Allen-Bradley 1783-BMS10CA – 10-Port Managed Ethernet Switch | Stratix 5700 Series
The Allen-Bradley 1783-BMS10CA is a purpose-built industrial managed Ethernet switch from Rockwell Automation’s Stratix 5700 series, engineered for demanding EtherNet/IP control networks in manufacturing, process, and critical infrastructure environments. Designed to integrate natively with Rockwell’s Studio 5000 and FactoryTalk ecosystem, this switch delivers carrier-grade reliability with the configuration simplicity that automation engineers require.
Product Positioning: The 1783-BMS10CA targets mid-scale control network segments requiring deterministic communication, IGMP-based multicast management, and DIN-rail mounting in panel environments. It is the preferred choice for system integrators building EtherNet/IP device-level rings (DLR) and linear/star topologies in automotive, food & beverage, oil & gas, and discrete manufacturing.

Proven Application Environments
- Automotive Assembly Lines — DLR ring topology for zero-downtime PLC-to-drive communication
- Food & Beverage Processing — Washdown-adjacent panel installations with redundant 24 VDC power
- Oil & Gas Upstream/Midstream — SCADA edge nodes requiring IGMP multicast and VLAN segmentation
- Pharmaceutical Manufacturing — Validated EtherNet/IP networks with audit-trail SNMP logging
- Water/Wastewater Treatment — Remote RTU panels with wide-temperature tolerance
- Discrete Manufacturing (MES Integration) — Layer 2 segmentation between OT device level and cell/area zone
Engineering Advantages
- Native EtherNet/IP Integration — Appears as a standard I/O device in Studio 5000; port diagnostics readable directly from ControlLogix/CompactLogix programs
- DLR Ring Supervisor — Sub-3 ms fault recovery on device-level ring; eliminates single point of failure at device layer
- Cisco IOS Foundation — Familiar CLI for IT/OT convergence teams; supports ACLs, port security, and 802.1X authentication
- Dual Redundant Power — Independent 24 VDC inputs with alarm relay output for power-loss notification
- IGMP Snooping & Querier — Prevents multicast flooding on I/O scanner networks; critical for CIP Motion and Produced/Consumed tags
- QoS Prioritization — 802.1p and DSCP marking ensures motion and safety traffic is never starved by HMI or historian traffic
- Compact DIN-Rail Form Factor — 45 mm width fits standard 24-slot panels without dedicated switch bay
System Architecture & Signal Flow
In a typical Purdue Model Level 1–2 deployment, the 1783-BMS10CA sits at the Device Level (Level 1), aggregating I/O adapters, drives, and safety controllers onto a managed segment before uplink to the Cell/Area Zone switch (Level 2) via the SFP gigabit uplink. VLAN tagging isolates motion traffic (VLAN 10) from standard I/O (VLAN 20) and HMI (VLAN 30). The DLR ring supervisor monitors ring health and executes automatic reconfiguration upon link failure, with fault status mapped to a ControlLogix tag for PLC-level alarming.
Recommended upstream pairing: Stratix 5410 or Stratix 8300 at the cell/area zone for full Rockwell-managed topology visibility via FactoryTalk Network Manager.

Technical FAQ
Q: Is the 1783-BMS10CA compatible with CompactLogix L3x controllers?
A: Yes. The AOP (Add-On Profile) supports all ControlLogix and CompactLogix families running firmware 20.x and above. Port diagnostics are accessible via MSG instruction or direct tag mapping.
Q: Can this switch operate as a DLR ring supervisor and a standard node simultaneously?
A: No. A port configured as Ring Supervisor cannot simultaneously participate as a ring node. Dedicate one switch per ring segment as supervisor.
Q: What SFP modules are compatible with the combo uplink ports?
A: Rockwell-approved SFPs include 1783-SFP1GSX (multimode fiber), 1783-SFP1GLX (single-mode fiber), and 1783-SFP1GCX (copper). Third-party SFPs are not officially supported and may trigger IOS compatibility warnings.
Q: Does the switch support PROFINET or Modbus TCP?
A: The 1783-BMS10CA is optimized for EtherNet/IP. It will pass PROFINET and Modbus TCP frames transparently at Layer 2, but has no native PROFINET IO controller/device functionality.
Q: What is the difference between 1783-BMS10CA and 1783-BMS10CGL?
A: The BMS10CGL variant adds 2 × gigabit copper uplink ports (instead of SFP combo) and extended temperature rating (−20 °C to +70 °C). Choose BMS10CGL for outdoor or harsh-environment panels.
Q: Is a Cisco SMARTnet or Rockwell TechConnect contract required?
A: Not for basic operation. However, firmware updates and TAC support require an active Rockwell TechConnect Support contract. Konmask can advise on support contract procurement.
