One cable solution for automation in processing factories

摘要

The One Cable Automation (OCA) philosophy from Beckhoff is based on the connection of individual field devices, decentralised terminal boxes, and machine modules using only one cable. This cable technology combines ultra-fast communication via EtherCAT, with the power supply required by the connected components. For the 24V field level, this was implemented using the EtherCAT P technology expansion connected via special M8 connectors, To provide additional power supply capabilities via a one cable solution, Beckhoff developed the new ENP and ECP connector families. These combine EtherCAT or EtherCAT P communication with additional power conductors in one cable, and are easy to use, mechanically coded to prevent installation errors and offer a high waterproof rating of IP67.
