Safe shutdown of motors up to SIL 3/PL e in process automation

24.02.2011
Two new fail-safe digital modules from the Siemens Industry Automation Division are implemented with the motor management system Simocode pro for safe shutdown of motors in process automation.

The modules DM-F Profisafe and DM-F Local fulfill the requirements of the IEC 61508/62061 and ISO 13849-1 standards for functional safety up to SIL 3/PL e. DM-F Local safely shuts down the motor in response to a local fail-safe signal from a sensor or controller, DM-F Profisafe receives the fail-safe signal via Profibus from a fail-safe controller. Simocode and the two new modules are configured using the Simocode ES software. For fail-safe applications with DM-F Profisafe, ready-to-use library blocks certified by the German Technical Inspectorate (TÜV) are available in the Step 7 option packages Distributed Safety and S7 F-Systems.


Simocode pro is a flexible and modular motor management system for motors in the low-voltage performance range. The system can be connected to higher-level automation systems via Profibus and covers the functions between the motor feeder and the automation system. Simocode pro combines all the necessary protection, monitoring and control functions for each motor feeder in a compact system. The motor management system offers complete, multi-functional electronic protection; safe shutdown of motors; integrated control functions; as well as detailed operation, service and diagnostics data. These functions are also provided autonomously by the automation system.

Im Focus: Temperature-controlled fiber-optic light source with liquid core

In a recent publication in the renowned journal Optica, scientists of Leibniz-Institute of Photonic Technology (Leibniz IPHT) in Jena showed that they can accurately control the optical properties of liquid-core fiber lasers and therefore their spectral band width by temperature and pressure tuning.

Already last year, the researchers provided experimental proof of a new dynamic of hybrid solitons– temporally and spectrally stationary light waves resulting...

Im Focus: AchemAsia 2019 will take place in Shanghai

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

Im Focus: Sharp images with flexible fibers

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
