Siemens integrates Sitop power supply into Simatic PCS 7 process control system


Siemens at the Achema 2015, Hall 11, Booth C3

  • Integration of the Sitop UPS1600 uninterruptible DC power supply increases transparency about operating states and plant availability
  • Sitop library for Simatic PCS 7 as free download
  • More Sitop power supplies to be included in 2015

Siemens is integrating its Sitop UPS1600 DC UPS with Ethernet/Profinet interface into the Simatic PCS 7 process control system. The energy storage units of the uninterruptible DC power supplies with 24 V DC output voltage and 10, 20 or 40 amperes current facilitate buffering of power failures for up to several hours.

The Ethernet/Profinet interface enables users to integrate the UPS1600 directly into the control system. Information about the operating state can then be transmitted, evaluated and visualized via software blocks. The software also automatically creates alarm messages. Users are then in a position to detect impending failures early on and initiate countermeasures, thus increasing plant availability.

New Sitop UPS1600 software blocks in the Simatic S7 controller permit direct data transfer (of operating and diagnostic data, for example) into the message system as well as of UPS faceplates of the process control system. The maintenance information can then be evaluated and visualized by the maintenance system of the Simatic PCS 7.

In this way, users are clearly in the picture about the operating status of the power supply and connected energy storage units. During power outages or other disturbances, they can initiate counter measures or instigate replacement of the battery modules as measures to prevent potential downtimes. This is imperative particularly in the process industry since even short failures of individual components can result in high costs and in continuous processes can even make a time-consuming restart necessary.

In the coming months, Siemens will integrate more Sitop components, such as redundant 24 V network power supply units, or the Sitop PSU8600 power supply system, into the Simatic PCS 7 process control system. This provides optimum support during the engineering, operating and maintenance phases both for solution providers and plant operators using Sitop. The Sitop library for Simatic PCS 7 is available as a free download.

In a paper in Scientific Reports, a research team at Worcester Polytechnic Institute describes a novel light-activated phenomenon that could become the basis for applications as diverse as microscopic robotic grippers and more efficient solar cells.

A research team at Worcester Polytechnic Institute (WPI) has developed a revolutionary, light-activated semiconductor nanocomposite material that can be used...

Im Focus: Diamonds aren't forever: Sandia, Harvard team create first quantum computer bridge

By forcefully embedding two silicon atoms in a diamond matrix, Sandia researchers have demonstrated for the first time on a single chip all the components needed to create a quantum bridge to link quantum computers together.

"People have already built small quantum computers," says Sandia researcher Ryan Camacho. "Maybe the first useful one won't be a single giant quantum computer...

Im Focus: New Products - Highlights of COMPAMED 2016

COMPAMED has become the leading international marketplace for suppliers of medical manufacturing. The trade fair, which takes place every November and is co-located to MEDICA in Dusseldorf, has been steadily growing over the past years and shows that medical technology remains a rapidly growing market.

In 2016, the joint pavilion by the IVAM Microtechnology Network, the Product Market “High-tech for Medical Devices”, will be located in Hall 8a again and will...

Im Focus: Ultra-thin ferroelectric material for next-generation electronics

'Ferroelectric' materials can switch between different states of electrical polarization in response to an external electric field. This flexibility means they show promise for many applications, for example in electronic devices and computer memory. Current ferroelectric materials are highly valued for their thermal and chemical stability and rapid electro-mechanical responses, but creating a material that is scalable down to the tiny sizes needed for technologies like silicon-based semiconductors (Si-based CMOS) has proven challenging.

Now, Hiroshi Funakubo and co-workers at the Tokyo Institute of Technology, in collaboration with researchers across Japan, have conducted experiments to...
