SIWA – Digital Solutions For The Water Treatment And Management

In the market-specific solutions, SIWA focused on the digitalization of water and waste water plants. The solutions on display will cover the entire life cycle of plants – from planning through to operation and maintenance, helping to sustainably reduce energy consumption and lower the overall costs. Companies and municipalities are increasing both the efficiency and security of supply by, for example, planning, simulating and optimizing plants and processes using a digital twin. Innovations include new hardware concepts and industry-specific modules for the Simatic PCS 7 process control system, as well as automation over the TIA Portal using Simatic S7-1200 and S7-1500 and cloud-based solutions for the optimized use of pumps.

A digital twin of the real plant provides users with significant advantages over the entire life cycle of the plant. Siemens will be illustrating this with its main exhibit “From Integrated Engineering to Integrated Operations” demonstrating the integration of processes, operations and information across the plant’s entire life cycle: Comos engineering software, the latest version 9.0 of Simatic PCS 7, and the Simit simulation software. The latter enables virtual plant commissioning and operator training, enabling faster and error-free commissioning.

Comos innovations will be also showcased, such as pre-configured sample solutions for the water industry covering all engineering, electrotechnical and automation aspects and the integration of technological and geographical information into digital maps. A comprehensive device management (based on a modern IT infrastructure with “Comos as a Service”) will also be on display.

Tailored scalable automation solutions

Siemens offers pre-configured sample solutions (engineering templates) for Simatic PCS 7 and WinCC specifically for the water industry covering electrification, automation and drive systems. The templates include all functions required for control and regulation, including ergonomic visualization and operation. The scalable automation solutions can be adapted and adjusted to fit all needs: From TIA Portal for small and autonomous stations through to the WinCC SCADA system for distributed and heterogeneous water networks and complex plants using the Simatic PCS 7 process control system. This helps to significantly reduce the costs of plant engineering, operations and maintenance over the entire life cycle.

New data-based possibilities to optimize operations

Data networking can make processes more efficient and reduce costs in operations as well. Here, Siemens offers smart solutions: SIWA Leak and SIWA LeakControl help detect insidious leaks in water pipelines and networks. This solution supplements existing control systems and continuously supplies operators with information on the current status of the water pipes, providing them with a detailed data basis for making informed decisions on suitable action to be taken in the event of a leak. The SIWA Optim app, which will be also available as a MindSphere solution, will support staff in creating and optimizing pump and valve schedules for water supply networks helping to reduce energy consumption and costs by up to 15% whilst safeguarding the supply at the same time.

Transparency with SIWA comprehensive energy management

Siemens’ comprehensive energy management systems provide a holistic solution for the optimized utilization of resources which also help to identify potential savings in the overall operations. With Simatic Energy Management, Siemens provides an extensive ISO 50001 certified, scalable product and solution portfolio which helps to sustainably increase efficiency – from energy data capture at field level to business-wide energy analysis at management level.

Industrial security for critical infrastructures

Security plays a vital role in water supply systems as it constitutes a critical infrastructure. To protect industrial plants against cyber-attacks, Siemens offers its “Defense in Depth” concept. Industrial Security Services support early detection of potential vulnerability and threats. Together with the customer, Siemens then implements proactive measures of system hardening, anti-virus management, and network segmentation for long-term plant protection.

The Automation Firewall range serves to protect industrial plants by implementing special protective mechanisms for Simatic PCS 7 and Simatic WinCC. The Sinema Remote Connect management platform helps users to obtain convenient and secured remote access to widely distributed plants, stations or remote control centers. As early as in the design and development stages of products and systems, Siemens attaches utmost importance to IT security (including certification of compliance with, for example IEC 62443 and ISO 27001).

Industrial communication as a basis for digitalization solutions

SIWA will also be showcasing its extensive portfolio for industrial and robust communication. The compact and energy-saving remote control centers from the Simatic-RTU3000C range are used in, for example, applications without local power supply. With its comprehensive offering of modular remote control centers, substations can be adapted and scaled to meet the various requirements and integrated into heterogeneous automation environments.

New perspectives in field device connections – Plug-and-Produce

With its Simatic CFU (Compact Field Unit) field distributor installed closely to the process, Siemens has laid the foundation for digitalizing industrial plants in the water industry at the field level. Connected devices are automatically addressed. This novel implementation of Profibus and Profinet concepts combines the simplicity of point-to-point wiring with the scalability of digital field buses.

SIWA Process instrumentation

An industrial water model on display at the fair, which is entirely integrated into Simatic PCS 7, demonstrates a wide range of process instrumentation solutions and the seamless integration into the complete control system. Also on view will be such devices as the Sitrans FST020: With its Sitrans FSS200 clamp-on sensors, the powerful measuring transducer forms a digital flow metering system, measuring virtually any liquid with a consistently high accuracy of one per cent of the flow velocity. The battery-powered Sitrans F M MAG 8000 flow meter can be fitted almost anywhere without compromising accuracy or performance. The battery-powered device meets legal metrology requirements in accordance with water meter standards MID and OIML R49. It is specifically designed for autonomous water applications such as water intake, distribution, consumption billing and irrigation.

SIWA Services for higher efficiency in commissioning and maintenance

Service activities such as commissioning and maintaining field devices can be supported by modern communication media through remote access. In addition to maintaining the hardware platform, the life cycle costs of a process control system are determined to a significant degree by the maintenance and upkeep of the installed software components. Innovative concepts such as “Simatic Virtualization as a Service” help customers to reduce their capital expenditure on hardware considerably as well as spending on service and administration. Moreover, a central software and system administration makes for simpler implementation of security-related measures.
