Information About 1756-CNB
The 1756-CNB is part of the Allen-Bradley ControlLogix series, designed to bridge communication between the ControlLogix backplane and a ControlNet network. It operates at a ControlNet communication rate of 5 Mbps and supports up to 99 nodes and 64 bidirectional connections, which can include both scheduled and unscheduled data. This module is suitable for applications requiring up to 40–48 Logix connections per communication module and ensures seamless routing of I/O and messaging data. Featuring one BNC connector and one RJ-45 NAP port, it simplifies network integration and setup through selectable node addresses from 01 to 99. With a compact 1-slot width, a current draw of 970 mA at 5.1 VDC, and a thermal dissipation of 17.4 BTU/hr, the module delivers efficient operation while maintaining system reliability.
Key Features:
- Module Type: ControlLogix ControlNet Bridge module for ControlNet integration.
- Communication Speed: Operates at 5 Mbps for high-speed data transfer.
- Node Capacity: Supports up to 99 nodes for scalable network setups.
- Connection Capacity: Handles up to 64 bidirectional connections (scheduled and unscheduled).
- Ports: Includes 1 BNC connector for non-redundant media and 1 RJ-45 NAP port.
- Message Handling: Provides up to 20 buffers for unconnected messages.
- Current Draw: 970 mA at 5.1 VDC and 1.7 mA at 24 VDC for power-efficient use.
- Dissipation: Rated at 5.1 W power dissipation and 17.4 BTU/hr thermal output.
- Slot Requirement: Occupies a single slot in a ControlLogix chassis for compact installation.
- Configuration: Standard non-redundant operation with selectable node addresses from 01–99.
The 1756-CNB delivers the reliability and scalability required for ControlNet communication in ControlLogix-based automation systems.
