SPM#_Thresholds
MASS FLOW
The SPM#_Thresholds are used to allow alerts to be sent when the values are beyond the threshold values that have been set for each parameter.
Mean Limit
Alert Limit value in percent change of the Mean compared with the baseline mean value.
High Variation
Alert Limit value in percent change of the Stdev compared with the baseline Stdev value.
Low Dynamics
Alert Limit value in percent change of the Stdev compared with the baseline Stdev value.
SPM_Active
SPM_Active parameter that starts the Statistical Process Monitoring when “Enabled”. “Disabled” turns the diagnostic monitoring off. Must be set to “Disabled” for configuration. Only set to “Enabled” after fully configuring the SPM.
SPM#_User Command
Select “Learn” after all the parameters have been configured to begin the Learning Phase. The monitoring phase will start after the learning process is complete. Select “Quit” to stop the SPM “Detect” may be selected to return to the monitoring phase.
Baseline Values
The Baseline Values are the calculated values from the process over the Learning Cycle.
SPM#_Baseline_Mean
SPM#_Baseline_Mean is the calculated average of the process variable over the Learning Cycle.
SPM#_Baseline_Standard_Deviation
SPM#_Baseline_Standard_Deviation is the square root of the variance of the process variable over the Learning Cycle.
The Mass Flow Function Block is a licensable block. It will be licensed on a new transmitter if the H01 option is ordered or it can be licensed in the field via a licensing code. Please contract your local sales person on how to acquire a license.
The Mass Flow Function Block has two distinct parts to its configuration. The first part is downloading the formula the block uses to calculate mass flow. The formula is generated by using the Engineering Assistant software. The two ways to download the formula is to have the factory do it on a new order which requires you to order and fill out a C2 Configuration Data Sheet or you can do it yourself by using a National Instruments Fieldbus interface.
The second part is configuring the Mass Flow Block to accept pressure and temperature inputs from other transmitters. The differential pressure is passed to the Mass Flow Block through a channel. The pressure and temperature inputs can be linked through any FOUNDATION fieldbus configurator.
