FMS Validation Rules

The CygNet measurement system contains several categories and types of validation rules. Rules are assigned to validation engines, where they comprise a set of checks against the data for a single associated Node. Each rule can be configured to automatically detect potential problems in your data, according to its configured limits and guidelines. The system processes normalized data for validation rules as it applies to the given data type. Data will be validated by device rules first, and then all other applicable rules will follow.

When configuring rule properties, you can name or rename the rule as desired. If you do not assign a rule name, it will retain the default rule name based on the rule type, as listed in the tables below. Multiple rules in a validation engine can have the same name, although you may want to assign unique names upon rule creation to more easily identify them. See Configuring Validation Rules for more information.

Validation Rule Categories

Validation rules are organized into the following categories, based on affected data types. For each category, available rule types are listed in the corresponding tables below.

Configuration Data
Gas Quality History
Periodic Metering History
Historical Data
Station
Gas Analysis Data
Job

See Managing Validation Engines for information about defining validation engines and their associated Nodes.

Specify the Severity, Data quality, a Minimum threshold value, the last # of records to consider, and Units to use See Notes below.

Notes:

The # of records value means the number of contiguous records prior to the one that currently arrived for validation. If a device supports hourly data, then one hour equals one record. If the PM History span is one hour, and you want to specify an average of one day worth of data, specify "24" and the system will calculate an average of the last 24 records prior to the existing one. This number cannot be "0": a value of zero (0) generates a validation exception for every history record in the date range.

The +/- value defines the absolute or percentage tolerance range. This number cannot be "0": a value of zero (0) generates a validation exception for every history record in the date range. The exception is DP: for Differential Pressure, null or zero (0) tolerance values will not trigger exceptions.

Source Consistency Check	Source Consistency	Gas Device	The system will validate that the source of the gas analysis sample is consistent with the source configured in the associated Node properties. Records failing validation will generate an exception.	Specify the Severity
Sum of Gas Composition validation rules: The system will validate the total of the gas composition data items, to determine if the value is within the specified tolerance from 100%; otherwise the value will be considered out of range and will trigger the exception process.
Sum of Gas Composition (Fraction)	Gas Comp Sum Frc	Gas Device	The system will validate that the gas composition total adds up to 100% within the specified tolerance. Records failing validation will generate an exception.	Specify the Severity, a +/- range for the tolerance, and Units to use (fraction)

Job Rules

The following table lists the available validation rule types for job records, and each rule's configuration options.

Rule Type	Default Rule Name	Valid Node Categories	Description	Configuration Options
Calibration Drift Threshold... validation rules: The system will validate the value of the selected job calibration item, over the specified set of contiguous calibration jobs, to determine if the set is within the high/low limit specified; otherwise (if the entire set exceeds the limit) the set of values is considered "out of range" and will trigger the exception process.
Calibration Drift Threshold - Diff Pressure High (Percentage)	Calib Drift DP High	Gas Device	The system will validate that the change in calibration data values is below the defined high drift threshold (by percentage) for the specified number of contiguous calibration jobs. Records failing validation will generate an exception.	Specify a High (percentage) drift tolerance, and the # of records to consider See Notes below.
Calibration Drift Threshold - Static Pressure High (Percentage)	Calib Drift SP High	Gas Device
Calibration Drift Threshold - Temperature High (Percentage)	Calib Drift T High	Gas Device
Calibration Drift Threshold - Diff Pressure Low (Percentage)	Calib Drift DP Low	Gas Device	The system will validate that the change in calibration data values is above the defined low drift threshold (by percentage) for the specified number of contiguous calibration jobs. Records failing validation will generate an exception.	Specify a Low (percentage) drift tolerance, and the # of records to consider See Notes below.
Calibration Drift Threshold - Static Pressure Low (Percentage)	Calib Drift SP Low	Gas Device
Calibration Drift Threshold - Temperature Low (Percentage)	Calib Drift T Low	Gas Device
Calibration Drift Range... validation rules: The system will validate the value of the selected job calibration item, over the specified set of contiguous calibration jobs, to determine if the set is within the drift range specified; otherwise (if the entire set is outside the range) the value will be considered "out of range" and will trigger the exception process.
Calibration Drift Range - Diff Pressure (Percentage)	Calib Range DP	Gas Device	The system will validate that the change in calibration data values is within the defined drift range (by percentage) for the specified number of contiguous calibration jobs. Records failing validation will generate an exception.	Specify a +/- range for the drift tolerance, and the # of records to consider See Notes below.
Calibration Drift Range - Static Pressure (Percentage)	Calib Range SP	Gas Device
Calibration Drift Range - Temperature (Percentage)	Calib Range T	Gas Device
Number of Calibration Points... validation rules: The system will validate the number of calibration points present for the selected job and data type, to determine if the number in the report matches the value specified; otherwise the value will trigger the exception process.
Number of Calibration Points - Diff Pressure (Absolute)	# Calib Points DP	Gas Device	The system will validate that the number of calibration points present in the job report matches the specified value. Records failing validation will generate an exception.	Specify the Number of points expected to be present
Number of Calibration Points - Static Pressure (Absolute)	# Calib Points SP	Gas Device
Number of Calibration Points - Temperature (Absolute)	# Calib Points Temp	Gas Device

Notes:

The High or Low drift threshold value defines the change tolerance by percentage. If this number is zero (0), the system detects drifts in value (either high or low, as applicable) and generates a validation exception when all (either high or low) records in the set are not of identical value.

The # of records value means the number of contiguous calibration jobs including the one that currently arrived for validation, therefore the value cannot be zero (0). In the event that a calibration test point value standard has been changed within the contiguous record range specified, the values will be ignored (no exceptions generated) until the specified number of calibration report records is generated within the span of the new point value standard.

The +/- value defines the tolerance range by percentage. If this number is zero (0), the system detects any drift in value and generates a validation exception when all records in the set are not of identical value.
