Compact distributed I/O for plant and machinery construction

The Siemens Industry Automation Division has expanded its Simatic ET 200 distributed I/O product family with a new generation of devices.

The especially compact design of the Simatic ET 200SP reduces the space required in the control cabinet and the device is characterized by user-friendly operation. Users in plant engineering and machine manufacturing benefit from the variable station set-up, fixed wiring and improved device and module identification features. The Simatic ET 200SP with IP20 degree of protection supports Profinet, is characterized by a fast cycle time and high system performance and can be integrated into the automation solution via the TIA Portal or Simatic Step 7 engineering tools.

Simatic ET 200SP

The new Simatic ET 200SP distributed I/O is based on a scalable design with variable station set-up options. The basic device can be expanded with up to 64 modules and can thus process 64x16 signals in the maximum configuration which still only requires one meter in the control cabinet. The compact design also means the system is suitable for standard control boxes with a depth of just 80 mm, even observing the standard bending radii. The integrated power module also saves additional space and simplifies load group formation.

During system design, great importance was attached to simple handling and practical use. The low parts variance also reduces warehousing costs for the user. No tools are required for installation and the user also saves time by simply combining the station modules. Mechanical coding protects the modules from damage if they are wrongly inserted, and a lateral latch mechanism provides a high degree of connection stability, even for vertical installation. In addition, it is possible to replace modules and terminal boxes during operation without risking station failure. Wiring has been simplified by the improved arrangement of the slots on the terminal box (rotated through 90 degrees) and the easy push-in technology. Module markings clearly display the most important wiring and channel information. Color-coded labels also simplify assignment of cables to the terminal box. The user can also identify machine and plant-specific modules with the help of identification plates and labeling strips.

The Simatic ET 200SP is equipped with two Profinet interfaces and an internal data rate of 100 Mbit/s ensures delivery of a high system performance. The backplane bus is isochronous with Profinet and can thus provide high-precision, virtually jitter-free data transmission. The bus adapter allows the user to freely select the most appropriate Profinet connection technology: RJ45 or FastConnect. The integrated shield concept, from cables to shield connection elements for the terminal box, to backplane bus and Profinet cable provides the system with a high degree of electromagnetic compatibility. Simatic ET 200SP is equipped with Profienergy functionality facilitating the coordinated deactivation of individual loads or entire production units during unproductive periods.

Im Focus: Etching Microstructures with Lasers

Ultrafast lasers have introduced new possibilities in engraving ultrafine structures, and scientists are now also investigating how to use them to etch microstructures into thin glass. There are possible applications in analytics (lab on a chip) and especially in electronics and the consumer sector, where great interest has been shown.

This new method was born of a surprising phenomenon: irradiating glass in a particular way with an ultrafast laser has the effect of making the glass up to a...
