Description

Designed for decentralized industrial automation networks, the IL2301-B310 functions as a robust PROFIBUS DP coupler box within the Beckhoff Fieldbus Box range. This high-performance module serves as an IP-Link gateway, allowing standard decentralized extension modules to interface directly with a PROFIBUS DP fieldbus network. Built to operate in harsh machine-level environments, this coupler box eliminates the need for protective control cabinets by integrating advanced diagnostic functions and rugged hardware routing directly onto the machine frame.

The module automatically detects transfer rates up to 12 Mbaud and supports DP-V1 extensions, providing flexible integration options and precise parameterization via the Beckhoff KS2000 configuration software or the master PLC controller. This ensures optimal communication efficiency and minimal configuration overhead in complex multi-node network topologies.

Features

  • Automatic baud rate detection up to 12 Mbaud for seamless network integration.
  • Hardened industrial housing rated at IP65, IP66, and IP67 for direct wet and dusty environment placement.
  • Integrated IP-Link fiber-optic interface for high-speed localized system expansion.
  • Support for DP-V1 extensions enabling sophisticated parameterization and advanced diagnostic workflows.
  • Compact M12 interface for reliable PROFIBUS DP connection and minimized physical footprint.
  • M8 power supply design with upstream feed and downstream loop-through connections.

Applications

  • Automotive manufacturing and assembly lines.
  • High-speed packaging machinery and sorting systems.
  • Material handling conveyor systems.
  • Food and beverage production facilities requiring frequent high-pressure washdowns.

Installation Guidelines

  • Securely mount the module directly to the machinery frame or mounting plate using appropriate M4 screws.
  • Ensure all M12 and M8 protective caps or cables are fully tightened to a torque specified for IP67 compliance.
  • Maintain a minimum bending radius for the IP-Link fiber-optic connection cables to avoid signal degradation.
  • Use shielded, twisted-pair copper cables for PROFIBUS connections to protect against electromagnetic interference.

FAQ

What is the primary function of the Beckhoff IL2301-B310?

The Beckhoff IL2301-B310 is a PROFIBUS DP coupler box that acts as a decentralized gateway, linking localized IP-Link extension I/O modules directly to a PROFIBUS DP fieldbus system.

Does the IL2301-B310 support DP-V1 extensions?

Yes, this coupler box fully supports DP-V1 extensions, allowing for advanced parameterization, configuration, and diagnostics via KS2000 software or the master controller.

What is the environmental rating of the IL2301-B310?

The module features an IP65, IP66, and IP67 protection rating, meaning it is dust-tight and resistant to high-pressure water jets, enabling direct machine-mount installations.
