5.2.4 Establishing Information Properties
General Different types of information contain different types of properties. To view the proper-
ties associated with a specific information unit (indication, command, etc.), position the
mouse on the specific row under
,QIRUPDWLRQ
, and then use the right mouse button
to access a context menu where
3URSHUWLHV
can be selected.
For example, if the cursor is positioned on a specific output indication, the right mouse
button is pressed, and the menu item
3URSHUWLHV
is selected, then a choice of
whether the indication should appear in the oscillographic fault records (Figures 5-10,
5-11, and 5-12) is presented. For internal single point indications, the default status of
the indication (on, off, or undefined) after device reset can be selected as well (Figure
5-11).
