16.7 Cautions when many triggers and devices are set
When many points are registered or when many observe status operations are performed as
described below, it takes considerable time until the operations are completed. As a result, the
response time of the GOT may be affected.
• When selecting "Momentary" for "Action" and setting a large number of points for "Storing
device" in "Trigger/Action".

Effect on GOT
• Effect on functions and objects which are actuated at a constant cycle:
Functions which are cyclically actuated may not be executed in accordance with their
setting. For example, the observe cycle, sampling function, alarm history/list function, the
current time function and the trend graph function may be affected.
• Effect on screen data transfer:
When the display is automatically changed to the DATA TRANSFER screen and screen
data is transferred, the error message may be displayed in the screen creation software.
In such a case, changeover the display to the DATA TRANSFER screen by key operation.
Then, screen data can be sent and received.
• Effect on the monitoring function, screen changeover function and key operation:
Specified operation may be delayed for screen changeover, monitoring and key operation in
the same way described above.
• Effect on the built-in 2-port interface function:
When circuit monitoring, device batch processing or monitor registration is executed in a
peripheral unit, a communication error may occur in that unit.
