BECKHOFF EPP1111-0000 EtherCAT P Box ID Switch Module

Product Overview

The EPP1111-0000 (EPP1111-0000) is an industrial-grade EtherCAT P Box designed for the decentralized identification of specific EtherCAT groups within a larger network topology. Encased in a rugged polyamide housing, this machine-mountable I/O block allows system integrators to assign unique identifiers to modular machine sections or hot-swappable tool assemblies.

By enabling automated group recognition directly on the machine frame, the module facilitates flexible topology configurations and rapid tool changes. This capability prevents configuration mismatches in complex assembly cells, material handling systems, and robotic end-effectors, actively reducing commissioning time and dropping unexpected system downtime.

Topology Identification and Functional Design

The EPP1111-0000 operates within the EtherCAT P system framework, utilizing a single cable connection that simultaneously carries high-speed 100 Mbit/s Fast Ethernet data and 24 V DC system power. The physical interface is equipped with two P-coded, shielded M8 screw-type connectors to enforce proper wiring alignment and preserve signal integrity under high electromagnetic stress.

The module serves as a static node identifier that requires zero software or hardware configuration tools during physical installation. Its primary task is reading and transmitting the group ID to the master controller via standard EtherCAT cable over distances up to 100 meters between stations, ensuring reliable deterministic synchronization across expansive production footprints.

Technical Specifications

Product FAQs

How does the EPP1111-0000 identify separate groups without manual configuration settings?

The module is detected natively by the EtherCAT master during the network boot scan. It transmits a factory-set or hardware-defined position value directly into the master process image, allowing the control software to verify the machine topology layout and map downstream slave devices based on the group ID.

What is the practical benefit of P-coded M8 connectors over standard EtherCAT connectors?

P-coding integrates EtherCAT communication and the 24 V DC power supply lines into a single, compact M8 interface. This layout eliminates the need for separate communication and power cables, reducing field wiring complexity, cutting down material costs, and minimizing connection failure points.

Can this module be mounted directly onto a machine frame without an electrical control cabinet?

Yes. With an IP65, IP66, and IP67 ingress protection rating, the module's polycarbonate/polyamide housing is entirely sealed against dust, oil, and direct water jets. It is designed specifically for direct on-machine mounting in wet, dirty, or space-constrained industrial zones.

Decentralized Installation and Environmental Safety Guide

• Mechanical Fastening and Alignment: Mount the box module directly to the machine structure using the two integrated 3.5 mm diameter fixing holes. Use standard M3 screws tightened to a maximum torque specification of 0.6 Nm to avoid cracking the polyamide housing. The module supports variable installation positions to accommodate flexible machine routing paths.

• M8 Connector Torque and Sealing: To guarantee the IP67 protection rating, all connected M8 P-coded plugs must be tightened using an industrial torque wrench set exactly to 0.4 Nm. Leftover or unused M8 ports must be sealed with official, moisture-proof protective caps. Failure to seal empty sockets allows moisture ingress, leading to short circuits and communication timeouts.

• Cable Routing and Bending Radii: When routing EtherCAT P cables across moving joints or robotic arms, maintain the manufacturer-specified minimum bending radius for high-flex lines. Separate the communication cables from heavy variable frequency drive (VFD) power cables by at least 10 cm to suppress external cross-talk, ensuring uninterrupted 100 Mbit/s transmission speed.
