Abstract: A method is described for remotely configuring one or more remote terminal units (RTUs) of a supervisory control and data acquisition (SCADA) system. The method includes providing, using a graphical user interface (GUI), a configuration area in which to specify one or more configurations that define a custom object for one or more RTUs associated with a type of one or more industrial machines and identifying a subset of the one or more RTUs associated with the type of one or more industrial machines. The custom object defined by the one or more configurations is obtained and provided to the subset of the one or more RTUs associated with the type of one or more industrial machines, which are updated. Data from the type of one or more industrial machines is obtained using the custom object and thereafter converted, via the subset of one or more RTUs, from the type of one or more industrial machines to another type.

Abstract: An embodiment provides for error analysis and remediation of one or more remote terminal units (RTUs) of a supervisory control and data acquisition (SCADA) system. In one example, a method determines an error associated with an RTU and generates one or more error messages. An error code of the one or more error message is extracted to identify an error type and the error type is associated with analytics data indicative of the error. In some examples, the error is an update error that can be analyzed to trigger a remediation workflow, for example to attempt to retry an update workflow with modified configurations.

Abstract: A method is described for controlling one or more industrial machines based on external contextual data and monitoring data of a supervisory control and data acquisition (SCADA) system. The method includes obtaining, using an application programming interface (API), the external contextual data from one or more external sources. Monitoring data including one or more alarms obtained from one or more remote terminal units (RTUs) associated with the one or more industrial machines is identified. The external contextual data is integrated with the monitoring data to form a combined display of the external contextual data and the monitoring data. Data is provided that visually associates the external contextual data and the one or more alarms in the combined display. Thereafter, a control instruction is communicated to the one or more industrial machines, via the one or more RTUs. The control instruction is configured to change the state of the one or more industrial machines to address the one or more alarms.

Abstract: Methods and systems are disclosed for meeting a fresh air ventilation threshold in a controlled space. In particular, and in some embodiments, a minimum ventilation threshold is met by using normal air handler fan cycles to minimize the energy cost of supplying the ventilation. Prediction methods may be employed to determine whether the air handler and damper need to be activated to meet a minimum ventilation threshold, even when the HVAC system is not currently calling for normal air handler fan cycles. In some cases, the past history of air handler fan run cycles is used to determine whether a fan should be operated now to provide additional fresh air ventilation. Alternatively, or in addition, predictions of future air handler cycles are used to determine whether a fan should be operated now to provide additional fresh air ventilation.

Abstract: A gas valve body with a first flow chamber and, a second flow chamber including and a main valve positioned in line and between the first flow chamber and the second flow chamber. The main valve can be opened by creating a pressure differential across the main valve. An electrostatically controlled pilot valve is provided for controlling the pressure differential across the main valve for “on-ff” operation. The electrostatically controlled pilot valve may also be operated to “modulate” the pressure differential across the main valve along a range of pressure differential values.
