RMS Concepts
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
Parameter Type
Value and Units
Threshold Value and
Comparison Operator
Status Type
Reset Flag and Reset
Value
Minimum and Maximum
Values
Enumeration List
64
This is the name of the parameter. This name is displayed on the RMS server con-
sole 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.
This value indicates if this 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".
This is the current value of the parameter. Units are appended to the value when
displayed in the web console.
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 strings 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 value are supplied during registration but can be modified
by the administrator from the RMS server console.
The status represents the type of problem a faulted condition represents. Status
Types include "Help Request", "Maintenance Request", "Room Communication
Error", "Control System Error", "Network Error", "Security" and "Equipment Usage."
For example, when "Lamp Hours" changes from an un-faulted (not greater than
1000) to a faulted (greater than 1000), this change represents a "Maintenance
Request" status that requires an AV technician to repair the equipment. If the
"Device Online" parameter changes from "Online" to "Offline", this change could
represent a "Security" or "Control System Error" status.
These value are supplied during registration but can be modified by the
administrator from the RMS server console.
These values determine if and how the parameter can be reset from the RMS
server console. If the Reset Flag is set, then the administrator can reset the value
remotely. When the administrator selects "Reset" from the console, the Reset Value
is copied to the Value and the faulted condition is cleared. These values are useful
for parameters such as VCR "Run Time" which would be manually reset when the
VCR is cleaned.
These values are used to restrict the range of the threshold and reset values that
the administrator can enter on the RMS server console. These values would be
used when the parameter represents a value with a bounded range, such as a
Volume Level.
This value is used to restrict the range of the threshold and reset values that the
administrator can enter on the RMS server console. This value would be used
when the parameter represents a value with a bounded list, Power On and Power
Off.
