...
(1) Alarm Type
Select the analog alarm condition among three types.
Item | Description |
Value | The alarm occurs according to the analog tag value’s boundary value. |
Deviation | The alarm occurs according to the assigned target value and the difference between the tag value and target value. |
ROC | The alarm occurs according to the rate of change in tag value. |
(2) Alarm Configuration
Item | Description |
Enable | Enable or disable the alarm operation. |
Hysteresis | When the analog value changes around the setting value, it may cause the repetitive occurrence of the alarm. To prevent this situation, assign the sensitivity of the alarm. The alarm will occur only when the value exceeds the setting value and the hysteresis value. Also, the alarm will be cleared only when the value is less than the hysteresis value subtracted from the setting value. |
Delay-Time | You may assign the delay time of the alarm in seconds. If the alarm is turned OFF in the delay time, it is not assumed as an alarm. You can assign from 0 to 99999.9 seconds. |
Level | Assign the alarm level. You can assign from 1 to 15 grade. (In case of CIMON-SCADA Version lower than 3.04, 1 to 8 grade) In the [Alarm Configuration] window, you can output the specific alarm according to the level. |
Zone | Assign the location of the digital alarm. You can assign the alarm zone from A to P. In the [Alarm Configuration] window, you can output the specific alarm according to the alarm zone. |
The tag value has changed from the Lo area to normal area as shown below. However, since the value did not exceed the hysteresis value, the alarm state does not change.  In the figure shown below, the tag value has changed from the Hi area to the normal area. Since the value exceeded the hysteresis value, the Hi alarm will be cleared.  |
