InfoWater Pro recognizes three different types of Controls. They are as follows:

  • Initial Status - Initial status prescribes the initial setting for the InfoWater Pro Project element at the beginning of the Simulation, such as None, open, closed and setting. These controls on the element may be over written by either the Simple Controls or the Logic Control at any time during the Simulation duration. Click here for more information on Initial Status.

  • Simple Controls - A simple control allows the user to modify the status of elements (pipe, pump or valve) during a hydraulic simulation - depending on the state of some other element in the system as specified by the user.  For example, actual field operations may consist of having a pump turn on and off depending on the high and low water levels in a storage tank.  To model this type of situation, the user would place a simple control on the element in question.  Simple controls apply to both Steady as well as Extended Period Simulation (EPS) models. Click here for more information on Simple Controls.

  • Logic Controls (Complex Controls) - Rule Based Logic Controls are used by InfoWater Pro to perform a given action during a hydraulic simulation when a user specified condition is met.  However, unlike Simple Controls, rule based controls allow for the creation of multiple conditions to be satisfied before an action is performed.  Rule Based controls apply to only Extended Period Simulation (EPS) models. Click here for more information on Complex Controls. Logic Controls need to be turned On prior to running your model through the InfoWater Pro Model Explorer -> Operation tab -> Simulation Options dialog box by checking the Rule Control command. InfoWater Pro will read the Complex Controls only when this option is checked.

Note: Rule Based Controls over-write Simple Controls and Simple Controls will over-write Initial Status for the different data elements.
