Tag Detail3-4 SIMATIC PCS 7 OSx 4.1.2 Operator
Tag Detail Displays (continued)
While the system is in the Operate state the operator needs to interact with
the controller; for example, to change a setpoint, adjust alarm limits, enable
or disable alarms, or start or stop a pump or motor. An operator who has the
appropriate security privileges and process group membership can do this
by entering new values in a tag detail. Figure 3-2 shows a typical tag detail
display.
On the tag detail, the shadowed or indented boxes indicate values that the
operator can change. Click the box to bring up a command form at the
bottom of the screen (Figure 3-3).
NOTE: If the operator displays a command form for one of the tag details,
makes a change to a field, and the change does not succeed, the value in the
database does not change. However, the command form continues to display
the new value that the operator attempted to enter. The tag detail continues
to display the correct, unchanged value. When the operator redisplays the
command form, it contains the original, unchanged value.
