Data Match:
The value of the register is equal to the alarm value.
Data Mismatch:
The value of the register is not equal to the alarm value.
Absolute High:
The value of the register exceeds the alarms value.
Absolute Low:
The value of the register falls below the alarms value.
Deviation High:
The value of the register exceeds the setpoint by an amount equal to or greater than the
alarms value.
Deviation Low:
The value of the register falls below the setpoint by an amount equal to or greater than the
alarms value.
Out of Band:
The value of the register moves outside a band, equal in width to twice the alarms value and
centered on the setpoint.
In Band:
The value of the register moves inside a band, equal in width to twice the alarms value and
centered on the setpoint.
Rate of Change:
The value of the register changes within given Time Window by the specified amount of
Change Limit.
Scaling:
Transform an input register from one range of values to another range.
Bit Operations:
Transform a set of DI/DO values between bit locations of an AI/AO register.
Calculations:
Perform basic math functions between registers.
Alarm Value (Required):
Value at which the alarm will trigger.
If the Event Type is a Data Match or Data Mismatch type, the alarm will trigger on this exact value. In all other
cases, the data source must exceed this value (above or below depending)
This must be within the limits of the data source.
For IODB, these limits are:
Activation Delay (in sec) (Required):
The Activation Delay is used to indicate how long (in seconds) the
alarm condition must exist and be true before the alarm will become active.
For example, if the alarm is configured to go active when an input register is an Absolute High exceeding 1000,
then the register value must stay above 1000 for the activation delay period, or else it will be ignored.
Clear Event/Alarm Condition:
Select the desired option to clear an event condition.
Automatic:
Allows an event condition to clear to an inactive state when the input meets configured
conditions.
Manual:
Requires a user to login and clear the event. An event that is not cleared will continue to generate
actions if it is level triggered. If the action is edge triggered, and this event is not cleared, then no new
event action will result.
