ASi-5 Modules for CAN and Modbus TCP Integration

The new hardware solutions facilitate the integration of CAN and Modbus TCP devices into industrial automation systems and manufacturing environments. These active modules streamline field-level communication without requiring specialized firmware or predefined device profiles.

System Integration Without Specialized Firmware
The BWU4412 and BWU5246 ASi-5 modules are engineered to connect standard field devices into existing networks. By bypassing the need for dedicated firmware, this technology reduces configuration overhead and efficiently accommodates specific individual requirements in automation applications.

Configurable Modbus TCP Communication
The BWU5246 functions as an ASi-5 active distributor designed specifically for Modbus TCP devices. Enclosed in an IP67-rated housing, the module supports individually configurable data exchange. Network parameters can be configured via PC software, enabling the flexible integration of any standard Modbus TCP hardware.

Transparent CAN Data Transmission
For CAN network architectures, the BWU4412 module enables 100% transparent communication within an IP67-rated enclosure. The hardware transmits the complete CAN frame directly into the process data stream. This transmission preserves all frame information, including the CAN ID and data length, ensuring flexible integration of diverse CAN devices. The BWU4412 also incorporates four digital inputs and two digital outputs to process additional auxiliary signals.

In the industrial networking sector, integrating distinct fieldbus and Ethernet protocols typically requires dedicated standalone gateways or complex PLC communication processors. Devices like HMS Anybus Communicators or Turck multiprotocol block I/Os serve similar functions by translating Modbus TCP or CAN data for higher-level networks. However, the direct integration of these protocols into the ASi-5 layer via IP67 modules—such as the BWU4412 and BWU5246—shifts the translation closer to the field level. Traditional gateways often require installation inside IP20 control cabinets, whereas IP67-rated ASi-5 modules permit decentralized machine-mount installations, reducing wiring costs and cabinet space requirements. Furthermore, transparent transmission of complete CAN frames directly into process data avoids the latency and truncation risks associated with intermediate protocol conversion mapping.
