Pepperl+Fuchs (www.pepperl-fuchs.com), one of the largest manufacturers of industrial sensors and sensor system for factory automation applications in the world, has announced the release of a high performance, versatile power supply built for larger process automation projects, the FieldConnex Compact Power Hub.
Unlike other comparable power supply offered in the market, the new FieldConnex Compact Power Hub consumes less cabinet space with its 150 mm x 268 mm footprint, as it provides eight segments of redundant power. The advanced passive impedance design and especially selected components allows the FieldConnex Compact Power Hub to deliver outstanding power and performance in less space without compromise. It also supports safe fieldbus segments according to High Power Trunk concept and the Entity Ex nL or Ex ic classification.
“The power supply modules that mount on the motherboard are just 12.5 mm,” said Brian Traczyk, Product Manager at Pepperl+Fuchs. “Depending on the module the typical power loss is only 1.3 or 1.6 watts, which promises a long service life with the most efficient control room cabinet-packing density available today.”
“And because the FieldConnex Compact Power Hub is designed with built-in redundancy, two power modules are assigned to each segment. This means that exchanging a failed power module does not require any interruption of the power supply, and will not affect plan operation.”
The compact motherboard of FieldConnex Compact Power Hub comes in various versions that suit numerous application needs. It also provides all necessary interfaces and wiring connections and can support up to 16 plug-in power modules, which are safely secured and plugged in without the need for other tools.

Pepperl+Fuchs (www.pepperl-fuchs.com) has announced the launch of its LS680 Series Optical Data Couplers, which allow live video communication with its unique capability of transmitting signals, a feature that was previously not possible in material handling applications. Compared to other competitive models in the market, the LS680 provides a cutting-edge speed, which is 33 up to 50 times faster.
In an effort to make the product a true tamper-proof, plug and play solution, the company has specially designed it without the need for programming and operating controls such as switches, buttons or potentiometers.
“Live video can be very helpful for maintenance, diagnostics, and feedback, especially for very remote or inaccessible locations, like high bays in a warehouse,” Product Manager Jeff Allison said. “In the past, users may have to shut down a line and send a technician to trouble-shoot if there is overhang from a bay. Now, these issues can be addressed remotely with live video from the trouble spot, which saves time and makes for a more secure system.”
Its optical data transmitter enables it to transmit various industrial Ethernet topologies such as PROFINET, Ethernet IP, and TCP/IP on the same product. It can transmit signals from a distance of 0 to 150 meters, providing a threshold distance of 180 meters. LS680 advanced features allow it to consistently transmit data at a rate of 100 MBit/s through a 100 Base-TX interface.
The LS680 optical data coupler serves as a “virtual cable” replacing the physical Ethernet cable, which has inherent electrical and mechanical limitations, such as susceptibility to noise, wear and tear and inflexibility.

Pepperl+Fuchs introduces the G10 family of Ultra-Compact I/O Modules with Connect & Done technology that can eliminate mounting requirements in many applications. The world’s smallest AS-Interface I/O module with IP68/69K protection, at just 40 mm x 27 mm x 22mm the G10 fits easily into any cable duct and enables quick, convenient sensor connections using the integrated M12 pigtails.
“With its tiny footprint, this exceptionally robust module allows mounting in the most space-confined applications. In fact, simply placing the G10 inside the cable tray may eliminate mounting entirely – that’s the power and simplicity of ‘connect and done’ functionality,” says Helge Hornis, Manager Intelligent Systems, Pepperl+Fuchs.
The robust single-piece housing makes use of a patented and field-proven hinged cover design that simplifies connectivity, ensures reliable contact to the AS-Interface flat cable, and typically eliminates any additional mounting requirements. For applications where mounting is required, two integrated M4 screw holes are provided. The G10 has no gaskets, inserts, separate housing parts, or additional screws that are easily lost.
“As with all other AS-Interface modules, Pepperl+Fuchs uses high-quality, machined, gold-plated piercing contacts that, unlike the cheap stamped and zinc-coated alternative, provide superior long-term contact stability without damaging the internal strands of the AS-Interface cable,” explains Hornis. “Placed around each of the piercing contacts is a concentric seal contour that provides high seal contact pressure, a main contributor to the reliable IP68/69K protection, even after many years of service.”
Sensors are powered from the yellow AS-Interface cable, and a continuous output current of up to 1 A can be supplied from AUX power. All versions of the G10 ultra-compact I/O module family are equipped with bright diagnostic and status LEDs that are visible from all directions. The G10 family also follows the latest AS-Interface specification 3.0.

October 26, 2010 by Motion Control Tips Editor
Filed under Fieldbusses, Networks, Software
Pepperl+Fuchs (www.pepperl-fuchs.com) has announced the release of its latest version of Advanced Diagnostic Module DTM software. The Advanced Diagnostic Modules or ADM check the quality of fieldbus communication for PROFIBUS PA networks and FOUNDATION fieldbus H1.
The Diagnostic Manager software offers a number of updates that speed up fieldbus commissioning and omit the guesswork of troubleshooting for ADM users. The software tool translates the data provided by ADM into actionable information. This diagnostic manager software has the capability to run on a server placed directly in the control room, turning the entire fieldbus infrastructure to an open book that can be read even with no expert knowledge.
“The most significant improvement to the new Diagnostic Manager is a built-in expert system that automatically learns the communications behavior of a segment during commissioning and over time, and is able to intelligently diagnose any situation based on past experience,” said Brian Traczyk, product manager of Pepperl+Fuchs.
“As a result users are provided with specific warnings as soon as the software detects any condition that might lead to a critical situation. Warnings are complemented by incident-related information in clear text that points to possible causes and recommends remedies.”
With this product, field technicians gain helpful information and will know what should be done before arriving on the site. They do not have to face the time-consuming task of looking for the cause of a problem. Thus, the time spent on troubleshooting is minimized, plant closure can be avoided, and the complete system’s availability is considerably improved.

New Pepperl+Fuchs Segment Checker design software for easy and quick validation of Profibus and Fieldbus PA Segments
April 15, 2010 by Motion Control Tips Editor
Filed under Fieldbusses, Networks, Software
Pepperl+Fuchs (www.pepperl-fuchs.us) is proud to announce the new Segment Checker version 1.20. The unique and easy-to-use Segment Checker is a tool use for validating the design of all Profibus PA and Foundation fieldbus segments, as well as hazardous areas. Machine builders can simply drag and drop components to the project window, and edit the attributes to make a fieldbus segment. The latest to this version 1.20 are the enhanced calculations for fieldbarriers and FieldConnex fieldbus products for fieldbarriers utilized in the High Power Trunk method. Moreover, Segment Checker 1.20 allows machine builders to export a product in a graphic format for different media.
The new Segment Checker version 1.20 features project-export functionality, new products, and enhanced calculations to further simplify fieldbus validation and design.
“Segment Checker automatically calculates the voltage drop and load current on a fieldbus segment for any given configuration. The user simply chooses the explosion protection method such as FISCO, Entity, FNICO and High Power Trunk, or the safe area, and segment design error checking makes clear whether the desired configuration is workable,” said Brian Traczyk, Product Manager of Pepperl+Fuchs.
The new Segment Checker allows machine builders to intuitively check their operational parameters to validate fieldbus PA segment architecture. Also, it allows machine builders to print, archive and display an entire design, and import the field devices from its library, or create additional devices by using the “device editor” feature. Moreover, machine builders can click on a device for straight access to the most recent product and technical information on the Pepperl+Fuchs website. Its cables can be tagged and attributes defined by the machine builder. The Spur cable’s length can be set to a defined number as well, removing the need of repetitive editing in larger projects.

Incremental Rotary Encoders from Pepperl+Fuchs
July 29, 2009 by Motion Control Tips Editor
Filed under Encoders, Encoders Rotary
TWINSBURG, OH – Pepperl+Fuchs introduces RVS58S Incremental Rotary Encoders with integrated safety technology. RVS58S encoders with self-diagnostics are specifically designed for use in safety aligned systems up to SIL3 in accordance with IEC 61508, performance level “e” in accordance with IEC 13849, and Category 4 in accordance with DIN EN 954-1. They are also suitable as a motor feedback system for safe drives in accordance with IEC 61800-5-2.
In response to these needs, Pepperl+Fuchs developed the RVS58S rotary encoder with functional safety that enables economical system integration. This new concept provides easier connection methods to the control system and allows it to be used in high safety category systems. Technically speaking, RVS58S incremental encoders have a sin/cos interface, 1024 or 2048 signal periods, and are thermally stabilized for high resolution interpolation. They operate at 5 VDC ±5% and deliver a maximum output frequency of 200 kHz in operating temperatures ranging from -20 °C …80 °C (253 K …353 K). They are rated to handle axial shaft loads of 40 N at maximum 6000 RPM or 10 N at maximum 12,000 RPM, and radial shaft loads of 60 N at maximum 6000 RPM or 20 N at maximum 12,000 RPM.
The industrial landscape is populated with ever faster high-performance machines, in whose environment a whole range of robots and automatic feed systems are also operating in order to ‘unload’ the operating personnel. In any application where such systems are in use and moving machinery parts are driven by high-performance systems, there is the potential for danger to the operating personnel. According to the Machine Directive and relevant safety regulations for health and safety in the workplace, even brief lapses in attention must not result in shearing, crushing and impact injuries – or worse. The preferred use of rotary encoders in such applications is to monitor rotating or swiveling components in drive systems, making them a core safety consideration in drives.
In order to keep the expense of safety measures within limits, rational safety concepts will increase in importance in the future. Consequently, in this context the functional safety of individual system components, such as rotary encoders, assumes new significance. This transpires against the background of a changing situation with regard to standards, since the standard EN 954-1, which has been binding since 1996, remains valid only up to 29.12.2009.
The deterministic approach of EN 954-1, of countering the deduced risk categories by means of an appropriate system behavior, will now be superseded by the more effective standards EN ISO 13849-1 and EN 62061. With their consideration of failure probabilities (probabilistic approach) these are also more in keeping with the requirements of modern programmable electronics, which has long been subject to the considerations of safety technology. The IEC 61508 serves as the higher-level standard for functional safety.
Since the architecture determines a significant proportion of safety costs, smart ideas can reduce these costs while even increasing the efficiency of sensor-system safety. The use of mechanisms featuring two-channel operation, without completely duplicated execution of the functional units, is an effective approach. However, even systems with two rotary encoders or a dual encoder do not necessarily have to be classified according to the new standard. In order for a sensor to receive a high safety evaluation, it must be ensured that the Safe Failure Fraction (SFF) and the degree of Diagnostic Coverage (DC) are appropriate to comply with the minimum requirements. Self-diagnosis implies that the device is able to detect its own fault conditions and then reliably communicate the same. In this way machines and control systems are able to immediately carry out a defined stoppage, before subsequent failures of any kind can lead to a dangerous situation.
