Yokogawa BUS2 Communication Bridge Module

Configured for high-speed data transmission and remote I/O processing in Yokogawa DCS networks, the Yokogawa BUS2 (BUS2 Communication Bridge Module) provides direct physical/electrical execution. Hardware Specifications Parameter Specification Model BUS2 Brand Yokogawa Origin Unspecified Weight Unspecified Dimensions Unspecified Operating Temp Standard industrial limits Power Consumption Unspecified Function CPU to remote I/O communication bridge Network Topology Daisy-chain or star network configurations Drop Count Capability Supports extended node counts exceeding 32 drops Channel-to-Channel Isolation and 4-20 mA HART Loop Protocol The module incorporates channel-to-channel isolation hardware to shield internal processing buses from transient electrical noise and potential earth loops across long-distance cable runs. Communication pathways support integration with 4-20 mA HART loop protocols and distributed control fieldbus networks, ensuring deterministic data exchange and stable signal conditioning across remote node interfaces. Frequently Asked Questions Q: What is the maximum node drop capacity supported by the BUS2 communication bridge network architecture? A: The module supports extended network configurations capable of handling node counts exceeding 32 drops in daisy-chain or star topologies. Q: How does the module handle communication line disturbances during primary path failure? A: Built-in hardware-level redundancy mechanisms and cyclic error-checking algorithms execute automatic failover protocols to maintain deterministic loop timing. Field Installation Guidelines Verify that network termination resistors are correctly matched to the physical cable impedance prior to energizing the bus lines. Ensure shield drain wires are grounded at a single, low-impedance reference point to prevent electromagnetic interference coupling along long-distance cable runs. Maintain adequate physical clearance around the unit within control enclosures to support natural convective cooling. Inspect all backplane and terminal block connectors for oxidation or mechanical misalignment before final slot insertion.
