Industry Applications for the Stratix 5700
In manufacturing lines, DLR enables a ring topology that maintains communication even if a cable is severed, minimizing downtime. For motion control systems, CIP Sync provides the accurate timing needed for coordinated multi-axis operations. The conformal coating also makes this switch a strong candidate for environments with high humidity or airborne particulates, such as food processing or automotive assembly.

Installation and Setup Guidance
When deploying this managed switch, consider the following practical steps. First, ensure the power supply meets the input voltage range specified in the full documentation. Use the console port for initial configuration, setting up IP addressing and enabling DLR if a ring topology is required. For the combo ports, select either copper or SFP media based on distance and bandwidth needs. The predefined Logix tags and FactoryTalk View faceplates simplify integration with Rockwell Automation systems, reducing commissioning time.
Maintenance and Reliability
Regular inspection of the switch’s environment is key to long-term reliability. Check that ambient temperature stays within the -40 to 60°C operating range and that relative humidity remains between 5% and 95% non-condensing. The conformal coating reduces the need for frequent cleaning, but periodic visual checks for dust accumulation on SFP ports are recommended. No internal user-serviceable parts exist; contact qualified personnel for any repairs.
Selecting the Right Industrial Network Backbone
When designing resilient industrial networks, the choice of switch directly impacts uptime and diagnostics. The Allen-Bradley 1783-BMS20CGP, part of the Stratix 5700 series, offers a robust foundation for demanding environments. This managed Ethernet switch provides 20 ports in a compact form factor, including 16 copper Fast Ethernet ports, 2 fiber Fast Ethernet ports, and 2 Gigabit combo ports. Its conformal coat protects against dust, moisture, and high temperatures, making it suitable for harsh industrial settings.

Compatibility and Integration
It supports Add-On Profiles for quick configuration and provides CIP Sync for IEEE 1588 precision time protocol. DLR capability allows the switch to participate in resilient ring networks. The managed switch also offers full firmware features for advanced network management, including diagnostics and alarming.
