Model 300 – Balancing Waste
Model 300 Description
With Model 300 you can track how much product went in (Input Tag) to the Production Unit and then compare it to how much product came out (Output Tag). The difference is attributed to Waste. Conversion factors, (Input Conv Info and Output Conv Info) are used to convert the input units and the output units into common values. For example, if your input is measured in gallons and your output is measured in bottles, you can use the conversion factors to convert both to cases.
The functionality in this model is available only if you have purchased the Efficiency Module.
Model 300 Properties
The following Model properties are set up using the Plant Applications Administrator:
|
Property |
Description |
|
Maximum Run Time (Seconds) |
optional: Type the number of seconds you want the model to run. The default is 0 (zero), which means the model will not time out. Typically, you will want to limit the run time of the model only if troubleshooting the model (for example, one of the stored procedures is in an infinite loop). |
|
Model Processing Group |
Used for multithreading. See the Multithreading topic for more information. |
|
PT:InputTag |
Tag used to select the Historian tag used to retrieve the amount of product going into the Production Unit. |
|
PT:OutputTag |
Tag used to select the Historian tag used to retrieve the amount of product coming out of the Production Unit. |
|
Input Conv Info |
Factor used to convert value from the Input Tag into a common value. |
|
Output Conv Info |
Factor used to convert value from the Output Tag into a common value. |
|
TINT:Interval (Minutes) |
The value entered, in minutes, determines how often waste is calculated. For example, if you enter a value of 60, then every 60 minutes, starting at midnight, waste would be calculated. |
|
TOFF:Offset (Minutes) |
The value entered determines the number of minutes after midnight that waste is calculated. For example, if you set the offset at 5, then five minutes after midnight, the waste would be calculated. |
|
Deadband |
Determines the amount of waste that is considered "acceptable." |
|
Samp Type |
The Sampling Type determines how to acquire the Input and Output Tag Values. |
|
Lag Time (Minutes) |
Time delay to wait prior to trying to acquire values from the Historian. |
|
Def TypeId |
This is the default type you defined when configuring Waste. |
|
Def MeasId |
This is the default measurement you defined when configuring Waste. |
|
Reason #1 |
You can type one of the Reasons defined in the Reason Tree |
|
Reason #2 |
You can type one of the Reasons defined in the Reason Tree |
|
Reason #3 |
You can type one of the Reasons defined in the Reason Tree |
|
Reason #4 |
You can type one of the Reasons defined in the Reason Tree |
|
Max Rate Per Min (For Increase Samp Type) |
If the sampling type, Increase, is used, this is the maximum rate per minute allowed. Data above this rate is discarded. |
|
Reset Value (For Increase Samp Type) |
If the sampling type, Increase, is used, the Reset Value is the value that the counter resets at. |
