3. Select a scan class and fill in a foreground and background period.
The period specifies, in seconds, how often the programmable
controller address is scanned when its value is required by a
foreground or background component. The foreground period
applies to graphic displays and the tag monitor. The background
period applies to any component that performs a continual
background activity, such as derived tags, events, alarms, and data
log.
To specify a period, type a number. You can use fractional seconds.
For example, if you type .6 the address is scanned every six tenths
of a second.
4. To save the configuration for a scan class without closing the
editor, select another scan class.
5. When you finish configuring scan classes, click OK.
Monitoring communications
Use any of the following methods to monitor communications:
Activities—In the Activity Log Setup editor, ensure
communication errors, warnings, and remarks are enabled and are
set up to log to the log file and activity bar. At runtime,
information appears in the log file and activity bar, indicating any
problems.
Communication status—Ensure communication status is turned
on, otherwise communication errors will not be logged to the
activity log file or activity bar (even if they have been configured to
do so in the Activity Log Setup editor). By default, communication
status is turned off until you run the project. To turn
communication status on, use the ComStatusOn command.
