Control Performance Analytics - CPA

As the complexity of industrial process applications grows, so do production management requirements for process safety, adaptability, and product quality. More openness is required to recognize the possibility for process improvement and fine-tuning.

Control performance is critical in process industries for meeting production objectives. Each process application begins with a single control loop. According to studies, around 50% of all control loops are not well-tuned, whether owing to non-optimal settings, manual operation, oscillating controlled systems, or mechanical faults with control valves.

Furthermore, process engineers are generally in charge of hundreds of control loops in large-scale process facilities. Evaluating control performance across several process stages for alarms takes a significant amount of effort and knowledge. Due to continuous process changes and equipment wear and tear, detecting potential areas for improvement and modifying control loops is not a one-time activity.

Automated Control Loop Analysis for Efficient Plant Optimization

CPA is a cloud-based managed service that improves the transparency of process data and the optimization of control loops. The collection and analysis of plant-wide data provide the client with comprehensive product control. Automatic KPI (key performance indicators) computation identifies control loop states, which can recognize setpoint tracking, steady-state difficulties, and even static or sliding friction in-process valves. The tool also enables automated testing of new parameter sets to test control loops without interfering with plant operations.

CPA - What Is It?

CPA takes data from SIMATIC PCS 7 or any other process control system, for example, in CSV format, and sends it to Siemens' cloud-based IoT operating system, such as MindSphere, through a secure connection. CPA creates reports and recommendations for the customer's support teams or Siemens' process consulting specialists to analyze based on the data. Finally, optimization ideas help to enhance the process.

Benefits of Control Loop Optimization Through CPA

  • Increased product quality due to lower fluctuation in process variables
  • Maximized equipment lifetime due to reduced variability in actors
  • Improved set points raise throughput by going closer to the limits
  • Resource savings thanks to improved set point tracking behavior (e.g., energy, raw material)
  • Reduced manual mode of control loops allows overlaying control optimizations such as Advanced Process Control
  • Fewer alarms and fewer operator interactions reduce operators‘ workload

Compact Portable Samplers: The Foundation for Your COVID-19 Wastewater Surveillance Program

COVID-19 Wastewater Surveillance

An effective COVID wastewater monitoring program relies on representative samples. 

Water samplers are critical components in developing and deploying a community-based underground sewage surveillance program for COVID-19 outbreak detection, including best practices for wastewater sampling, lab analysis, and the immediate delivery of actionable information to local public health officials and administrators.

Wastewater testing refers to numerous water quality procedures examining wastewater's physical, chemical, and biological qualities. 

Officials in certain areas are analyzing wastewater to see whether it contains Covid-19. The test looks for ribonucleic acid (RNA), Covid-19's genetic material, in feces found in sewage and wastewater. 

SARS-CoV-2 causes Covid-19. According to studies, people with SARS-CoV-2 start spilling the virus in their feces shortly after infection. The virus's DNA enters the huge wastewater collecting network. The viral content of a community's wastewater may reflect the prevalence of Covid-19. Modern sampling and analysis methods can identify and quantify it up to a week before people test positive in clinics. Individual testing, contract tracking, and quarantine are possible mitigation and reaction methods. It also enables population sampling and monitoring of large-scale public health initiatives. 

Analysis of viral concentrations in particular institutions such as nursing homes and college dormitories and neighborhoods or whole communities may help restrict the spread and avert additional harm. 

The CDC created the NWSS in September 2020 in response to the COVID-19 pandemic. The CDC's National Watershed Surveillance System (NWSS) coordinates and increases the nation's ability to monitor SARS-CoV-2. 

There may be a way to identify the new Coronavirus in low quantities in wastewater. Many states, including Colorado, Ohio, New York, and Wyoming, have successful Covid-19 wastewater testing programs. Universities and municipalities use this method to identify community hotspots. Multiple success stories have proven early identification and control using dorm wastewater monitoring and individual COVID testing. These universities were among the first to use COVID patterns in wastewater to reduce community spread inside dormitories and across campus. 

Representative samples facilitate COVID wastewater monitoring. For COVID-19 epidemic identification, water samplers are essential for wastewater collection, lab analysis, and quick distribution of actionable information to local public health authorities and administrators. These data disclose the population numbers in a specific geographic region to estimate the virus's prevalence and quantity in wastewater. Combine Hach® small portable samplers with laboratory testing for automated composite wastewater sample collection that may help avoid outbreaks.
