UHF Know-How Purchased ”
It is true that Turck has had an established presence in industrial automation. For both partners, this collaboration is a milestone in the development of the companies, from which the customers directly benefit. Turck has obtained full unrestricted access to the development, know-how and proprietary rights to the deister UHF technology and may use it at its own discretion within automation technology.
This means that in Turck the customer has a partner for RFID projects that not only offers extensive application and solution knowledge in the HF and UHF range, but also a total package of top quality products for any sector in the market. We will show our developments in the UHF range in the autumn at the SPS/IPC/Drives fair. Turck has obtained full unrestricted access to the developments, the know-how and the property rights of the deister UHF technology, and can use it at its own discretion in the field of automation technology.
It transmits the individual measuring signal from a measuring instrument in the field directly to the PLC.
A Seamless Package
This requirement is not possible for many installations as the topology is more complex compared to a remote I/O solution.
Complete physical layer portfolio
Free choice of installation location
This makes it possible to check the entire cabling of the fieldbus, and also to diagnose and configure the HART field devices with their associated DTMs. In this way, a validated transfer from the field installation to the control system is possible.

Independent startup with DTM
The company builds briquette presses and shredders and has often benefited from this type of new legislation. Only then are the right temperatures produced to fully burn any toxins from glue and paint. Today, everything that is recycled – whether it is aluminum or other metals, plastics, insulation materials, carpet waste or waste paper – is pressed into briquettes to optimize the storage, treatment and transport of properly sorted waste.
However, the main customer of briquetting presses is the wood industry, which uses them to meet the increasing demand for combustible fuel for fires or furnaces. With its crushers and briquette presses, Weima is one of the market leaders in Europe. In both product groups, the company now uses Turck's LI-Q25 inductive linear position sensor.
Wear-free position sensors are now in operation in two shredders and in the briquette press TH 1500 M as well as the larger model TH 3400 M.
Position sensing the double press form
Wood waste must be chopped and burned with an oxygen mixture. Compared to bulk wood chips, a wood briquette reduces the space required by 90 percent. This enables an ISO standard container to transport 30 tons instead of seven when filled with wood briquettes instead of chips.
Precise Presses
For this, the PLC moves to the "Left position" and "Right position" of the press mold and records the relevant measured values of the linear position sensor as switching points. The PLC evaluates the 4...20 mA analog signal only in relation to the two positions of the dual form and for visualization.
Position sensing of the press stamp
Linear position sensor instead of bead chain
In this application, the linear inductive position sensor can fully exploit its strengths, since in this case not only contact information is required, but also precise position information. The setting is carried out in the same way as the other two cases by means of a learning routine of the PLC. However, Steiner also appreciates the possibility of visualizing the entire press operation on the display: "Visualization is very important to us.
The user can now follow and set the entire press operation one by one on the visualization screen. If the machine ever stops at a position that is difficult to reach, all parameters can now be set from the control box – something that was not possible before.”
Competitive edge of the Turck linear position sensor
Especially in difficult times, the number of visitors to the amusement parks has increased significantly - and continues to do so," explains Wolfgang Brück, director.
Flying Fish
The company was founded in 1930 in Deggendorf in Lower Bavaria and is one of the leading providers of family amusement parks. As a result, Disneyland, Universal Orlando, Tivoli Copenhagen, Busch Entertainment Corporation, Movie Park, Everland Korea and many other theme parks around the world are the company's clients. Zierer Karussell- und Spezialmaschinenbau GmbH has previously measured the horizontal position of the nacelle arms using individual proximity switches in its Flying Fish circuit.
However, with five sensors for each of the twelve hydraulic cylinders, assembly, calibration and integration into the travel control system were really complicated, especially since the height measurement could only be approximated. To determine the horizontal position of the arms, Zierer previously used five sensors on each hydraulic lift cylinder. Although this ensured safe operation, installing the sensors and adjusting them was relatively complex.
But there was another reason why the designers were looking for an alternative detection method: the position of the nacelles could not be accurately determined at any time, but only at five critical points where the sensors were placed.
Alternative linear position sensor
Otherwise, the gondolas could jerk to the final stop, which would not be a pleasant experience for the riders.
Fun with optimum safety ensured
With its short blind zones, IP67 and non-contact inductive positioning element, the LI sensor is ideal for the tough use required in fairground machines. Zierer electrical engineering specialist Matthias Niedermeier parameters the LI sensor appropriately via the IO-Link interface, which also supplies all error signals to the PLC. In addition to testing sensors from other manufacturers, the Zierer project team also tested the LI-Q25 inductive linear position sensor from Turck.
Magnetic or metallic environments, offset or vibration cannot impair the accurate measurement function of these linear position sensors. The LI-Q25 has very short blind spots because the sensing electronics are integrated along the entire length of the sensor. Even with fast movements and the resulting centrifugal forces, the sensor reliably provides the exact position of the positioning element via the 4...20 mA analog signal.
Based on this, the control can determine the exact position of the arm at any time.
Parameterization via IO-Link
This sensor works according to the resonant circuit measuring principle, which offers a high degree of precision and interference immunity. Unlike magnetostrictive sensors, position detection is not realized via a magnetic positioning element, but with an inductive resonant circuit, i.e. Project manager Klaus Gäck was completely satisfied with the test result and summarized it as follows: “For us, the quality and reliability of all components in the operation is very important.

Conclusion
Plug and play
To ensure this and eliminate errors as much as possible, a car manufacturer in China uses RFID in its engine production to assemble moving parts.
On the Right Track
Multi-variant production
The tags are placed on each individual shelf frame and move past the read/write heads of the stations. This allows assembly line workers to manually perform read/write operations to spontaneously check tags without having to initiate a stop on the assembly line. As different fieldbus protocols are used in the application for different tasks, the modularity of Turck's BL ident RFID system made a good impression.
System integrator Tianyong Mechatronics chose Turck's BL ident RFID system – because the modular system could be easily integrated into the existing Profibus DP and Modbus TCP network structure. Turck's BL67 I/O system provides communication with the PLC via Modbus TCP and Profibus DP The RFID read/write head reads the tag on the. A port communicates via Profibus DP with the Mitsubishi PLC and is responsible for the control and communication of the RFID read/write heads.
The UHF read/write heads can be connected to the same BL67 I/O stations if the system requires the integration of additional identification tasks using the larger UHF sensor range in the future.
Impressive modular solution
Light signals at the corresponding shelf spaces indicate to the worker which parts must be selected for each specific engine. A worker brings the carts with several vertically stacked boxes to the assembly line, where they are transported by a conveyor belt on multi-layer carts. The system can thus assign the right engine to the picking containers and enable the production of several engine variants on a single assembly line.
This enables the current production status of each engine to be called up at any time. The system also writes test values on the labels and measures data taken at the production stations, comparing them with the reference values stored in the database. The labels also contain the IDs of the engine and the components as well as additional information.
This provides the automaker with complete statistical data on production, allowing error accumulations and their sources to be systematically identified and rectified.
Interface Technology 2.0
Minimum engineering expenditure
The pin assignment of the system connections is adapted directly to the relevant process control system, so that users no longer need special connection modules, and instead can use cheap prefabricated 1:1 cables that are readily available – a significant advantage in terms of providing the electronic components used as well as the installation and maintenance costs of the interface level.
