Product Summary
The 1768-CNB is an Allen‑Bradley CompactLogix communication module connecting to ControlNet networks. It handles up to 48 simultaneous connections and 99 nodes. This module excels in media redundancy, intrinsic safety, and high‑speed data transfers for redundant controller systems. Its rugged design ensures reliable operation in demanding industrial environments.
Theme A: Procurement & Buyer Guide
Procurement managers need precise technical alignment. The 48 connections and 99 nodes meet medium‑scale ControlNet demands. Engineers appreciate the 5 Mbps communication rate for deterministic I/O and messaging. This module occupies just one slot and draws 1 A at 5 V backplane current.
The power dissipation of 5.14 W minimizes heat inside the enclosure. Thermal dissipation is only 17.5 BTU/hr. These specs allow placement in sealed cabinets without extra cooling. The operating range from 0 to 60 °C suits most factory floors.

This module supports both BNC non‑redundant media and an RJ‑45 NAP connector. Use the NAP for network access port connectivity. The weight is just 0.26 kg, simplifying DIN‑rail or panel mounting. Choose this model for applications needing high reliability and fast data transfers.
Theme B: Step‑by‑Step Installation Guide
Begin by powering down the CompactLogix chassis. Insert the 1768-CNB into any slot 1 through 4. Secure it with the retaining screws. The slot width is one, so no extra space is needed. Connect the ControlNet trunk cable to the BNC connector for non‑redundant media.
Attach the NAP cable using a shielded RJ‑45 connector. Ensure the shield connects to the module’s ground. For redundant media, use two BNC connectors. The module supports up to 99 nodes on the same network. Set node addresses via RSLogix 5000 software.
Mount the module on a DIN rail or directly to a panel. The dimensions are 132 x 56.7 x 105.1 mm. Verify the operating temperature stays within 0–60 °C. Avoid condensation by keeping relative humidity below 95% non‑condensing.
Power up the system and confirm the module status LED is steady green. Configure the communication rate to 5 Mbps. This module handles up to 48 connections simultaneously. Test connectivity by sending a data packet from the controller.
