Chinese Wind Farm Gains Reliability with Redundant Fiber Backbone

Project Introduction

Dongfang Steam Turbine Works (DSTW), a Chinese manufacturer of steam turbines, was working on a wind farm project involving 66 1.5 MV wind turbines in Heilongjiang, China. DSTW needed to establish a SCADA system that helps the staff remotely monitor on-site equipment and operations while recording data about ongoing operations for real-time analysis. Due to the harsh weather conditions in Northeast China, the networking devices must be extremely rugged to operate reliably. DSTW found that Moxa’s IKS-6726 rackmount managed industrial Ethernet switches and EDS-408A industrial Ethernet switches were a perfect fit for their specific network infrastructure requirements.

[caption id="attachment_290" align="aligncenter" width="450" caption="MOXA Industrial ethernet switches for WIND power"]MOXA, Wind, Power[/caption]

System Requirements
• Wide operating temperature to adapt to harsh weather in Northeast China
• Network redundancy with fast recovery capability for system reliability
• At least three fiber optic ports for uplink and long distance outbound transmissions
• Network management software for easy system monitoring


Moxa's Solution
One EDS-208A-M-SC industrial Ethernet switch is installed atop each wind turbine to connect to the equipment inside the turbine. This switch at the top connects to an EDS-408A-2S1M-ST-T switch at the bottom of the turbine via a fiber optic port.
The EDS-408A-2S1M-ST-T switch comes with three fiber optic ports; one fiber port is the uplink connection to the EDS-208A-M-SC and the other two connect to adjacent wind turbines.
Due to extremely high security and availability requirements, DSTW deployed a ring topology in the wind farm network to provide fast redundancy in case of network failure. The control center employs IKS-6726 rackmount managed industrial Ethernet switches to connect field switches with the SCADA system and network management servers. Moxa’s MXview network management software was also installed to help operators easily monitor network status by automatically discovering the network topology and displaying real-time alarm information.


Why Moxa?
• The EDS-408A provides three fiber optic ports for long distance data transmission with an ST connector ideal for vibration-heavy wind farms.
• The wide -40 to 75°C temperature range of theEDS-208A-M-SC, EDS-408A-2S1M-ST-T, and IKS-6726 allows for reliable operations under extreme temperature conditions
• The EDS-408A-2S1M-ST-T and the IKS-6726 support redundant Turbo Ring topology with recovery time less than 20 ms to increase system reliability and network availability
MXview network management software is capable of discovering topology automatically

Wireless system InduraNET p now with IP67 wireless module by Pilz

A remote IP67 module is now available for the wireless system InduraNET p (Industrial Radio Network) from Pilz. The remote module for the wireless system has been specially developed for use under difficult industrial conditions and can withstand water, dirt and heavy vibration. As a result, reliable wireless data transmission is now available on mobile plant and machine sections.

[caption id="attachment_276" align="alignleft" width="188" caption="Pilz PSSuniversal wireless modules"]PSSuniversal wireless modules[/caption]

Thanks to its special shake-proof, vibration-proof design, the remote module can be installed directly on mobile machine parts, enabling efficient wireless communication, even under a heavy industrial load. As a result it can also be used outside the control cabinet, saving space inside the control cabinet.

Four special, compact antennas enable efficient wireless communication despite strong reflections and constantly changing conditions for spreading the radio waves. The result is a stable wireless connection that guarantees high availability and reduces downtimes.

InduraNET p uses the "Listen before Talk" mechanism to detect other wireless systems - such as WLAN - and does not affect them adversely.

The industrial wireless system InduraNET p consists of a base station and a remote station; communication is possible in both directions. A base station can communicate with up to four remote stations; a maximum of ten InduraNET p networks can co-operate within one environment without problem.

InduraNET p is used in conjunction with the decentralised I/O system PSSuniversal, which can be used to process all common control signals decentrally at field level. PSSuniversal can be connected to all familiar standard bus systems as well as SafetyBUS p.

“Care Free” Development Package for Vendors Implementing Safety over EtherCAT

Safety over EtherCAT Technology enjoys strong, growing demand and is implemented by well-known vendors of control and drive technology, robotics and sensors. EtherCAT Technology Group (ETG) member Beckhoff Automation provides test cases and test tools as well as certification support for implementing the Safety over EtherCAT protocol. The parameterization software for the decentralized safety controller is part of the Beckhoff EtherCAT configurator ET9000, which also works with EtherCAT masters from other suppliers because of the system’s open interfaces.

Now additional suppliers complement Safety over EtherCAT with an all-around, care free package: At a press conference held by the EtherCAT Technology Group at the SPS/IPC/Drives 2010 show in Nuremberg, Germany, Dieter Hess, Managing Director of 3S-Smart Software Solutions GmbH, announced the support of the CoDeSys Safety editors for this decentralized safety controller. As a result, CoDeSys customers can enhance their control systems with functional safety without having to develop and certify their own safety controller. 3S-Smart Software Solutions GmbH will also implement Safety over EtherCAT in the company’s own safety control package.

The Safety over EtherCAT protocol stacks for master and slave devices were announced by IXXAT managing director Christian Schlegel. IXXAT not only offers the protocol software itself, but also supports its customers with implementing and certifying their Safety over EtherCAT devices.

Dr. Guido Beckmann, chairman of the ETG Technical Committee and safety expert with Beckhoff Automation, underlines the compactness and openness of the safety protocol: “Experience shows that code size and stack delays in Safety over EtherCAT are substantially lower than comparable protocols. The safety container of a minimal 6 bytes allows users to simply use the protocol on legacy fieldbus systems as well. And thanks to the manifold support offering it now becomes even easier to integrate Safety over EtherCAT in one’s product portfolio: “Make or Buy” – with Safety over EtherCAT, vendors now have a choice.”
EtherCAT sets new standards for real-time performance and topology flexibility, while meeting or undercutting traditional fieldbus cost levels. EtherCAT features include high precision device synchronization, cable redundancy options, and a functional safety protocol (SIL3). EtherCAT is an international standard (IEC, ISO and SEMI).
The protocol Safety-over-EtherCAT (FSoE) was specified for the transmission of safety relevant data. It is standardized in IEC 61784-3 Ed.2 and is used to send input information of safety sensors (such as safety light curtains or emergency stop buttons) to a safety logic controller. Based on these inputs, this controller computes the commands for the safe outputs (such as contactors or safety relevant drives) and thus controls the safety functionality of the machine.

ODVA Announces Formation of Vertical Market Special Interest Group for Rail Transport

ODVA announced that it will form a new special interest group to evolve ODVA technologies for rail transport. Aimed at enhancing ODVA’s specifications with services and device profiles to meet the needs of rail transport, the resulting standards are expected to provide a comprehensive solution for rail transport, encompassing on-board train controls, monitoring, signaling and demand-response. The formation of this special interest group (SIG) reflects increased interest in ODVA technologies by OEMs in the rail transport industry.

The strong business outlook for rail transport is driving increased investment by OEMs in information and communication technologies (ICT) such as the ODVA technology portfolio. ICT will be critical to the realization of improvements in safety and service in combination with market demands for increased rail capacity and higher performance equipment. The intimate connection of rail transport with key sectors of the economic ecosystem – industrial, retail, commercial, residential and government – mandates that future ICT implementations in rail transport adapt automation technologies that are open, interoperable and, whenever possible, embrace the use of commercial-off-the-shelf and standard, unmodified Internet and Ethernet technologies. All of these attributes are exemplified by ODVA and its cornerstone technologies, the Common Industrial Protocol and EtherNet/IP.

Pascal Cléré, vice president, Alstom Transport Information Solutions, and ODVA member, stated, “Broad-based deployment of Ethernet technologies is a key element of the product plans for Alstom’s Carborne range of systems, devices and services for the railway sector. Alstom is leading the market in the application of Ethernet for rail transport and was first to market in 2008 with an ATC control/command application in Beijing.

Now Alstom seeks to lead in the application of open Ethernet standards to this sector and believes that ODVA – with its core values of vendor-neutrality, open participation and open technologies – and EtherNet/IP – as the world’s leading industrial Ethernet network – together provide the ideal platform for building consensus within the railway transport industry around its next generation of global network standards based on Ethernet.”

“This is a new market sector for ODVA technologies, which ODVA is entering due to the interest of members,” added Katherine Voss, executive director of ODVA. “As one of ODVA’s vertical market SIGs, the Rail Transport SIG will provide a unique opportunity for leaders in the rail industry and information technology to collaborate for best-in-class, open and interoperable communication standards for the next generation in railway transport.”

openSAFETY now also available for PROFINET

After the introduction of openSAFETY solutions for SERCOS III, Modbus TCP, EtherNet TCP/IP and POWERLINK at last Hannover Messe exhibition, the openSAFETY standard is now also available for PROFINET.

[caption id="attachment_266" align="aligncenter" width="300" caption="openSAFETY now also available for PROFINET"]openSAFETY, PROFINET[/caption]

Thus, openSAFETY is now available for all major real-time Ethernet protocols, covering 91% of the Industrial Ethernet market. With its openSAFETY solution, the EPSG is the only provider of a ready-to-use safety technology running on all transport protocols.

openSAFETY has been developed independently from all fieldbus organizations. Since the development of safety-oriented technology is very cost-intensive and carries a high investment risk, the automation industry has been calling for a global standard for safety systems for a long time.

By introducing openSAFETY, the first completely open safety-oriented data transfer protocol for all automation applications, the Ethernet POWERLINK Standardization Group (EPSG) has laid the foundations. The protocol, which has been certified by German testing authorities TÜV Rheinland and TÜV Süd, allows for communication cycles at the microsecond level, thus ensuring very fast reaction times as well as optimal safety.

It is suitable for use in systems with safety requirements up to SIL 3.

POWERLINK Slave from B&R

In addition to service providers such as IXXAT, Hilscher and port, B&R now also offers a POWERLINK Slave based on Altera and Xilinx FPGAs.

Thanks to steadily decreasing hardware prices and no license requirements, prices for POWERLINK Slaves interfaces are up to 45% lower than for ASIC-based Industrial Ethernet systems with a comparable performance.

Apart from reference designs, B&R also provides support during design, business level maintenance and a POWERLINK testing system. Due to its high performance and low production costs, the POWERLINK Slave solution from B&R is equally suited for cost-sensitive products, such as compact sensors with few electronics, and for high-performance servo drives or modular I/O systems.

The new reference design does not require manufacturers to have previous experience with POWERLINK technology. The complete package also includes a simple API which can be used via a serial connection (SPI) or via a 8/16 bit microprocessor interface, allowing for the connection of any host processor (such as ARM, x86 or DSPs) to a POWERLINK network.

Simple sensors do not require an external microcontroller and can be directly connected to the POWERLINK Slave FPGA, thereby further reducing overall costs.

Bihl+Wiedemann connects AS-i Safety at Work and openSAFETY

Bihl+Wiedemann, one of the leading companies in the development and implementation of electronic automation components and safety solutions with an AS-interface, will launch a safe gateway for AS-i Safety at Work systems and openSAFETY.

[caption id="attachment_258" align="aligncenter" width="273" caption="Bihl+Wiedemann becomes a member of the EPSG"]Bihl+Wiedemann, EPSG, POWERLINK[/caption]

Also, Bihl+Wiedemann becomes a member of the EPSG. The gateway enables both non-safe diagnosis data and safety-related process data to be exchanged between AS-interface installations and openSAFETY. On the AS-i side, the gateway provides an AS-i Master with an integrated safety monitor.

Due to its simple installation and low costs, AS-interface technology is widely used. More than a hundred companies provide more than a thousand different products. With AS-i Safety at Work, safety-oriented sensors and actuators in openSAFETY applications can also benefit from the advantages of AS-i.

For openSAFETY, the gateway constitutes a safe I/O node with a variable number of safe input and output signals. The number of signals is determined by the AS-i configuration. On the occasion of this development, Bihl+Wiedemann has decided to join the EPSG.

“The combination of AS-interface – the tried-and-proven, simple, and inexpensive installation system for the lowest field level – and openSAFETY is very attractive to us”, said Jochen Bihl, CEO of Bihl+Wiedemann. “Since AS-i Safety complements every open safe fieldbus technology, joining the EPSG was the logical conclusion.”
