SCALING_USER_DEF_MASK (activates the scaling
factors)
S
MD_$MN_10230_SCALING_FACTORS_USER_DEF (scaling factors for
the physical variables)
S
MD_$MN_10240_SCALING_SYSTEM IS METRIC=1 (basic system is
metric)
If the MD is not based on any physical unit, then the field contains a "–".
This value is used to set the machine or setting data to its default.
Note
On the HMI, input is limited to 10 digits plus decimal point and sign.
