Used to edit, view, create, and delete variables.

FIELD DESCRIPTIONS

VarNum:The numeric variable identification.  Variable numbers don't need to be consecutive.  Variables are referenced by number when using many WIMS functions.  Typically, variables are displayed in Variable Number order. 

Location: The location (full path of location, i.e. WTP#1\Filters\F1) or sampling point of the variable. Click ... to browse for a location or type in a valid location to set the location for the variable.  Use Location Setup to add Locations to the list of valid locations. 

Name: The textual description of the variable (required).  This name can be up to 50 characters long. Use variables names that are descriptive of the process or meter producing the values.

Units Represents the units of measure associated with data entered for a variable (i.e. MGD for Influent Flow).  A combo box allows selection of units or simply type in units.  Click here to see how this list may be customized.  This field is not required.  The field length is limited to 20 characters.

Track Every: Sets how often data is to be tracked for the variable.  The following choices are available (Note when changing this value, you will be asked if you want to move data, see  Migrating data when changing a variable's Track Every Field article):

Track Every	Data Slots per day
Minute	1440
5 Minutes	288
15 Minutes	96
30 Minutes	48
Hour	24
4 Hours	6
Day	1

 

Type: Defines the variable as an input parameter, text parameter or a calculation.

Type	Description
Parameter	Numeric Entries (including variables that allow symbols (data qualifiers <,>, ND,...)
Text Parameter	Text or String Entries.  The List tab will be enabled allowing you to define a pull down list of entries.
Calculated	Value is calculated from the formula defined on the Equation tab.  The Equation tab is only enabled when the Variable type is set to Calculated.

Picture

The ability to insert pictures (ie. .jpg or .png)

Data Read-Only: Marks all data for this variable as Read-Only, i.e. it CANNOT be entered, edited, deleted in WIMS.  This is typically used when data is imported from another system such as SCADA or LIMS.  Note: Only Super users (or managers with the "Allowed to edit Variable's Data Read-Only Setting" User Setting) can uncheck this field.

Definition Read-Only: Marks this variable's setup as Read-Only, i.e. no fields on this form can be changed.  For example, our regulatory variables can be marked as Definition Read-Only which means no one can edit or delete the variable's definition without unchecking this field first.  Note: Only Super users (or managers with the "Allowed to edit Variable's Definition Read-Only Setting" User Setting) can uncheck this field.

Is Compliance: Flag that indicates that the parameter is compliance (regulatory) variable.
