Product Information:A-B 1756-CNBR/E ControlLogix Communication Module
The Allen-Bradley 1756-CNBR/E is a ControlLogix ControlNet Redundant Bridge Module Series E. It is a high-performance module that provides a redundant connection between two ControlNet networks. The 1756-CNBR/E supports both ring and linear topologies, and it can be used to create a redundant backbone for a ControlLogix system.
Product description:
The 1756-CNBR/E is a full-duplex bridge that supports data rates up to 100 Mbps. It has two ControlNet ports, each with its own independent processor and memory. The 1756-CNBR/E also has a diagnostic port that can be used to monitor the status of the module and the ControlNet networks.
Product parameters:
- Data rate: 100 Mbps
- Topology: Ring or linear
- Port type: ControlNet
- Diagnostic port: Yes
- Dimensions: 4.5 x 2.8 x 0.8 inches (114.3 x 71.1 x 20.3 mm)
- Weight: 0.5 pounds (0.23 kg)
Usage methods:
The 1756-CNBR/E is typically used to create a redundant connection between two ControlNet networks. This can be done by connecting the two ports of the 1756-CNBR/E to the two ControlNet networks. The 1756-CNBR/E will then automatically route traffic between the two networks.
The 1756-CNBR/E can also be used to create a redundant backbone for a ControlLogix system. This can be done by connecting the two ports of the 1756-CNBR/E to two different ControlLogix controllers. The 1756-CNBR/E will then automatically route traffic between the two controllers.
Product advantages:
The 1756-CNBR/E offers a number of advantages, including:
- High performance: The 1756-CNBR/E supports data rates up to 100 Mbps, making it one of the fastest ControlNet bridges available.
- Reliability: The 1756-CNBR/E is a full-duplex bridge with two independent processors and memory. This makes it very reliable, even in the event of a failure of one of the processors or memory modules.
- Flexibility: The 1756-CNBR/E supports both ring and linear topologies. This makes it flexible enough to be used in a variety of applications.
Overall, the Allen-Bradley 1756-CNBR/E is a high-performance, reliable, and flexible ControlNet bridge that is ideal for creating redundant connections between ControlNet networks or for creating a redundant backbone for a ControlLogix system.
