Event Type

Data Type

Description

Change of Bitstring

Bitstring

Generates an off-normal transition when the value of the referenced property is equal to one of the user-defined Bitstring Values (List Elements after applying the Bitmask) and the values are equal for the amount of seconds defined by the Time Delay parameter. The Bitmask defines the bits important for monitoring.

Change of Character String

String

Generates an off-normal transition when the value of the referenced property is equal to one of the values in the List of Values (List Elements) and the values are equal for the number of seconds defined by the Time Delay parameter.

Change of State

Bool, Byte, Enum, Long, Short, Ulong, Ushort

Generates an off-normal transition when the value of the referenced property is equal to one of the values in the List of Values (List Elements) and the values are equal for the number of seconds defined by the Time Delay parameter.

Change of Value

Bitstring, Float

Generates a normal transition when the value of the referenced property changes by an amount equal to or greater than the referenced property increment (Change of Value [COV] Increment) for the number of seconds defined by the Time Delay parameter.

Command Failure

Bool, Byte, Double, Enum, Float, Long, Short, Ulong, Ushort

Generates an off-normal transition if the values of the referenced property and the Feedback Reference are not equal for a time greater than the number of seconds defined by the Time Delay parameter.

Double Out of Range

Double

Generates a transition to high limit alarm if the value of the referenced property is higher than the range of values determined by the High Limit for a time greater than the number of seconds defined by the Time Delay parameter. This event type accepts a double data type.

Generates a transition to low limit alarm if the value of the referenced property is lower than the range of values determined by the Low Limit for a time greater than the number of seconds defined by the Time Delay parameter. This event type accepts a double data type.

Floating Limit

Float

Generates a transition to high limit alarm if the value of the referenced property is higher than the range of values determined by the current values of the Setpoint Reference, High Limit, Low Limit, and Deadband for a time greater than the number of seconds defined by the Time Delay parameter.

Generates a transition to low limit alarm if the value of the referenced property is lower than the range of values determined by the current values of the Setpoint Reference, High Limit, Low Limit, and Deadband for a time greater than the number of seconds defined by the Time Delay parameter.

Out of Range

Float

Generates a transition to high limit alarm if the value of the referenced property is higher than the range of values determined by the current values of the High Limit and Deadband for a time greater than the number of seconds defined by the Time Delay parameter. The high limit value may be True, False, or an analog value.

Generates a transition to low limit alarm if the value of the referenced property is lower than the range of values determined by the current values of the Low Limit and Deadband for a time greater than the number of seconds defined by the Time Delay parameter. The low limit value may be True, False, or an analog value.

Signed Out of Range

Float (positive or negative)

Generates a transition to high limit alarm if the value of the referenced property is higher than the range of values determined by the current values of the High Limit and Deadband for a time greater than the number of seconds defined by the Time Delay parameter.

Generates a transition to low limit alarm if the value of the referenced property is lower than the range of values determined by the current values of the Low Limit and Deadband for a time greater than the number of seconds defined by the Time Delay parameter.

Unsigned Out of Range

Float

Generates a transition to high limit alarm if the value of the referenced property is higher than the range of values determined by the current values of the High Limit and Deadband for a time greater than the number of seconds defined by the Time Delay parameter.

Generates a transition to low limit alarm if the value of the referenced property is lower than the range of values determined by the current values of the Low Limit and Deadband for a time greater than the number of seconds defined by the Time Delay parameter.

Unsigned Range

Byte, Ulong, Ushort

Generates a transition to high limit alarm if the value of the reference property is higher than the range of values determined by the High Limit for a time greater than the number of seconds defined by the Time Delay parameter.

Generates a transition to low limit alarm if the value of the reference property is lower than the range of values determined by the Low Limit for a time greater than the number of seconds defined by the Time Delay parameter.
