Why Engineers Specify This Model
- Native EtherNet/IP & CIP Integration – Seamlessly integrates with Logix controllers (ControlLogix, CompactLogix) via Studio 5000 and RSLinx, enabling topology discovery and port-level diagnostics from within the PLC environment.
- Device Level Ring (DLR) Support – Achieves sub-3 ms ring recovery, eliminating single points of failure on the plant floor without complex spanning-tree tuning.
- Stratix SmartPort Technology – Auto-configures port settings (speed, duplex, VLAN, QoS) based on connected device type (controller, drive, HMI, camera), reducing commissioning time.
- 20-Port Density in a Single Unit – Consolidates wiring for large machine cells or panel networks, reducing cabinet footprint and BOM cost versus cascading smaller switches.
- Cisco IOS-Based Firmware – Familiar CLI and web GUI for IT/OT convergence teams; supports SNMP v1/v2c/v3, RSPAN, port mirroring, and 802.1X authentication.
- Dual-Input 24 VDC Power – Redundant power inputs prevent network downtime from a single PSU failure.

Application-Specific FAQ
- Q: Can the 1783-BMS20CGP be managed directly from Studio 5000 Logix Designer?
- A: Yes. When connected to a ControlLogix or CompactLogix system, the switch appears as an EtherNet/IP device in the I/O tree, enabling topology view, port diagnostics, and alarm integration without leaving the PLC programming environment.
- Q: Does this switch support Device Level Ring (DLR) as a ring supervisor?
- A: Yes. The 1783-BMS20CGP can operate as a DLR ring supervisor or ring node, providing sub-3 ms fault recovery for connected EtherNet/IP devices.
- Q: What SFP modules are compatible with the 1783-BMS20CGP?
- A: Rockwell-qualified SFPs include 1783-SFP1GSX (multimode), 1783-SFP1GLX (single-mode), and 1783-SFP100FX (100 Mbps multimode). Third-party SFPs are not officially supported and may cause firmware warnings.
- Q: Is this switch suitable for use in a PROFINET network?
- A: The Stratix 5700 is optimized for EtherNet/IP / CIP architectures. While it will pass standard Ethernet frames (including PROFINET), it does not natively support PROFINET MRP ring redundancy or PROFINET-specific diagnostics.
- Q: Can I use this switch in a panel rated for Class I Division 2 / Zone 2 hazardous locations?
- A: The 1783-BMS20CGP itself is rated IP30 and must be installed inside a suitable purged or pressurized enclosure to meet Class I Div 2 / ATEX Zone 2 requirements. Consult your local safety authority for enclosure selection.
- Q: What is the difference between the BMS20CGP and BMS20CG variants?
- A: The “P” suffix denotes PoE (Power over Ethernet) capability on the copper ports, allowing the switch to power PoE-compatible devices (IP cameras, wireless APs, PoE-enabled I/O) without separate power injectors.
