SCADA Element Updates

Several updates to the SCADA Element used with SCADAConnect Simulator in WaterGEMS are included in this release.

Difference and Difference (Relative) result field

These fields display the difference between the calculated value for the SCADA Element and the model element. The Difference field is the absolute value, while the Difference (Relative) is displayed as a percentage.

Tank Status

The tank status, i.e., if the tank is filling or emptying, is now available as a Field for the SCADA Element. If the user has SCADA data related to the status, the user will now be able to compare the status in their SCADA data to the results in WaterGEMS.


SCADA Elements can now to used in the Alerts, allowing the user to create custom notifications related to the given results, including Model Result Value, Historical Signal Value, Difference, and Difference (Relative). So if you wanted to see an alert if the relative difference between the model result and the SCADA value was above a certain value, you can set this up.

SCADAConnect Simulator Updates

In addition to the updates to the SCADA Element, improvements and updates to SCADAConnect Simulator in WaterGEMS are also included, which will enhance and improve the usage of SCADAConnect Simulator. 

Automatically Import Control Overrides 

This will allow the user to automatically import control overrides when using the Historical or Historical (Live Training) simulation modes. If there are control overrides that are outside of the Difference Tolerance value, the control overrides will be automatically imported. The user can opt to set this automation field to False and manually update the control overrides.

Outage visualization when modeling Pipe Breaks

The user can now display the outage segments on the drawing when modeling a pipe break. This will be useful for an operator wants to see the pipe segments that will be offline when a pipe break is isolated.

An outage polygon can also be displayed, giving the operator a good visual representation of the impact of an outage.

More information on SCADAConnect Simulator can be found here: Using SCADAConnect Simulator.

Pump Status FlexTable and graphing Pump Status

A new Pump Status FlexTable has been included with this release. This will show results at a given time step for the pumps in a model, as well as sparkline that will display how the status changes with time.

In addition, you can now graph the pump status directly from the Graph manager.

Stability enhancements and fixes to reported issues

As with all new versions, this release of WaterGEMS and WaterCAD includes fixes to various user-reported issues from the previous release, providing an overall more stable experience.
