Controllers: More of Everything

May 17, 2013
The List of User Requirements Continues to Grow Longer

The latest influences on the design of programmable controllers go beyond the ever-present need for faster and more powerful processing.

"That means integration of Ethernet and protocols, integrated support of some IT functionality, more memory on the controller itself for data logging, and easier handling of web-based HMIs," says Dan Fenton, product marketing specialist for Phoenix Contact. "In addition, software is beginning to matter more, as IEC 61131 is becoming more important in customer specifications, in particular for openness and flexibility."

Remote machine connectivity is becoming more important, whether for an OEM/SI to reduce maintenance/travel costs, or for the end user to reduce downtime/improve logistics," adds Cindy Hollenbeck, vice president sales/marketing at SoftPLC. "Low-cost, M2M cellular plans and cloud-based technology are making remote connectivity almost a no-brainer in terms of cost."

"For the past few years, the market has pushed on physically downsizing PLCs and other control components," argues Charlie Norz, product manager at Wago. "Fortunately, advances in board-level electronics enable PLC power and capabilities to grow. Our Ethernet 2.0 PLC line up mirrors this trend as each PLC is up to five times smaller than conventional devices."

Paul Marsden, global technology manager for HMI at Kontron, says total sales of industrial PCs are projected to rise to an estimated $3.8 billion by 2016, which equates to a 8.5% CAGR. "Market trends demonstrate the replacement of analog resistive displays for projected capacitive touch displays, Windows XP being displaced by Windows 7, a rapid removal of legacy products, a rise in system reliability and reduced costs of ownership," Marsden says.

"Builders of standalone machines want world-class micro PLCs with flexible, 'just-enough' control that helps them differentiate their machines from the competition," argues Thomas Sugimoto, product marketing manager for Micro800 at Rockwell Automation. "But those PLCs must be economical from a holistic perspective. Machine builders know better than anyone the true, total cost of designing, developing and delivering machines. Their holistic perspective includes flexible hardware configurations, like USB; up to six serial ports and Ethernet for communications; up to 3-axes of embedded motion; plug-ins and 2085 expansion for I/O USB; and single programming software that eases installation, configuration, connectivity and maintenance."
