(F) Analog Input Alarm Settings
The OME-ET-7000/OME-PET-7000 modules feature a built-in alarm function. The
alarm includes two parts, the high alarm and the low alarm and each need to be
configured for a specific channel.
Value: You can define both the high alarm value and the low alarm value using
the Alarm Value text box. When the analog input value is higher than the high
alarm value, or lower than the low alarm value, an alarm occurs. The alarm
status will then be activated and switched to on.
Enable: Each analog input alarm can be switched to on or off by clicking the
appropriate radio button.
Mode: The OME-ET-7000/OME-PET-7000 allows the alarm to be selected as
either Momentary or Latch mode, which can be set using the Mode combo box
for both the low alarm and the high alarm.
Latch Mode: Once an alarm occurs, the alarm status will be activated and set
to the logic high level. This value will remain until the alarm is cleared manually.
Momentary Mode: In this mode, the alarm status will dynamically change
depending on whether or not an alarm has occurred. If an alarm occurs, the
alarm status will be set to on. If the alarm is deactivated, the alarm status will be
set to off.
