Allen-Bradley 1783-BMS06SA Replacement for Stratix 5700

Product Overview

Allen-Bradley 1783-BMS06SA Replacement for Stratix 5700: Seamless Network Migration & Upgrade Solution

The Allen-Bradley 1783-BMS06SA is a 6-port managed industrial Ethernet switch from the Stratix 5700 series, designed for demanding plant-floor network environments running on EtherNet/IP and standard IEEE 802.3 Ethernet protocols. As legacy Stratix 5700 units approach end-of-life or become increasingly difficult to source, many system integrators and plant engineers are now executing controlled network infrastructure upgrades — replacing aging or discontinued 1783-BMS06SA units with verified, tested equivalents to maintain uptime and preserve existing network topology.

TOPNLMS supplies the 1783-BMS06SA as a direct replacement module, fully compatible with existing Stratix 5700 network architectures. Each unit is sourced, inspected, and shipped with a 12-month warranty, making it a reliable procurement choice for both emergency replacements and planned modernization projects.

Seamless Upgrade Solutions

A successful migration from an aging plant-floor network to a modernized EtherNet/IP architecture around the 1783-BMS06SA typically involves coordinating several interconnected components. During the upgrade process, engineers commonly work alongside the 1756-EN2T EtherNet/IP communication module installed in the ControlLogix backplane — this module bridges the 1783-BMS06SA switch into the broader ControlLogix control system, enabling seamless tag-based communication without reprogramming the PLC logic.

For sites migrating from older SLC 500 or MicroLogix networks, the transition often requires adding a 1761-NET-ENI serial-to-Ethernet adapter or upgrading to a CompactLogix L3x controller with native EtherNet/IP support, which then connects directly through the 1783-BMS06SA switch fabric. In these scenarios, the switch’s IGMP snooping and RSTP ring topology features become critical for maintaining deterministic scan times across the updated network.

On the I/O side, distributed 1734 POINT I/O adapter modules and 1769 CompactLogix I/O expansion modules are frequently connected through the Stratix 5700 switch, and the 1783-BMS06SA’s managed port configuration allows engineers to assign dedicated VLANs to separate safety I/O traffic from standard process data — a capability absent in the unmanaged switches it replaces. The switch also integrates cleanly with PowerFlex 525 and PowerFlex 755 variable frequency drives communicating over EtherNet/IP, preserving existing drive parameter configurations and eliminating the need for drive re-commissioning during the network upgrade.

For HMI connectivity, PanelView Plus 7 terminals already deployed on the plant floor connect directly to the 1783-BMS06SA without any wiring changes, as the switch supports standard 10/100 Mbps auto-negotiation on all ports. Engineers migrating from older Stratix 2000 unmanaged switches will immediately benefit from the 1783-BMS06SA’s port mirroring capability, which simplifies network diagnostics during commissioning. Additionally, the 1783-US5T unmanaged switch can be retained in non-critical segments of the control cabinet, with the 1783-BMS06SA serving as the managed aggregation point — a cost-effective hybrid architecture that avoids a full rip-and-replace of the existing network infrastructure.

Power delivery to the switch is typically sourced from a 1606-XLP72E power supply or equivalent 24 VDC DIN rail PSU already present in the control cabinet, requiring no additional power infrastructure changes. This makes the 1783-BMS06SA one of the lowest-disruption upgrade paths available for Stratix 5700 network modernization projects.

Retrofit Guidance FAQ

Q: Can I reuse existing Cat5e/Cat6 cabling when replacing my old switch with the 1783-BMS06SA?
A: Yes. All six RJ45 ports support standard Cat5e and Cat6 patch cables. No rewiring is required in the majority of retrofit scenarios, significantly reducing installation time and downtime risk.

Q: Do I need to reconfigure my PLC program after installing the 1783-BMS06SA?
A: In most cases, no. If you are replacing a like-for-like Stratix 5700 unit, the IP address and port configuration can be restored from a backup. If migrating from an unmanaged switch, the PLC program itself does not require modification — only the switch configuration (VLAN, QoS, IGMP) needs to be set up via Logix Designer AOP or the web interface.

Q: Is the 1783-BMS06SA compatible with EtherNet/IP implicit (I/O) messaging?
A: Yes. The switch fully supports EtherNet/IP implicit messaging, multicast traffic management via IGMP snooping, and unicast explicit messaging — all essential for real-time PLC-to-device communication in ControlLogix and CompactLogix systems.

Q: Will the switch fit in my existing control cabinet DIN rail space?
A: The 1783-BMS06SA uses a compact DIN rail form factor consistent with the Stratix 5700 family. It is dimensionally compatible with standard 35mm DIN rail installations and occupies the same footprint as other 6-port Stratix 5700 variants, making physical installation straightforward.

Q: What communication protocols does the 1783-BMS06SA support for system integration?
A: The switch supports EtherNet/IP, IEEE 802.3 Ethernet, RSTP (Rapid Spanning Tree Protocol), IGMP v1/v2 snooping, 802.1Q VLAN tagging, and 802.1p QoS prioritization — covering the full range of protocols used in modern Rockwell Automation control architectures.

Q: How do I migrate configuration from a failed 1783-BMS06SA to a replacement unit?
A: Configuration can be restored via the Logix Designer Add-On Profile (AOP), a saved .cfg backup file, or manual re-entry through the switch web interface. TOPNLMS recommends maintaining a configuration backup as part of standard spare-parts management practice.

Warranty Assurance

Every 1783-BMS06SA unit shipped by TOPNLMS is covered by a 12-month warranty from the date of delivery.
