Systems and methods include a computer-implemented method for displaying future trends of evaporation pond wastewater quantity and quality. A distributed float network is managed using a wastewater evaporation pond management (WEPM) system with an embedded supervisory control and data acquisition (SCADA) system. The WEPM collects data, including sensory information, from evaporation ponds. A configuration data upload for remote terminal units (RTUs) managed by the WEPM is automated using the WEPM system and the embedded SCADA system. Evaporation pond wastewater quantity and quality and adherence to environmental standards and regulations are monitored using the WEPM system. Environmental compliance data is collected from the distributed float network. The environmental compliance data collected from the distributed float network managed by the WEPM system is analyzed. A dashboard is provided displaying future trends of the evaporation ponds wastewater quantity and quality.

A method of controlling a real production process, wherein the method includes: a) receiving initial condition data from an on-line simulator system simulating the real production process, and b) performing an optimization based on the initial condition data and on an objective function to obtain set points for controlling the real production process.

A SCADA web HMI system generates an integrated component by grouping components including a first component and provides a first animation effect to the integrated component. The first animation effect is applied to the integrated component as a whole but not individually applied to components constituting the integrated component. The system provides a second animation effect to the first component. The second animation effect is applied to the first component but not applied to the components constituting the integrated component except for the first component. The system associates the first animation effect with the value of a first PLC signal and changes the appearance of the integrated component according to the value of the first PLC signal. The system associates the second animation effect with the value of a second PLC signal and changes the appearance of the first component according to the value of the second PLC signal.

Systems, devices, and methods include protective functions in an electrical power system. For example, a processing subsystem may include a first processor and a second processor. The first processor and the second processor may operate independently. A memory subsystem may comprise a first memory section and a second memory section. A memory management subsystem may enable memory access between the first processor and the first memory section and disable memory access between the first processor and the second memory section. The memory management subsystem may further enable memory access between the second processor and the second memory section and disable memory access between the second processor and the first memory section. A protection subsystem may include the first processor and the first memory section and enable a protection function. The second processor and the second memory section may provide a second function that operates independently of the protection function.
