Control Simplicity, Flexibility

Controller Suppliers Offer Ease and Flexibility at Lower Costs

By Control Design Staff

Manufacturers increasingly demand more flexible machines that are able to switch jobs easily and expand with growing business. Controllers of all kinds are focused on increased flexibility, as well as simplicity.

Although the market is flooded with configurable safety controllers that can get the job done, flexibility is difficult to come by at a low cost, according to Helge Hornis, manager of the Intelligent Systems Group at Pepperl+Fuchs. "Most of the higher-end solutions are too complex and costly for all but the largest and most difficult applications, while low-end controllers lack the necessary flexibility to adapt when application requirements change, even just a little," he says. "And no matter how well a system is planned out, things happen and needs change."

Pepperl+Fuchs has created programmable safety controllers that make it easier to add safe inputs and outputs as needed, Hornis says.

Omron Scientific Technologies (STI) has also focused on simplifying safety control, creating software-based standalone controllers that aren't hardwired into the control system. "Users will benefit from previously unavailable levels of safety system flexibility by quickly and easily reconfiguring the unit when new safety features are added to their setup," says Kenji Kawasaki, product manager at Omron STI.

Eaton has been adding Controller Development System (CoDeSys) software to more of its North American products to help increase the level of flexibility, including its latest PLCs. The CoDeSys development software is an open programming environment, notes Richard Chung, product manager. The controllers provide flexible, scalable design, so they are able to create custom automation systems, he adds.
