Adapter integrates standard sensors in the IO-Link

09.11.2009
A new adapter from the Siemens Industry Automation Division makes it easy to integrate standard sensors into the IO-Link, the communication standard for the sensor/actuator level.

This means that the majority of sensor types available on the market can utilize the benefits of the IO-Link without any special modification, facilitating integration in the central diagnosis and detection of errors, for example.


The Simatic PX130C adapter features a number of signal conditioning functions and extensive diagnostics functions. It is especially suitable for drive solutions such as speed control and monitoring as well as rotational direction recognition, and for fast counters.

The Simatic PX130C adapter with high IP67 protection rating functions as an adapter plug for the connection of up to two binary proximity switches or a single analog sensor to the control level. For this purpose the adapter features two inputs which can be set to pnp or npn, one of which is digital, the other being either analog or digital. The analog input can be set to 0-20 mA, 4-20 mA or 0-10V. Most commonly-available sensor types can be connected to the adapter, which also applies to the more than 500 standard proximity switches of the Simatic PX portfolio from Siemens.

The Simatic PX130C adapter is equipped with a variety of functions. These include signal conditioning functions such as A/D conversion, rotational direction recognition, speed monitoring, input inversion, switching time measurement and timers with extended pulses, for example. The diagnostic functions monitor connected sensors for wire breaks, short-circuits and
overcurrent/undercurrent. Configuration takes place in the standard engineering tool using the supplied IODD (IO-Link Device Description). Settings can be made for signal conditioning functions, for example and it is also possible to parameterize averaging values or switch-on muting and determine whether the positive edge or the falling edge of a connected sensor should be detected.

The new adapter is especially advantageous when it is used in more sophisticated sensor applications. Typical areas of application include speed control and monitoring, standstill and slip monitoring or switchover and monitoring of start-up processes on drives. The wide range of functions means that the adapter can be used in all types of machines and plants, for example in wind power stations or CHP plants, belt conveyors and test stands or in large drives. In addition a combination of simple proximity switches enables detection of rotational direction in elevator systems, stirrers, pumps or fans, or the slip monitoring of belt and hydraulic drives.

The sensor adapter can detect both measure rapid counting processes up to five kilohertz as well as switching frequencies, thus also making it suitable for open and closed-loop control of agitators or oscillating conveyors. Since it is so versatile, the compact IO-Link Adapter PX130C makes additional speed monitors and counter modules in the control cabinet superfluous, and there is also no need for extra rotary encoders for speed detection and rotational direction recognition.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
