1783-BMS20CA | Allen-Bradley Stratix 5700 Ethernet Switch, 18-Port w/2-SFP

The Allen-Bradley 1783-BMS20CA is a managed industrial Ethernet switch designed for robust network communication in automation environments. It supports deterministic data transfer across industrial protocols such as EtherNet/IP. With its combination of copper, fiber, and combo ports, it allows flexible integration into diverse network topologies. The switch provides features such as VLAN support, QoS, IGMP snooping, and security management. Its integration with Studio 5000 simplifies configuration and diagnostics for Rockwell-based systems.

Yes, the 1783-BMS20CA supports expansion through the use of the 1784-SD1 Secure Digital memory card. This card can be used to store configuration files, logs, and diagnostic data. Memory expansion is useful for backup/restore operations and rapid device replacement. The SD card slot simplifies cloning and deployment across multiple switches. This makes the device adaptable for both single-use and fleet-wide deployments.

The 1783-BMS20CA is a fully managed Layer 2 Ethernet switch with features like VLANs, Quality of Service (QoS), port mirroring, IGMP snooping, and SNMP support. It can be managed via web interface, CLI (command line), or through Studio 5000 Add-On Profiles. Security features include port-based access control and MAC filtering. Network diagnostics are enhanced with port statistics and event logging. These features help to monitor and control network traffic efficiently in complex installations.

Yes, the 1783-BMS20CA supports Device Level Ring (DLR), a Layer 2 ring redundancy protocol used in EtherNet/IP networks. DLR allows the switch to detect network failures and recover within milliseconds, ensuring high availability for time-sensitive applications. This feature is particularly valuable in safety-critical systems or production lines that require constant uptime. DLR can be used in both linear and ring topologies. It integrates seamlessly with other Rockwell DLR-enabled products.

No, the 1783-BMS20CA switch has been officially discontinued by Rockwell Automation as of September 1, 2024. This means the device is no longer available for sale and should not be specified in new designs or installations. Customers currently using this switch are encouraged to plan for its phase-out by migrating to its recommended engineering replacement, the 1783-CMS20DP. Rockwell typically supports discontinued products with documentation and limited service, but long-term use is not advisable without a transition plan. It’s important to evaluate replacement compatibility, especially if used in validated or safety-critical systems.
