Siemens is planning to acquire Process Systems Enterprise (PSE), a technology- leading global supplier of software and services for advanced process modelling. Advanced models are used within digital R&D, design and operations in the process industries to help make fast, safe and more efficient decisions through rapid and effective exploration of the decision space. PSE offers model-based solutions that span the entire process lifecycle via a unified and integrated set of tools. This provides a wide range of state-of-the-art model-based solutions that strongly complement the Siemens portfolio in the process industry sector and will also further strengthen Siemens’ position as a leading provider in comprehensive plant management over the entire lifecycle.
The technology is widely used in the chemicals, petrochemicals, pharmaceuticals and food and beverage industries to accelerate innovation, improve process design and operation, streamline R&D and manage technology risk. “The combination of high-fidelity predictive models and real-time process data play an increasingly important role in the digitalization of operations in the process industry. It is important to take the process knowledge that is already available in product and process development and to map it in predictive models, which can then be used to add value in the digitalization environment in every step of the lifecycle,” states Eckard Eberle, CEO of Business Unit Process Automation. “PSE helps us significantly here, because now we can integrate model-based technologies from PSE in our applications in the entire plant lifecycle. This makes us even better equipped to meet the specific requirements of our customers.” Costas Pantelides, Managing Director of PSE, says: “We are delighted to become part of the Siemens organization. Our technology and know-how are highly complementary to Siemens’ existing products, and our combined portfolio will build on Siemens’ already strong position in digitalization in the process industries, to deliver unprecedented benefits to our customers throughout the process and product lifecycle.”
The company has already been working with PSE successfully since June 2018 within a strategic partnership. As part of this initiative, new model-based solutions have been developed: for plant performance monitoring and forecasting, soft sensing, real-time optimization, nonlinear model-predictive control and operator training based on detailed process models. These solutions are based on the powerful combination of process models, which contain in-depth process knowledge, with real-time and historical process data. This provides the plant operator with efficiency and effectiveness gains by improve process control and maintenance planning, e.g. by predicting catalyst lifespans or coke build-up in furnaces.
The firm plans to purchase 100 percent of the share capital of PSE and to integrate its business into the Business Unit Process Automation, which is part of Siemens Digital Industries. The London-based company employs about 160 people worldwide. Closing of the transaction is planned for the fourth quarter of 2019. Both companies have agreed not to comment on the financial details of the transaction.

Bi-directional DC-DC converter series has extended voltage
TDK Corporation (TSE 6762) announces the introduction of the EZA2500W-32048 TDK-Lambda brand bi-directional DC-DC converter model to its EZA series. The extended high voltage range now covers 260 to 400Vdc and the lower voltage 36 to 65Vdc. The operating temperature has been increased to -10 to +50°C. Double sided protective board coating and long-life dust resistant fans have also been included.
Designed for energy storage systems with rechargeable batteries, this 2500W digitally controlled, compact 1U power supply can seamlessly change conversion direction from high voltage dc sources, powered by solar or wind, to 48Vdc batteries and vice versa. Other applications include lithium-ion battery testing as well as the use of regenerated energy from robots, cranes, autonomous ground vehicles and lifts. The EZA2500 can be used to replace large power resistors currently used for lift braking and use that previously dissipated energy to charge batteries. That stored energy can be used to either provide peak power for high torque demands or as battery back-up for power cuts.
The output voltage and current can be programmed and monitored using the RS-485 communications port. Multiple units can be operated in parallel by using the RS-485 interface to set units for “droop mode” current share. Alarm signals are also accessible, as well as remote on/off and under/over voltage functionality. The high voltage (grid) to low voltage (battery) isolation is 3,000Vac, grid to ground 2,000Vac and battery to ground 500Vac.
The dimensions for the EZA2500 are 43.6mm (1U) high, 423mm wide and 400mm deep. All models in the EZA series are certified to the IEC/EN/UL 60950-1 and IEC/EN/UL 62368-1 safety standards with CE marking for the Low Voltage, EMC and RoHS Directives. A five-year warranty is standard.

Industry 4.0 progress
In an ordinary year, PI (Profibus & Profinet International) would already – and once again – have presented its progress on Industry 4.0 work at the Hanover Fair – but this is no ordinary year. Nevertheless, the working group experts are working tirelessly on implementing concepts like the use of Profinet over TSN, fail-safe machine-to-machine communication and information models for vertical communication – virtually and at a safe distance, of course.
Obviously, this is not an easy time for an organization which has committed itself to the networking of automation systems, and especially also those of technical experts. PI has been part of the digital transformation from the very beginning, though, which makes it ideally equipped for this situation. This being the case, it is no wonder that the working groups chose to continue developing their concepts. Online meetings and processes have been part of everyday work at PI for many years, enabling effective and easy cooperation. To share this progress with Profinet users as well, PI is now implementing a number of different virtual methods of communication.
The focal point of this communication is the PI website, www.profibus.com/I40, where “Industry 4.0” is being rolled out again in its entirety. PI is focusing on the highlights of its Industry 4.0 work here, beginning with Profinet over TSN, OPC UA Safety and vertical communication. Additional concepts will be addressed and added successively over time. PI won’t just be providing an overview of the technology and leaving it at that – technical details on solutions and use cases for applications will be added as well. This gives device manufacturers and users solid information for their own implementation of Industry 4.0-compliant integration.
In addition to this digital content, PI will also be visualizing the Industry 4.0 workshop to enable discussion with users and enter into dialog in these trying times – times which everyone at PI hopes will be over soon. Regardless, the working groups will continue to work hard on implementing Industry 4.0, in keeping with the motto: Go digital. Go Profinet .
