Transitioning from Fieldbus to Ethernet: Benefits and Requirements for the Plant Floor
Industrial Ethernet offers a number of advantages over fieldbus networks, and can play well with existing fieldbus networks. Learn about strategies for switching, as well as what to look for when contemplating the switch.
While any kind of change can be cause for concern, the transition from fieldbus to Ethernet doesn't have to be disruptive. While some Industrial Ethernet implementations will require some detailed architectural changes, others make the process far simpler.
Technologies now exist that enable companies to simply install Industrial Ethernet for new plants or lines, and seamlessly connect them with existing fieldbus networks. Benefits include greater speed, improved troubleshooting, simpler integration, and wireless capabilities... Read more
Latest Safety Trend: Integrating Safety with Motion Control
Combining formerly separate functions on one device results in easier installation and implementation, reduced footprint, and lower costs.
Newest controller technology combines PLCopen-compatible motion control blocks for coupled motion sequences of multiple axes with pre-configured TÜV-certified library blocks, for key safety functions such as emergency stop, two-hand control, muting, and door monitoring... Read more
