Safety: The New Differentiator in Automation Networks
Digital safety networks used in OEM machinery and discrete manufacturing production lines are the new frontier of differentiation in the automation network marketplace. Drawing on legacy battles in areas such as serial-based device networks, process fieldbuses, and Ethernet-based automation networks, suppliers and network trade associations alike are ramping up their arsenals for competition in this increasingly important arena.
Functional or machine safety is an important issue facing every supplier of factory automation devices. As the networks associated with functional safety emerge as the next battleground, every supplier will have to have a strategy in this realm.
The factory automation safety network landscape is evolving from its origins in dedicated safety networks to one where safety protocols are increasingly added to existing automation control networks. Safe versions of industrial networks are now available, allowing a single bus to support both standard and safety-related messages and eliminating the need for a separate safety bus. Similarly, embedding a safety controller and safe I/O into a servo drive eliminates the need for a separate safety controller and I/O and enables controlled or limited shutdowns and reduced downtime.
Strategic Issues
Users are exhibiting a cautious optimism toward intelligent pumps. Nevertheless, suppliers believe it is not a question of IF, but WHEN they will catch on. In order to help their cause, suppliers must increase their value proposition to users. This study will help to answer questions, such as:
- What is the future for Ethernet-based versus serial safety networks?
- What is the growth outlook for OEM machinery vs. production lines?
- How deep into the motion control market will safety networks penetrate?
- What business benefits should be emphasized in a TCO-based sales approach?
- What role do standards and certifications play?
