EtherCAT P: The one cable solution – One step closer to automation without control cabinets

EtherCAT P: The one cable solution – One step closer to automation without control cabinets

The EPP1258-0001 EtherCAT P Box with digital inputs acquires fast binary control signals from the process level and transmits them, electrically isolated, to the controller. The signals 0 and 1 are furnished with a timestamp that shows the time of the last edge change with a resolution of 1 ns. With this technology, signal curves can be traced exactly in time and correlated with the distributed clocks system-wide. With this technology, machine-wide parallel hardware wiring of digital inputs or encoder signals for synchronization purposes is often no longer required. As a result, responses with equidistant time intervals, independent of the bus cycle time, are to a large extent possible.
