For example, if you want to trigger an event for an analog point every 15
minutes, you should set the TE bit every 15 minutes by the ladder logic. But, in
this case, you may not want the state change events to be generated. Then, set
the bit DCE. You can get the timed events every 15 minutes.

For Counter type data, you can configure Threshold information in the
Configuration file. Each element can be configured to the threshold value for
each point. A counter event is generated if the absolute value of the difference
between the present value of a counter point and the value that was most
recently queued as an event for that point exceeds the threshold value that was
configured in this file.

For Analog Input type data, you can configure deadband information in the
Configuration file. Each element can be configured to the deadband value for
each point. An analog input event is generated if the absolute value of the
difference between the present value of an analog input point and the value
that was most recently queued as an event for that point exceeds the deadband
value that was configured in this file.
