You can use tag groups to help define a subset of tags in the system.
Tag groups are helpful when you want to examine the alarm states for a
subset of tags in the system. See Chapter 5,
, for more
information on alarm groups.
Operations
The operations attributes include when to update the tag value in the
RTDB, whether to log data to a historical file, whether to log events
associated with the tag, and information about the initial value of the tag at
Engine startup. Figure 3-7 shows the Operations Tab of the Analog Tag
Configuration dialog box. With this section of the dialog box, you can
inform the BridgeVIEW Engine of what to do with the data in the RTDB.
