Alarm and event histories are kept separately.
Level Detection
Level detection is used to take a level when an alarm or event is generated and switch screens to the
specified screen for the alarm/event with the highest priority. If multiple alarms or events occur at the
same time, the display is automatically switched to the screen for the alarm/event with the highest pri-
ority.

Rise Trigger Detection
Rising trigger detection is used to detect the start of the alarm/event and switches screens. If multiple
alarms or events occur at the same time, the display is automatically switched to the screen for the
alarm or event with the highest priority. If an alarm or event with lower priority than an existing alarm or
event occurs, the screen will not be switched.
If alarms or events with the same priority level occur at the same time, the screen switching will start
from the alarm or event with the lower number set under the alarm event setting (PT - alarm/event set-
ting).
