A-B 1756-CNBR
Product Name: Allen-Bradley 1756-CNBR ControlNet Bridge Module
Product Description:
The Allen-Bradley 1756-CNBR is a ControlNet bridge module designed for the ControlLogix platform. This module allows communication between two ControlNet networks, enabling the expansion of a ControlNet system or the connection of separate ControlNet segments. It facilitates the transfer of real-time control data between different areas of a plant or machine. The 1756-CNBR supports scheduled and unscheduled messaging across the ControlNet network. It installs directly into any slot of a ControlLogix chassis.
Key Characteristics:
- ControlNet Bridging: Connects two independent ControlNet networks.
- Scheduled and Unscheduled Messaging: Supports both time-critical control data and general data exchange.
- High-Speed Communication: Operates at the ControlNet data rate (5 Mbps).
- Redundancy Options: Supports redundant media and redundant power supplies for increased network availability.
- Configuration via Software: Network configuration and parameters are set through programming software.
- Diagnostic Indicators: Features LEDs for monitoring network status and module health.
- Chassis-Based: Installs directly into a ControlLogix chassis.
