9.1.1 Display options: suppression filter
Function
The purpose of masking filters is to selectively reduce the number of
displayed machine data. For this function, all machine data in areas
· General machine data
· Channel-specific machine data
· Axis-specific machine data
· Drive machine data
are assigned to specific groups (e.g. configuration data, etc.).
The following applies:
1. Each area has its own group organization.
2. Each group corresponds to one bit in the filter word ("spare" bit in
previous SW).
3. Each area has a maximum of 13 groups (group 14 is reserved for
Expert mode (see below), bit 15 is reserved for expansions).
From SW 6.4 group allocation is implemented for display machine
data. For more information, see display machine data filter.
Filter criteria
The following table shows the criteria for displaying machine data in
the order in which they are evaluated:
Criterion Test
1. Access rights If the level of access authorization is not sufficient, the MD is not displayed.
Otherwise criterion 2 is checked.
2. Suppression filter active The MD is always displayed when the filter is not active.
Otherwise criterion 3 is checked.
3. Expert mode The MD is not displayed if expert mode bit is set
and expert mode is not selected.
Otherwise criterion 4 is checked.
4. Groups If at least one group bit is both set and selected
in the suppression filter, criterion 6 is checked.
Otherwise criterion 5 is checked.
5. All others If none of the group bits is set and "All others" is
selected in the masking filter, then criterion 6 is checked.
If none of the group bits is set and "All others" is
not selected in the masking filter, then the MD is not displayed.
