EtherCAT P – ultra-fast communication and power in one cable

The one cable solution – one step closer to automation without control cabinets

With EtherCAT P, Beckhoff combines communication and power in a single 4-wire standard Ethernet cable. The 24 V DC supply of the EtherCAT P slaves and of the connected sensors and actuators is integrated: US (system and sensor supply) and UP (peripheral voltage for actuators) are electrically isolated from each other and can each supply a current of up to 3 A to the connected components. At the same time, all the benefits of EtherCAT, such as freedom in topology design, high speed, optimum bandwidth utilization, telegram processing on-the-fly, highly precise synchronization, extensive diagnostics functionality, etc., are all retained.

The currents of US and UP are coupled directly into the wires of the 100 Mbit/s line, enabling the realization of a highly cost-effective and compact connection. EtherCAT P offers benefits both for connecting smaller, remote I/O stations in the terminal box and for decentralized I/O components locally in the process. A connector family was specially developed for EtherCAT P, in order to prevent potential damage caused by incorrect connection with standard EtherCAT slaves. It covers all applications from the 24 V I/O level up to drives with 630 V AC or 850 V DC and a current of up to 72 A.

EtherCAT P offers extensive savings potential:

  • optimized for direct connection of EtherCAT P devices in the field
  • time savings through lower wiring effort
  • fewer errors
  • smaller sensors and actuators through the elimination of separate supply cables
  • simple connection of components

As usual with EtherCAT, users benefit from the choice of topology and can combine line, star and tree structures with one another in order to achieve the least expensive and best possible layout of their system. Unlike classic Power over Ethernet (PoE), devices can be cascaded in EtherCAT P and supplied with power from one power supply unit.

When designing a machine, the individual consumers, cable lengths and cable types are configured with tool assistance and this information is used to create the optimum layout of the EtherCAT P network. Since it is known what sensors and actuators will be connected and which ones will be operated simultaneously, the power consumption can be accounted for accordingly. For example, if two actuators never switch simultaneously from a logical point of view, they also never need the full load simultaneously. The result is further savings potential in terms of the required supplies and power supply units.

System overview for IP20 and IP67

As usual with EtherCAT, users benefit from the choice of topology and can combine line, star and tree structures with one another in order to achieve the least expensive and best possible layout of their system. Unlike classic Power over Ethernet (PoE), devices can be cascaded in EtherCAT P and supplied with power from one power supply unit.

The EK13xx EtherCAT P Couplers with IP20 rating enable the use of EtherCAT P from the control cabinet right to the machine:

  • the EK1300 coupler with a second M8 socket, P-coded, for continuation of the topology,
  • the 2-port EK1322 EtherCAT P junction (with feed-in) enables configuration of EtherCAT P star topologies,
  • the 1-port EK1310 EtherCAT P extension (with feed-in) enables conversion from EtherCAT to EtherCAT P.

The EPPxxxx EtherCAT P Box modules with IP67 rating cover the typical range of requirements for I/O signals:

  • digital inputs (3.0 ms or 10 μs filter),
  • digital outputs with 0.5 A output current,
  • combination modules with digital inputs and outputs,
  • analog inputs and outputs with 16-bit resolution, thermocouple and RTD inputs.

The EPP13xx EtherCAT P junctions are available for flexible topology configurations. The current carrying capacity of 3 A per EtherCAT P segment already enables a wide range of sensors/actuators to be used. If a power supply boost is required, the EPP1332-0001 EtherCAT P junction can be used to feed in both US and UP at any point. The EPP1342-0001 should be used for branches without voltage refresh.
