Beckhoff EP6002-0002 EtherCAT Box Serial Interface Module

Description

Industrial serial communication tasks demanding IP67-level environmental protection are directly addressed by the Beckhoff EP6002-0002 serial interface module. This ruggedized EtherCAT Box enables the decentralized integration of up to two serial end devices directly in the field, bypassing the need for protective control cabinets. Each of the two channels can be configured independently, allowing simultaneous operation of RS232, RS422, or RS485 protocols. The module executes rapid, bi-directional data transfer to the controller via the high-performance EtherCAT protocol, establishing an efficient interface for bar code scanners, operator terminals, serial sensors, and legacy industrial devices.

The transmission parameters, including baud rates up to 115,200 baud, parity, and stop bits, are software-selectable to match diverse device requirements. To prevent signal interference and isolate delicate terminal equipment, the EP6002-0002 features integrated 500 V electrical isolation between the communication interfaces and the internal EtherCAT system logic. Encased in a compact, field-ready housing with a high ingress rating, it supports flexible mounting and straightforward integration into highly distributed factory automation topologies.

Features

• Dual-channel design supporting independent interface selection (RS232, RS422, or RS485) per channel.
• Direct integration into high-speed EtherCAT networks via dual M8 shielded connection ports.
• Generous onboard data buffering with an 864-byte receive buffer and 128-byte transmit buffer per channel.
• Electrically isolated, short-circuit proof +5 V DC auxiliary sensor power supply (20 mA per channel).
• Robust IP65/66/67 protection rating for direct machine mounting in harsh industrial environments.
• High-quality M12 connector interfaces ensuring secure, vibration-resistant connections for serial peripherals.

Applications

• Decentralized barcode reader and RFID scanner integration on material handling conveyors.
• Field connection of serial weight indicators and industrial scales in packaging systems.
• Direct interfacing with legacy variable speed drives and positioning systems using Modbus RTU (via RS485).
• Connecting operator panels, serial displays, and diagnostic terminals in process plant layouts.

Installation Guidelines

• Mounting: Mount the unit directly onto a flat, even surface using standard M3 bolts through the designated mounting holes. Do not exceed the maximum mounting torque.
• Grounding and Shielding: Ensure the module is properly grounded. Use shielded M8 and M12 cables to maintain high electromagnetic compatibility (EMC) standards and minimize signal noise.
• Cable Tightening: Hand-tighten all M8 and M12 circular connectors to ensure internal seals are compressed. Torque to nominal OEM recommendations to preserve the IP67 ingress protection rating.
• Power Distribution: Observe voltage drops when daisy-chaining multiple modules via the M8 power loop. Do not exceed the maximum current carrying capacities of the power connections.
