Description
Decentralized automation tasks require rugged hardware capable of operating outside traditional control cabinets. The Beckhoff IP3112-B518 Fieldbus Box meets this demand by providing direct connection of peripheral signals to CANopen networks in harsh industrial environments. By housing the communication and I/O interface in a compact, environmentally sealed module, this device minimizes cabling effort and reduces cabinet space requirements.
Operating as a high-performance CANopen node, the IP3112-B518 supports up to 16 send and 16 receive Process Data Objects (PDOs), enabling highly flexible data transmission. It features advanced CANopen communication profiles including life guarding, node guarding, emergency object handling, variable mapping, and store/restore parameters. Configuration can be executed either via the KS2000 service software or directly from the master controller using Service Data Objects (SDOs). The integrated M12 T-connector simplifies bus cabling by allowing direct loop-through of the network medium without additional external splitters.
Features
- Direct integration into CANopen industrial networks.
- Supports up to 16 send and 16 receive Process Data Objects (PDOs) for flexible data mapping.
- Automatic detection of network data transfer rates from 10 kbaud up to 1 Mbaud.
- Robust environmental protection class IP65, IP66, and IP67, enabling cabinet-free mounting.
- Integrated M12 T-connector interface for efficient bus wiring and daisy-chaining.
- Comprehensive diagnostics via built-in node guarding, life guarding, and emergency object services.
Applications
- Automotive manufacturing and assembly lines.
- Material handling systems and industrial conveyors.
- Wastewater treatment facilities.
- Food processing and packaging machinery.
- Distributed sensor/actuator networks in heavy machine manufacturing.

Installation Guidelines
- Ensure the unit is mounted on a flat, vibration-resistant surface using the designated mounting holes.
- Tighten all unused M12 and M8 connection ports with verified protective caps to maintain the IP67 sealing integrity.
- Route bus lines and power cables separately from high-voltage motor or drive cabling to avoid electromagnetic interference.
- Ensure correct termination of the CANopen network by installing a 120-Ohm terminating resistor at both physical ends of the bus segment.
