Plant automation and telecontrol in the same system

20.03.2008
The latest process control system Simatic PCS 7 has now been expanded by the Siemens Industry Automation Division with telecontrol functions. Simatic PCS 7 TeleControl connects distant substations to the central control system by means of telecontrol.

In terms of the operating philosophy and alarm signaling, there is no difference between the local or distant station as far as the plant operator is concerned. Several different media are available for communication, such as dedicated lines, dial-up connections or radio systems.


The application range of the integrated, universally implementable telecontrol system extends from the oil and gas industry through to the water supply and treatment sector.

Simatic PCS 7 TeleControl integrates distributed, distant substations and a central control system to form a homogeneous overall solution. This allows applications to be created that are integrated with regard to operation and alarm signaling and the risk of operating errors as well as engineering and servicing costs are reduced. In large-scale plants, a redundant configuration increases plant availability and redundant servers compare their process values, curves and alarm statuses with each other.

Communication with the external substations is performed over dedicated lines, dial-up lines or radio systems and, in new plants, increasingly with TCP/IP-based techniques, with either DSL or GPRS. Simatic PCS 7 Telecontrol supports the Sinaut ST7 and Modbus protocols over serial as well as over TCP/IP-supported communication links. Further processing and archiving of the raw data complete with time stamps received from the distant substations are performed in the central PCS 7 TeleControl server. Simatic PCS 7 TeleControl function blocks are provided for this purpose for the Simatic PCS 7 standard control system. The user interface and error message hierarchy as well as the symbols and faceplates correspond to those of Simatic PCS 7 and present the user with the familiar system environment.

The Sinaut ST7 telecontrol protocol is designed to be robust and can also be implemented for slow or sensitive transmission paths. For example, data are buffered in the distant substations to bridge faults or sporadic connection interruptions in radio networks without losing important data.

The wide ranging applications of Simatic PCS 7 TeleControl extend from the oil and gas industry – for example, for compressors, pressure reduction, transfer and metering stations in gas supply networks as well as for pumps and valve stations in oil pipelines – through to the water supply and treatment sector. In the latter, the system provides telecontrol solutions for sprinkler, pump and valve stations in water supply networks as well as for rainwater overflow basins and hoisting plants in waste water systems.

Im Focus: Future electronic components to be printed like newspapers

A new manufacturing technique uses a process similar to newspaper printing to form smoother and more flexible metals for making ultrafast electronic devices.

The low-cost process, developed by Purdue University researchers, combines tools already used in industry for manufacturing metals on a large scale, but uses...

Im Focus: First evidence on the source of extragalactic particles

For the first time ever, scientists have determined the cosmic origin of highest-energy neutrinos. A research group led by IceCube scientist Elisa Resconi, spokesperson of the Collaborative Research Center SFB1258 at the Technical University of Munich (TUM), provides an important piece of evidence that the particles detected by the IceCube neutrino telescope at the South Pole originate from a galaxy four billion light-years away from Earth.

To rule out other origins with certainty, the team led by neutrino physicist Elisa Resconi from the Technical University of Munich and multi-wavelength...

Im Focus: Magnetic vortices: Two independent magnetic skyrmion phases discovered in a single material

For the first time a team of researchers have discovered two different phases of magnetic skyrmions in a single material. Physicists of the Technical Universities of Munich and Dresden and the University of Cologne can now better study and understand the properties of these magnetic structures, which are important for both basic research and applications.

Whirlpools are an everyday experience in a bath tub: When the water is drained a circular vortex is formed. Typically, such whirls are rather stable. Similar...

Im Focus: Breaking the bond: To take part or not?

Physicists working with Roland Wester at the University of Innsbruck have investigated if and how chemical reactions can be influenced by targeted vibrational excitation of the reactants. They were able to demonstrate that excitation with a laser beam does not affect the efficiency of a chemical exchange reaction and that the excited molecular group acts only as a spectator in the reaction.

A frequently used reaction in organic chemistry is nucleophilic substitution. It plays, for example, an important role in in the synthesis of new chemical...

Im Focus: New 2D Spectroscopy Methods

Optical spectroscopy allows investigating the energy structure and dynamic properties of complex quantum systems. Researchers from the University of Würzburg present two new approaches of coherent two-dimensional spectroscopy.

"Put an excitation into the system and observe how it evolves." According to physicist Professor Tobias Brixner, this is the credo of optical spectroscopy....
