It's becoming a wireless world. But while high data rate wireless standards like Wi-Fi and WiMax have been grabbing the headlines, the market for low data rate wireless could turn out to be even bigger. The US-based standards body IEEE organised a task group to develop a standard for low power, low data rate networks. As a result, the ZigBee Alliance was set up by a number of companies to work together to build on 802.15.4. However, a rival technology to ZigBee, called Z-Wave, has received the support of chip giant Intel, as well as networking heavyweight Cisco. In many ways, Z-Wave and ZigBee are similar. Both are wireless standards. Both use mesh networks. Both are designed for low power. Though ZigBee provides for a higher data rate than Z-Wave, both standards provide for relatively low throughput. But proponents of ZigBee claim that Z-Wave is considerably less robust. - Author(s): P. Lee

Power over Ethernet (PoE) brings a host of benefits to the design, implementation and long-term usability of wired Ethernet local area networks (LANs). Cost, flexibility and even safety are all enhanced. It overcomes the major limitation that system designers often encounter whereby they must locate powered network devices within close proximity to AC power outlets. With PoE, both data and power at a safe nominal 48VDC are carried over the same Ethernet cable. To take full advantage of PoE, the network devices will also be required to handle the hand-shaking process that allows the network hub to recognise a device as being PoE enabled and understand and manage its specific power needs. - Author(s): R.

The growth of Ethernet/IP is in part due to the growing realisation that it can perform real-time control. Networks utilised in manufacturing have traditionally been optimised for performance in specific applications; commonly device, control and information in the automation network paradigm. The recent addition of safety to automation networking required the integration of a separate subsystem. In today's networks, common application layers are the key to advanced communication and true network integration. The Common Industrial Protocol (CIP) allows complete integration of control with information, multiple CIP networks and Internet technologies. Built on a single, media-independent platform, CIP provides seamless communication from the plant floor throughout the enterprise, with a scalable and coherent architecture. CIP allows companies to integrate I/O control, device configuration and data collection across multiple networks. This ultimately minimises engineering and installation time and costs while maximising return on investment (ROI). - Author(s): D. James

Batch processes, by their very nature, are rarely in a steady state for any great length of time. This constant change of plant and process state results in a level of complexity of the automation of the process that is not found in continuous processes such as refining. Applying the principles of batch automation and selecting a suitable control system and supplier is only part of the story. Managing a batch automation project requires considerations over and above those needed for the automation of a continuous process plant. - Author(s): S. Davies

There has been a growing realisation for some time that there is a void in the manufacturing software arena. This void, or middle ground, sits below the high level enterprise resource management (ERP) systems that provide top-level information and the shop-floor control systems. The ERP companies have been dipping their toes in the arena either with their own products, partnerships or acquisitions, while typical control and automation vendors, who already harvest the real-time data that makes these middle ground systems so attractive, are reaching up to provide solutions. One such company is Rockwell Automation. Kevin Roach, vice president, Rockwell Software, takes us through the Rockwell strategy and describes the company's new FactoryTalk suite. - Author(s): S.

Connecting the information 'gap' between production level machines and processes with the management level is the goal of many manufacturing companies. Why? Because achieving this kind of visibility of key production data enables managers to make better, more informed decisions at the right times, in response to fast-changing conditions out on the shop floor and from customers. In this article, we look at how Ethernet converter devices are helping to solve production planning and data visualisation problems for one of Europe's largest tobacco manufacturers. - Source: Computing and Control Engineering, Volume 17, Issue 6, p. 46 –47

Alliances are an essential means for a company to punch above its weight. Engineering businesses which are most profitable, flexible and forward thinking, have a large portfolio of alliance partners that can be drawn upon as and when required; a pool of expertise and talent spanning a range of sectors. Recently, statistics claims that as many as 50% of all alliances in the engineering sector fail within the first six months. We discuss the reasons behind this failure.
