Parameter Values

Each parameter has a set of values used to determine what conditions indicate a

problem and what type of problem this condition represents. These values are

supplied when the parameter is registered and consist of the following:

Parameter Values

Name This is the name of parameter. This name is displayed on

the RMS application console and readily identifies the

parameter. Parameters are tracked by name so this name

must be unique within the parameters of a given device.

For instance, you can have multiple "Lamp Hours"

parameters as long as there is only one "Lamp Hours"

parameter per monitored device.

Parameter Type This indicates if the value is a number or a string. This

information is used to determine how to perform

certain operation, such as addition and comparisons

between the new and threshold values. For instance,

comparing "10" and "2" as strings results in "10" less than

"2" but comparing them as numbers results in "2" less than

"10".

Value and Units This is the current value of the parameter. Units are

appended to the value when displayed in the web console.

Threshold Value and

Comparison Operator

The threshold value is the value for which this parameter is

considered to indicate a problem or fault. The comparison

operator is used to detect when the value changes from

the un-faulted to the faulted condition. The comparison

operators "Less Than", "Less Than or Equal To", "Greater

Than", "Greater Than or Equal To", "Equal To", and "Not

Equal To" can be used for string and number parameters.

The comparison operators "Contains" and "Does Not

Contain" are primarily used for string parameters.

For example, "Lamp Hours" might have a threshold value

of 1000 and any value over this would require

maintenance. The comparison operator would then be

"Greater Than". When this parameter changes from a

value that is not greater than 1000 to a value that is

greater than 1000, the fault status is set. When the value

changes from a value greater than 1000 to a value not

greater than 1000, the fault status is cleared. These values

are supplied during registration, but can be modified by the

administrator from the RMS application console.
